Please help me change BT1.2 into old BT1.1.

I have a need for a BT repeater, http://omni-wifi.com/mobile-spot.html , will repeat any frequency from 2.4GHz - 2.483.5GHz.. This is the same as BT. It does not latch on the the SSID of a WIFI router like the other WIFI repeaters, it "repeats" on the frequency level.... HOWEVER, it does not do well with frequency hopping like with BT 1.2.
So, is there some reg setting in my PDA2 that can switch it to 1.1?
Or is it something in the BT stack that is unchangeable?
I know the hardware is the same and the only difference between 1.1 and 1.2 is the frequency hopping.
Or, does any one know if the frequency stays the same during a connection.. For example, does BT1.2 hop around and search for the best channel during "standby" and then picks a channel and sticks to it during the active connection?
FYI, I need this so I can leave my phone in the work truck and only use my BT headset because I have a cell phone repeater in my work truck and I travel outside normal cell service all the time.
Thank you

One issue ive never seen mentioned>

Hello everyone
I recently, (finally) ordered a headphone/usb splitter thingy so i can play my tunes off the tilt in my car. Either thru an fm transmitter or a headphone/tape converter i put in the tape deck in my car. First off, im totallly impressed how great the sound is thru the stereo, a combo of car stereo settings/ and the audio booster/equalizer make even slayer sound good at the proverbial (11).
My question is this, im not sure if the att sites around here are jacked way up (power-wise) or what. But that annoying beeping, fluttering, digital sound you get thru your house speakers if you set your phone to close (or your tv or anything else w/a speaker for that matter)... its happening in the car also.
I can understand when im using the youtube player, the thing is streaming.
But even just playing mp3's or watching a movie thats on the SD card, i still get it from certain towers in certain towns. We have hellacious service here in New England, with alot of the towers on major routes not even doing handoffs correctly, resulting in missed calls etc. So i have a reason to wonder if its the service im getting i suppose.
Being the (non) brainiac that i am, i took a shield from a 25 pair cable i was punching down at work the other day, and put a large piece of it over my headphone wire/connector. Would this do anything? Is there such a device you could buy? (some sort of RF/emf shield?) It seems to work if the phone itself is the problem (youtube)... however coming thru by a certain cell tower again the other morning, that thing was chirping and burping like 2 dollar gutter whore.
Any suggestions or comments on this are appreciated, sorry for the rambling.

I live in North Mississippi near Memphis and have experienced the same issue. Sorry that I am no help towards a solution. Just thought I would let you know you are not alone.

Nope, the RF emitted by the phone is acting direclty onto the low level circuitry inside the car radio.
Even if you're not streaming anything, when the phone switches to another cell toper it notifies it that it has done so, and thus will communicate for a moment. How often it will do so, whether it will be on every tower or only after defined amounts of time, or even every group of X towers is defined by the operator. If you say coverage is know to be bad they might have just set it to notify on each tower and the phone is often switching.

Sometimes placing your phone on an antistatic bag, like Hard Drives come in helps. At least it does with computer speakers.

The noise is referrd to as RFI (Radio Frequency Interence) and EMI (Electro
Magnetic Interference). Both of these are what is affecting your system.
As your phone gets POLLED (Where are you message) by the cell phone tower, it responds with a "Here I AM" message. Its this initial communication
(handshake) that that is causing the interference.

From another website:
"a cellphone tower can only support a limited number of simultaneously
connected cellphones. It therefore needs to know exactly when a cellphone
leaves its range, or disconnects from the network altogether, so it can free
up its connection slot for use by another cellphone. Normally a phone
communicates a disconnect to the tower whenever possible (for example if
it's getting out of reach and connects to another tower, it then disconnects
from the first and the connection gets transferred gracefully from the old
tower to the new one, even in the middle of a conversation). However, if you
just yank out the batteries, the phone gets utterly destroyed, you suddenly
enter a cage of faraday or even an underground tunnel, ... the phone will
have no time to notify the tower, so the tower needs to check up on
supposedly connected phones from time to time to check that none of them are
MIA. It's basically similar to an ICMP ping on the Internet. And that's what
you hear over your speakers. Similar thing happens right before a call or
SMS comes in, or when you dial out: there's two-way communication, and the
RF interference the cellphone puts out is picked up by your audio
equipment."

Either move your phone, or turn it 90 degrees to the right or left. It has to do with the phone switching over to Edge (or if it's always on Edge, you're gonna get it regardless) and the speakers are picking up the radio traffic as interference. It shouldn't happen when the phone is on 3G/HSDPA. Just repositioning the antenna, i.e. the phone, has always worked for me. You could also look up distortion reducing tricks, there was something on Makezine.com about putting magnets on the speaker wires to get it to stop, but I couldn't find the entry right now.

Cool beans, thanks for all the info. I understand about handshakes and all that and figured that was exactly what was happening. Doesnt seem to matter 3g/H/E certain towers do it no matter what im doing. As i noted the towers around here have been having major issues w/ handoffs so who knows. BTW not only does your cellphone poll constantly, but usually your phone call is happening on at least 2 towers at a time. So once tower A gets more signal then tower B it switches over to A (which already has your call processing at the same time) So yea its gonna happen no matter what i do. Truthfully its not that big of an issue, but i just came up w/ the greatest cheapo mount, and of course where i have the dam thing is directly over the stereo. lolz
Thanks again!

wifi antenna?

is it possible to add a antenna to the wifi i notice what looks like a wifi antenna jack down by the battery connector is this wat it is would i simple use the wifi antenna from an old laptop and wrap it around inside the housing as my wifi range is horrible as it is now
Thanks,
yonu

i thought i would add a pic what I have circled I would assume is the wifi antenna jack

I am not trying to be a pain but u i need to figure something out as i mean this literally unless i lay the phone on top of the wifi router and i have tried this in several places i can't pickup a wifi signal.
Thanks,
yonu

What does this do?

http://www.xperiadepot.com/freedom-keychain-gps-2000/10A95A2869.htm
There are no good description for this product. Does anyone know what they do?

I think this is an ordinary gps modul and description made by someone who does not know there is already a gps receiver built-in in X1.

maybe you use it to help find your keys?

Right but the description confuses me and it does sound exactly like what jabe said. But I would so buy this if it was key finder.

It just a bluetooth GPS module that fits on a key chain. You don't need it as the X1 already has a built in GPS chip. If you had a smartphone without a GPS chip, then there's be some benefit to it.
Or if you wanted to use GPS stuff on a laptop or something with BT etc.

Suppose your X1 is positioned in your car that way that the GPS reception is bad but you cannot relocate it. You can set it up to receive GPS signals from this external module. The module itself can be put anywhere like near a window or on the car's roof or so.

WTF? Did you even read? "The Freedom Keychain GPS 2000 is the world’s lightest and most compact pocket GPS receiver."
It's an external GPS receiver.

gps is receiving only!
you pick up a signal from several satellites and the device calc your position
this keythingy have gps and bluetooth
bluetooth have a range of 10m so even if it could transmit
it's cords to your phone then you would have to be pretty close to the lost keys

an external gps, my brother has one but of a different brand. his loads really quick and there's no need to wait on finding satellites. i'm not sure how this performs though, but for a keychain it seems promising for other phones without a built-in gps

I actually have one of those. Well, mine is a white Vodafone branded one, but it's the same chip, hardware, box, everything. It's actually still vaguely useful - it's DGPS capable (WAAS/EGNOS), which the X1's GPS chip is not (augmented accuracy within certain systems, WAAS for North America/Canada and out to sea within several hundred miles, EGNOS for Europe etc), and it has apparently far better reception - my X1i couldn't pick up a GPS signal to save its life inside a BA Boeing 777 flight. The bluetooth'd external reciever picked up and held a strong signal for the entire 3500 mile flight at 40k ft. And inside a plane fuselage, that's got to be borderline faraday cage.

USB DAB+ devices and signal strength

Hello to all...
Just wan't to solve some issue with USB dab+ signal.
I bought Dab+ usb dongle (https://www.aliexpress.com/item/32861687291.html?spm=a2g0o.order_list.0.0.21ef18023f5v55) and now is connected to my multimedia device (ALPS FF5000 / 8227L chipset) in car (Peugeot 308 mk1 2011y). Installed an app called DAB Z for running DAB+ radio.
Supposedly, the signal is stronger and good when used without lights on the car, but when you turn on the lights, the signal simply disappears or is zero.
I noticed this when I started the car radio without the engine running. When I turn on the car and the lights (both the car radio and its lights come on - which means it draws energy from the battery and may take extra power to power the usb ports where the usb dongle is) the signal is simply lost. How do I solve this, when I turn on the lights so the signal doesn't go away, does anyone know?
Thanks to everyone in advance for your help!
Best regards!

Those DAB+ antennas are garbage. Buy proper antenna, but only antenna, and keep this usb dongle. Those glass mounted antennas only works in really great conditions.

Yes I noticed , I bought another one better signal is stronger, but I noticed also that problem was in led lights installed in car. They cause interference of antenna if no resistors installed with led bulbs. I removed them and put origin al H7 bulbs and now signal is great. But I'm in to solve that problem with lights and antennas. Have you come across this problem ?

Hm. I don't remember anymore. I also think I had some problems when I turned on ignition in my car. But I never researched, if the issue was led lights or anything else. I just bought better antena, that I mounted on the roof, and since then, I don't have any problems with signal anymore. I can listen to DAB+ radio in most remote areas possible. I also noticed that if I put this better antenna inside the car, signal drops instantly. So I have to put it on the roof.

I have bought 3 in 1 antenna amplifier . Dab+ and Fm. It strenghten signal significally. I resolved this problem but still, problem remains with led lights as they don't have any resistors and cause interference with antenna.
