bluetooth

does each different rom affect the range of bluetooth cuz im using the t-mo mda us and its ****ty when it comes to the bluetooth i just got the h700 and omg its horrible when it comes to reception is there a way to make the reception better or is it the headset.
well i guess my question is does the rom your using affect it?

It could, depending on whether the BT stack has changed. The Wizard uses the Microsoft BT stack, so it should be the same amongst the various carrier ROMs within a AKU version.

[Q] nook color has fm radio chipset

According to androidtablets.net not only does the the nook color have a bluetooth chip but also a fm radio chip but with stock os you cant use it of course. Does this mean that with cm7 you can also access the fm radio ability like it allows you with bluetooth? If anyone knows please post below.

No, the FM chipset is not connected to any sort of antenna therefore it does not work, regardless of if your running stock or CM.

Ok but could it be possible to add an wire antenna? Or could you add one like that of an android phone as someone did with an htcs speaker and added it to the nook or is it impossible?

Some phones use headphones as the antenna. I wondered this about the nook, but never cared to find out.

Good Question

I have wondered about this myself. I bought and learned how to root my Droid 4 for the sole purpose of having the FM radio. I am working on getting my Nook Color to run CM7, and found your post when I searched. I know on my D4 I needed to have it rooted and installed Spirit FM, it works well with the headphones attached. I also found a way to make an antenna using a Radio Shack plug and the antenna off an old cordless phone handset, It works surprisingly well! I don't see why it wouldn't work for the NC, IF it has the fm chip, and IF we can access it. I don't know if Spirit FM has been tested with it or not, but it's worth looking into.

This has been addressed many times, in this forum and others. To my knowledge no one has gotten anything other than static from any app (Spirit included) with any headphones at any time. I'd guess that there is no connection between the radio chip and the headphone socket, for antenna functionality.
I haven't pursued this in a while though, so there could be newer info out there.

Hmmm

Been doing some digging since I last posted, and the news, I'm afraid, is not promising.
I learned that the FM receive and transmit (!) antenna functions of the WL1271 chip are on different pins than the WLAN/Bluetooth antenna pins.
In addition, there are dedicated FM Audio Out L/R pins which I would suspect are not provided for on the Nook board/module. It's not clear to me if these are the only outlet for any FM decoded by the chip, though.
These, along with the fact that TI pretty much abandoned the FM feature of this chip in the OMAP implementation, (by their own admission) make the FM radio function for us... challenging.

Challenging isn't the same as impossible, and it must surely be easier than trying to get CM7 installed to SD card for my NC. I'm beyond stuck on that one, been trying off an on for a year. It seems to me that if the problem lies in the hardware, we should be able to correct that. BTW, did I see correctly, there may be FM TRANSMIT capabilities?! That would rock!! I would be blissfully happy just getting FM recieve to work. If the pins aren't provided for on the NC board, what would be a possible way to correct that?

Unfortunately, even though there are some great resources around (see the Novaports sticky above, for one) there's just not enough solid info yet to discover whether there's access to the necessary pin. The whole chip is about 1/4 inch square, containing about 115 contact sites in what's called a ball grid array, or BGA, all on the bottom surface of that tiny, "wahfer-thin" speck. This is married to a daughtercard which brings the necessary contacts out to the real world and has some more circuitry (most notably the chip which handles the wireless/bluetooth antenna switching). There's no way to tell from the pictures I've found whether they designed any access to the FM receive pin for the outside world. And I'd bet good solid money that there's no access to the FM transmit pins (separate Antenna and Audio L/R).
So, not impossible, but the real question is, how much would you be willing to spend to re-engineer a new daughtercard to gain access to these things (if, in fact, they're not accessible)? It would undoubtedly be more than the price of a brand new tablet which already contains all these things and more.
If they did bring the RX pin out on the daughtercard, then it should be possible to do some microsoldering and a lot of what I've just said is moot. But without disassembling one I have no way of knowing. If this were the case, then Spirit would likely be the way to go, as I ran across indications that Mike was doing some serious digging into this issue last year. There's also an infinitesimal ray of hope for drivers from a ROM that somebody put together for one of the Droids, which uses the same chip, that apparently has FM working.
I suppose one moderately simple test would be to load up Spirit, and bring a moderately powerful FM transmitter right up to the base end of the Nook, hoping for some leakage through all the shielding, and see if a signal can be picked up. Unfortunately, unless the result were positive, we'd be no further than we already are.

Oh. Ok

So I guess the best thing I can do for the moment is to get CM7 to boot and try Spirit on it. I can do that, and I have a transmitter that might work too. I will post the results.

I got my NC running CM 7.2.0. Turns out I needed to rename the ROM and also something was bad on my SD card. I have been happily exploring CM7 and getting my google apps on my NC for 2 hours now. Among the apps I downloaded is Spirit FM, the free version for testing. It loads well, I plugged in headphones and an antenna and can't get a signal, not even static. I will look for my transmitter tonight/tomorow and see what happens then. Thanks for all the encouragement and support on the CM7 thing yall!

Houston, we have a problem. I have a stock nook running cm7 on sd card. Spirit FM Free with superuser permissions granted couldn't pick up the transmitter. :crying: I even put the transmitter right up against the nook and didn't hear anything, so it's not looking very good. I know on my droid 4 I had to have it rooted in order for the FM to work, I wonder if that is the case here? Anyone got a rooted nook to try this experiment out on? Once my warrenty is up I will try "nooting" and see if FM works then. If it is the daughter card, I am at a loss. Anyone got an idea about what we can do next? tonestertm, I can't find your Novoports sticky. Can you repost the link please?:good:

FM radio on nexus 6

I called T-Mobile and had them look into the FM chip in the nexus 6. They told me that the nexus 6 does have the FM chip but they will not active it. Does anyone have a patch that actives the chip? This is the website that made me aware that this phone can play FM stations.

Wow, that would be awesome. I'd love to listen to baseball games at work.

Links to the FCC reports for the N6 are here and here. There is no mention of an FM radio. You can also see the iFixIt teardown here. They also did not mention an FM radio.
As much as I would like there to be an FM radio in the N6, I think this is more likely a case where the CSM you spoke with was mistaken or the information available to the CSM is incorrect.

They called me back after researching it. They started off by telling me no it did not have it. After they researched they said yes it does. They also told me other providers will active it but not T-Mobile

That might be partly true. Many chipsets these days are multipurpose. I'll use my old Nook Color as an example, because it had a WiFi chipset that did, in fact, include a Bluetooth transceiver. The device's hardware, however, had zero provisions for it. Developers figured out how to turn it on, but without the supporting hardware, Bluetooth range was less than 32 inches, nevermind 32 feet.
I'll wager if it's true, it's the same case with the N6. It very well may have a chip capable of receiving FM radio. That does not, by any means, suggest that it has the required hardware to use it. I doubt very much it has any supporting hardware or antennas to use FM radio.

Who uses FM radio anyways when you can use an app like TuneIn Radio and listen over data without reception issues?

AFAIK, having an FM chip on a phone doesn't mean you can receive FM radio transmissions on the phone b/c you need a proper FM antenna. The Nexus 6 only has 1 antenna on it and it is designed for use by the GSM/CDMA/LTE radios, not by an FM chip.
So like with a walkman/ipod, you would need to use the headphone wire as an FM antenna BUT AFAIK there would need to be a coupling b/t the headphone jack and the FM chip and there isn't unless the phone was designed to use the FM radio There is in some phones like the Moto G and Moto E, but the phone has to be designed to use the headphone wire as an antenna AFAIK.

Also because in many cities, like Atlanta, the radio guys are just better than the "visual" guys. I often watch the game on tv but listen on WSB AM

One teardown I read (can't remember which) explained that the 805 comes with an FM chip, however there is no wiring from it to the headphone jack for antenna. There is also no system support included by Qualcomm to use it. Unlikely to get that working without serious hardware modification & software integration.

Sprint Nexus 6 Has FM Radio
The Nexus 6 on Sprint has the FM Radio activated out of the box. You can check the specs on the website, it is called NextRadio.

FM Radio
I'm in the broadcasting industry, and my radio colleagues say there's a conspiracy at work here. They swear that every cell phone made contains an FM radio receiver. But - carriers prefer you use data rather than free airwaves, so most block it.
I don't know if that's true. But I do have one piece of personal information.
I own the Sony Xperia Tablet Z. WiFi only. And yes, it has a built-in FM radio. Even has an app for 'FM Radio,' and it works like a charm. It apparently uses the headphone cord for the antenna.
Then I also bought the Xperia Tablet Z2, with Verizon LTE. And...there is no FM radio access at all. No app, no mention of it, anwhere.
As for the Nexus 6, a thought: aren't they all pretty much identical? So, if one has FM capability built in, won't they all?
Regardless, the issue is bigger than just this phone. The radio industry has been trying for years to get free radio on cell phones. But, it's just not going to happen on some providers, , since they make money on data. But for those that allow it? Bravo.

Eonon, Xtrons or Joying?

Hi All,
Im thinking of buying a new head unit for my BMW E90, are there any preferences over these brands? Im swaying towards the Eonon GA7165/GA8165 but i believe most of these units are all the same but branded differently?
<--Update-->
Right so after carefully considering everything for 2 years I finally bought one!
I've just purchased the Xtrons PE9890BIPL
https://xtrons.co.uk/bmw-3-series-android-8-0-pe9890bipl
It is on offer for just £239.99 which to me was a steal as second hand units (if you can find one) tend to sell for around £150+ because most people paid £300ish.
it has a beefy specced system of an Octa Core PX5 processor with 4GB RAM and a 32GB ROM running Android 8.0. This unit also has a big 9" screen at the expense of losing a DVD drive and some physical buttons (all of which can be used from your own steering wheel controls) but they offer the same spec with a smaller screen and contains the physical buttons if you'd prefer the physical buttons and DVD drive.
the newer head units running Android 9.0 aren't as good, currently offering a quad core PX35 processor (same x64 bit architecture but runs more efficient) and only 2GB RAM and 16GB ROM so it's a downgrade really.
Then of course we move onto the brilliant XDA forum for custom ROMS, and it just so happens they've already managed to get Android 9.0 onto these PX5 units
So I chose Xtrons because from what I've read most companies buy these units from the same supplier and brand them leaving other factors to be considered, for me xtrons is UK based so next day delivery, plus clearence prices, they also offered the beefier head unit, support seems okay (some chaps hasd ssues with steering wheel functions not working after locking and getting back into car, long story short they sent people new looms and sorted) and then on top of this XDA developers providing custom ROMS which can fix a lot of the common issues. I'll provide another update when it comes on Monday

8-core-px5 - Dasaita > All because of the different (stand-alone BT and WiFi chips)
4-Core-px3 - IMHO the only differnce is the OS. 7.1 has no custom roms yet, so yo probably have a bloated OS
difference at both to consider: AMP chip TDA7388 or TDA7850, clear recomindation is the TDA7850 because ist has way more power and sounds clearer and more crisp

Hey I'm new here.
Is the selection of AMP chip important ? Seems there's very few manufacturers using TDA7850.
The few that do use TDA7850 seem lots more expensive. Is this normal ?

1) BT and Wifi are going to be on the *same* chip, so don't need to pluralize that.
2) The positioning of that particular RF chip (whether it be on the SoM or the host board) doesn't *technically* matter. The downside to being on the host board is typically that the reseller may have a bigger part in writing software that interfaces with it, and reseller written software is always a very bad thing.
3) Intel Sofia units also have the wifibt and GPS chips on the SoM.
Even with the wifibt on the SoM, the resellers *still* manage to mess it up, however, it may be somewhat easier to clean up in this case.

I think it may have to do mainly with your needs and expectations.
Neither is going to satisfy anyone who self-identifies as an "audiophile".
I think the main differences are that the 7850 is slightly more powerful (4x50 vs 4x45 watt), and is ok with 2 ohm speakers where the 7388 is 4 ohm only.

I think it may have to do mainly with your needs and expectations.
Neither is going to satisfy anyone who self-identifies as an "audiophile".
I think the main differences are that the 7850 is slightly more powerful (4x50 vs 4x45 watt), and is ok with 2 ohm speakers where the 7388 is 4 ohm only.

Which make and model has the 7850 chip? I've just had a look at the Eonons, Xtrons and Joying units for the E90 and the most I have found is 4x48w and all the rest are the same 4x45w.

Not sure which chip mine got but I do have the Octacore GA7165A and I'm really happy with it just a few setup things I need to figure out. I also installed Viper4Android which improves the sound greatly only issue I'm facing is it does not apply to the MTC radio.

Probably because the radio analog output never touches the CPU. It goes RADIO --> BD37xxx --> amplifier --> speakers.
The BD37xxx is an audio processor/mixer. Bunch of analog inputs, bunch of analog outputs, i2c control from either the MCU or SoC depending in which vendor it is.

Hi mate,
Good to hear that Viper4Android works on the GA7165A model, so you've not experienced any other issues? On a YouTube video I've read various things such as Audio quality being poor through Spotify which is one of the main things I'd want, and also phone calls sounding muffled, though I assume that's probably down to the positioning of the Mic itself. What sound system do you have as well mate, is it stock or upgraded?

I’ve got the stock sound system of a 2006 E91 I have installed Spotify but I haven’t used it yet still waiting for my mifi device but I’ll give it a shot maybe tomorrow and let you know.
In terms of Bluetooth / phone Bluetooth music is very good and also works through Viper4Android for the phone function itself I’ve only used the internal mic so far and that is a bit quiet but I’ll install the external mic later in the hope that it will improve the volume issue.
One thing I did have was V4A wouldn’t start automatically until I installed it as a system app now or does that just fine and from a sound quality perspective it is not worse than the default Prof. Head unit if anything I would say better since I can set a more granular sound set-up ( I like deep bass when the radio is not too loud just like the loudness feature on other stereos).
Not sure where you live if anywhere near southwest London feel free to pm me and we can meet for a coffee and you can have a look at it

@mrsweet1991 Have not yet tinkered with the mic but I did try Spotify for you and can report it works just fine I left the Spotify EQ off and instead use V4A and the sound quality is as good as an MP3 on the USB.
Hope that helps.

Have now installed the external mic however I had to disconnect the internal mic to get good quality I might go ahead and solder the external mic onto the internal port so I can use that for OK Google etc as well but with external mic and internal disconnected the quality is good.

How can i root the ga8165 and install xposed framework?

Hi All,
Im thinking of buying a new head unit for my BMW E90, are there any preferences over these brands? Im swaying towards the Eonon GA7165/GA8165 but i believe most of these units are all the same but branded differently?

I recently purchased this unit (GA7165A)and installed it.
If you purchased this unit how do you like it so far?
By the way I have a L7 AMP (fiber) and had to do a bit of research to figure out a few functional work around.

Hi Mate,
Been such a long time since I've been on here, I just wanted to say a big thanks for the information it's good to know. I'm hoping one day I might get a break from fixing things on the car and actually get to stick an eonon unit in! Last time I here the 7165a was the best out and now there's a 8165a lol

Hi mate, I've not had a chance to buy one yet.. I seem to end up fixing the bloody car all the time haha. Walked in for an MOT and come out with a failure for a snapped rear spring and a couple of other minor things.. Starting to get back on track now though, so I take it you have the logic 7 system? Mines just the basic system with underseat subs so should be easier to setup but less rewarding on the sound quality side haha.

Also interested in buying a unit for my E90, just not sure how to pick a unit and know that im getting one of the more reliable manufacturers with stable software? Anyone have experience with the Eonon 8165A? seems like the best deal..

Can any GA8615a owners vouch for the sound quality? Is it any worse than the stock HU?

Question S21 Ultra FM radio (snapdragon)

Market/Operator/Dependent
Not all Snapdragon variants offer a built-in FM Tuner. My S9 and S10 were Global variants (Hong Kong). Both have built in FM Tuners but my Hong Kong S21 Ultra no longer supports the feature. Not sure why, maybe the CCP crackdown in Hong Kong has something to do with it.
You might give this a shot.

I've been researching this. What's been shared is the 3.0 UI Update removed the Samsung FM Radio for most users. A few devices in certain markets (Australia?) MAY have the utility. I attempted to activate the radio via the Nextradio App without success, they went out of business. I also attempted to install the most recent Samsung FM Radio AKP, again without success. The User Manual for my device (SM-G9980 - Hong Kong) makes no mention of an FM Radio. My wife's S10 Plus (Hong Kong) has the feature and it works fine. You can still install radio apps but the ones I've seen are all streaming with ads.

The manufacturers sometimes disable FM radio at the hardware level. So even though the acctual radio chip may be present on the phone, it's disconnected. No amount of software wizardry will tap into it if it's not enabled by Samsung at the hardware level. Older devices had workarounds, but as the community finds and uses loopholes to get around restrictions, comapnies like Samsung plug those loopholes in the next iteration. I've tried to search online for a way to get the S21U FM radio working, but I don't think it's possible at the software level unless Samsung explicitly enabled it from the factory.

I don't think it's going to happen. As far as I can recall, the older phones required that you use your wired headphones as the antenna. After all, FM antennas are fairly large if you want any sort of reception at all. The wire for headphones could work but the newer phones now don't have a headphones jack so there really isn't anywhere to use as an FM antenna. So, even if you could get the chip to work I really don't think it has any connection to an antenna for you to put up any signals.

I'm inclined to agree. It would seem manufacturers are looking to migrate users to streaming (pay for) options. The stock Samsung FM on devices which are equipped with the feature won't recognize the antenna via earphones connected via the USB port, only the 3.5 jack can be used for the antenna function. Looks to be an obsolete feature, service providers want to make profits for anything they provide.

They're making money by endangering public safety. An FM radio is a basic necessity during an emergency. They really ought to legislate access to weather, AM, and FM radio as a minimum necessity in 5 years. Just my angry stupid opinion.

No FM Radio for the sole reason that there is no headphone jack anymore. It is being used as an antenna for the FM chip so having an FM radio without an antenna is pretty much useless. No more no less. No need for conspiracy theories here.

"No FM Radio for the sole reason that there is no headphone jack anymore"
Totally disagree, if a 3.5 jack will accommodate the antenna a Type C Connector can accomplish this function just as easily. Conspiracy? How about common sense? It's all about $$$. Nextradio was unsuccessful at convincing Apple to activate the hybrid radio app on iPhones, that's why they tanked. Either way it would be a critical feature in an emergency setting, possibly a life saver, device manufacturers are well aware of this.
