This is the script that can record video on webcam and play sounds simultaneously. You can play sound by pressing "Play Sound" button; to start recording you need to press "Init" button first. What I need: if there is a bluetooth speaker connected to the phone, I need the sound to be played on that speaker (not on internal speaker). It works this way until you Init and start recording. Try connecting BT speaker, then pressing the Play Sound button before and after Init - you'll see that it switches from BT speaker to internal. I need to fix that so that sound be always played on connected BT speaker. Important notes: the connected BT speaker must not have a microphone (can't be a headset) - it would work fine

I am building mobile apps for iOS and Android. I have found an old Android app online that is very similar to ours. I need someone to dig into the code to view the request/responses for a couple of different bluetooth calls. 1) Login using a PIN and 2) set a PIN. If you are interested I can send you the apk. I'll need the complete set of characters in the commands (there could be some characters in the beginning and end of the response). I'll also need to know how to read the response. I can share the app if interested. Thanks!

Hi, i have a app which controls a Bluetooth device. It works on all Android versions. But on Android 12 it crashes when i click on "ELOC Settings". You can see the code here: And a video of what happens with Android 12 in the attachment. You won't be able to test it because you need to connect to a ELOC device first in order to test the "ELOC Settings". But maybe you see something in the code which causes that issue?
