Hi,
I want to extend my Rasberry Pi based smart home system with control UI:s utilising MQTT. I'n noobie on MQTT so I decided to ask recommend open source MQTT broker implementations available for Rasberry PI. I'm mostly Kotlin/Java dev so I'd prefer implementations that I could hack with Kotlin/Java.
I am considering Exclipe's Paho since I'm going to use Paho client on my Android devices.
Any recommendations?
Thx

Any word if and when Android will support MAP and other profiles?
Is there a possible workaround in the meantime?
Okay, what about utilizing iAnywhere Blue SDK? Anyone tried incorporating it?
This must be a taboo subject - there is literally no information anywhere on this. The only thing I could find is that Marvell has licensed the Android version of Blue SDK. Blue SDK for Andorid integrates MAP and a whole host of Bluetooth advanced profiles at a software level but I can't find anyone who has reported any experience with it.
Seriously, the iPhone and Blackberry all have built in support for advanced profiles. Android needs to get on board ASAP - the advanced profiles are crucial for automotive apps and next generation in-vehicle information/entertainment systems.
Does anyone have a contact with the Android developers they can PM me so I can try and find out if this is in the cards at all? This is terribly frustrating....
If you look the Droid 2/X it has support for MAP and some other protocols that the other android phones don't have. I'm currently looking at the Droid line to figure out where this support is and maybe see if I can port it to the Nexus.
A team I am on is currently working on an autonomous quadcopter (AR.Drone 2.0 as the platform) that would have to navigate by itself, as well as identify some writing on a sign (made up language, we have been provided an image of what the writing will look like) and identify an object on a desk. Does anyone have any experience using a RP for CV? We are looking at possibly implementing OpenCV, at least as a base.
I was doing my first raspberry pi electronic project. I choosed the adafruits Google docs logging project for a start. The project was a success and I obtained a complete output. My problem is , when I looked into the python program provided by adafruit (got it from github) it is calling other small programs. So I looked one of the called programs and it again calls other program.
I want to write a complete program that includes all the necessary things ie a stand alone version.
I want to write it in python 2. Also use a gpio pin 5. My model of pi is raspberry pi 2 model b.
I don't know whether I can include driver in my program. But if it is possible , I also want to include the driver too, please help me.
Hi,
I want to create a custom keyboard using a Raspberry Pi. I have a very limited knowledge in Hardware and Electronics. But I know how to code in Java/Python/C/C++ very well.
The keyboard should be able to store every text file that I type into it. That is, it should have an internal storage. Additionally, it should be able to connect to any Android/iOS/Windows device like smartphone, tablet etc, so that all text content typed is shown in the required device in real time. All text typed should also provide real time audio feedback. As a trial I have created 2 prototypes where one is running on Raspberry Pi with internal storage with real time audio feedback. And another device which runs on Arduino Leonardo to connect to hand-held devices. But for the final product we need to create a single device with both features in built.
In summary, here are my requirements:
Audio feedback: Recites every word I type in real time through headphone jack.
Internal storage: The keyboard should have an internal storage slot to store what I type.
Portable: It should be easy and light to carry around.
Cost effective: It should use cost effective solutions/materials.
Plug-N-Play: Connect to any Android/iOS/Windows device like smartphone, tablet etc. and act as external keyboard.
Battery Life: The keyboard should have a reasonable battery life.
Questions:
Which model of the Raspberry Pi should I use to create the keyboard. It needs to be an most inexpensive model which can satisfy all the above requirements. Is it possible to use the Raspberry Pi Zero and then add any required modules?
We need a USB HID + Linux version that runs Python or any other distribution with text to speech. Currently, for a prototype, we are using Arduino Leonardo for USB HID and Raspberry Pi (B+ Model) for Text to Speech conversion (we are using Espeak at the moment).
I have a custom design for the keyboard but the ports of the raspberry pi don’t align with the custom design. What options do I have here? Example: Assume, I want the headphone jack to be on the side of the keyboard. But the headphone jack is placed at the bottom in the raspberry pi.
How to create the outer casing for the product? Again, I want to use only cost effective material, yet it should look as professional as possible.
Thanks!!!!!!!!!!!!!

Plz ping me i want to know about your project
Hey all,
I'm about to start developing an open source project for managing android devices from a Linux machine.
Technology stack is going to be;
Symfony (5.1 / PHP 7.4)
VueJs 2.* (ECMAScript 6 / TypeScript/ Buefy)
I'm still setting up the architecture for the backend and yet to begin on the frontend. For the frontend I've got a prebuily VueJs codebase I can use for the frontend architecture
Preliminary road map
Devices details
File manage
Screen interaction (Screenshot, record, touch control)
APK manager
Root / Fastboot tools
Where possible (at least in the beginning) I was to avoid functionality that is specific to devices and custom roms.
If you interested in getting involved drop me a reply on here. Eventually looking to distribute this over APT so would be really good for someone looking to add to or start there portfolio.
