Fm transmitter - Xiaomi Redmi Note 3 Questions & Answers

First, i love this forum so much
second
i want to send a fm signal to open my gate that work on fm in 91mhz so what i need to do this ?
fm dongle + otg and app ?
anyone already think about that
(obs: i dont see any place on the forum to talk about that)

You could set up a raspberry pi for opening the gate and connect to it through wlan. That way you don't need extra hardware on your smartphone.

but i want the solution without any hardware on the gate but in my phone ok....

Concerning both this and your previous request:
Transmitting data over bluetooth to FM simply is not possible. The bluetooth standard goes at the 2.4GHz frequency range, while the FM standard doesn't even hit 1GHz (i think). Bluetooth is a DIGITAL signal, while FM is an ANALOG signal (once again, i think).

Android as a2dp bluebooth receiver?

I know its possible to send audio from an Android phone via bluetooth to a PC using the a2dp profile. But I want to do it the other way. Connect the phone to my amplifier and send audio via bluetooth a2dp from my laptop.
I've searched but not found. Anyone know it it's possible?
I think the standard BlueZ stack can't do this. I think the Broadcom BTLA stack might be able to do this ... IF you have the Broadcom Bluetooth chip inside.
Hi Pananza,
did you have success to use an android device as a2dp receiver? I'm looking for a solution but I didn't find anything useful.
The only solution that I have found is to use the NDK to access the BlueZ stack, but I'm not sure if this is the right way.
Thanks

Using phone as A2DP receiver
Hello
I would like to do this too, have a Sony MW600, and it works perfect with laptop or my HTC Desire, but it can not be charged and used at the same time..
Will it be possible to do this on an Android that is not rooted?
Did anything ever come of this? I'm looking for an app that would allow android to receive bluetooth a2dp or whatever the basic format is (mono ok), and output audio on the headphone jack of the phone. Bass ackwards to what all other apps i've found are doing. I've always been a "special needs" user

any update on this?
Wanting to use Android OS in the dash of my vehicle hooked to the audio system and use bluetooth a2dp to connect to mobile phones to play media through the system.
I'm looking for a similar setup. Has anyone found a way to turn android into an a2dp receiver?

You can transform your device into a wifi music receiver with the app called soundwire, you must install a server on your pc to stream audio from your pc to your android device. I didn't find anything with bluetooth.

Same here. More and more people are going to have "last years" android phone lying around doing nothing and this would be an awesome way to re-purpose it.
Whether it uses BT, Wifi, I don't care as long as I can stream audio from one android phone to another. What I don't want is to deal with DLNA or manufacturer built in BS. Just need google to turn on the A2DP sink profile and be done with it. The hardware is all there, just need the software to take advantage.
The next best thing is one of those BT reciever dongles/boxes. They run about $20 I think. So PSA to android developers - if you can enable this in a paid app I'm ready to buy it and I'll bet a lot of others are as well.

Did that tutorial works for you?
I've tried, but it doesn't work. My Panasonic TV doesn't see my phone, so I cannot play the TV audio thru my phone.
Any ideas?
Thanks!
I was also looking for an app like this.
For my old phones, my android sticks, ... no progress I assume ?
Waiting the same here! My idea is to buy a bluetooth transmitter, connect it to my TV and receive the audio on my phone.
I can't think that is not possible! :crying::crying:
Truck Tablet Install
Hey Everyone,
Been very curious about this as well as I'm going to do a nexus 7 install in my truck and want to be able to bluetooth additional music aside from what is on the tablet through the tablet to my speakers. Kind of a necessity due to the lack of a 3.5mm aux into the stereo. Hopefully we can figure this out!

?
I'm also looking to do this.
I'd like to be able to connect a Bluetooth transmitter to the output of a mixing desk, and then just use my phone to receive the audio (which I'd then want to save with something like tapeatalk).
This could provide a very quick method of recording gigs or DJ sets in stereo, and would be better quality than simply using the built in mic of your phone.
a2dp sink.
Bluetooth File transfer app can stream music from another phone. And this is where tha first phone works as a a2dp sink am I right? Can't we use that to built an app to follow it but using pc/laptop as the source?
Seems, that no one is interested. What a pitty, it could be really HOT stuff. For example, cheap android phone pluged instantly to a charger and to Car Audio via AUX, and You have got Bluetooth automatic pairing system for calling and music, navi etc.
Unfortunately I couldn't find solution for this, neither the app. It is strange. Some people says, that Android can not be a sink (reciever) in a2dp profile. So how does microphones from earphones are streaming audio to a phone, hmm?
Maybe someone will do it
I have a LG G3 and it does it flawlessly. It have a function called "Turn Audio Channel mode" on bluetooth settings.
I'm wondering how to do the same thing on any other andoird phones.

[Q] Road Veles Android car stereo add bluetooth support?

Hello all,
I'm after a little bit of guidance on how I might add Bluetooth support to an Android powered Car stereo. It is a "Road Veles" single DIN WinCE and Android device with a 7" flip out screen. The reason I bought this stereo is to run an app by the name of MSDroid. This app was to connect to my vehicle's engine management system via Bluetooth.
Can't post links yet, easy search on Google for Road Veles, look for hit on Chinavasion
The specs say it has Bluetooth, but having tested the device out on the work bench what the specs don't say is that the bluetooth is only accessible for handsfree from WinCE, there is no bluetooth for Android. WiFi via USB dongle works great. I have purchased but not yet received a combined WiFi and Bluetooth dongle. I would very much like to have this combined dongle work with the device. The Bluetooth control is not visible under WiFi control inside settings like it is in my Android phone.
Can anybody point me in the direction of where to start with this? Can I root the device and mod to add bluetooth? Is there another ROM I could run? I have done a lot of searching but can't see much at all out in internet land on this stereo!
Any help greatly appreciated! Thanks in advance,
Arran
Hi, I'm not sure how these sort of things usually work, what sort of dollar value would usually be associated with making a some tweaks to an Android build? ...
Hi again, still looking into this. Any ideas how to tweak the Android 4.0.4 OS to make bluetooth appear inside the settings menu?

Fm receiver dissabled ? or Absent

FM radio through Bluetooth headset

Hi!! I was wondering if there's any way of listening to the fm radio through the Bluetooth headset instead of using the wire one or the speakers. I saw on the Samsung s9 that the radio app has and option to output the sound through the Bluetooth device connected but on the poco is doesn't exist.
I tried to install the s9 apk into the poco but it didn't work and I don't see that the poco has any way of selecting when having Bluetooth and wire headset connected.
I know that the wire on the headset works as the fm antena but I make it work just by cutting the plug of an old headset and plugging it in to trick the radio, now all I need is to be able to redirect the sound to the Bluetooth
I'd expect there would be an app that can just copy the audio output that's going to the headphones to the BT output.
There's an app called TuneIn Radio that might be able to deliver local radio stations without using the actual FM receiver if you have WiFi or mobile data on. When I tried it it wanted my location then offered some local radio stations.

Just buy a cheap earphones, cut the 3.5mm Jack and leave it
If there should be a magisk module that can even spoof physical port as it's connected or particularly spoof fm app that device is connected with headphone then that'd be great!

---to route on blutooth just change output(android 11+ or some custom roms) to Bluetooth
->>>reliable means always works root requires
--Just flash magisk module lsposed(zygisk version preferred) :- https://github.com/LSPosed/LSPosed/releases/tag/v1.8.3
--Than after reboot install Xposed module(apk) : https://dl-xda.xposed.info/modules/...xoverrideheadphonejackdetection_v5_547951.apk
---Than activate module choose system framwork , now you can manually change to
headset than fm start working
---and if you want to route fm to blutooth just change(for android 11+ or some custom rom) output to Bluetooth.
