Sending music from Atom Echo (ESP32) to Ubuntu VM. #557

Problem Description

Hello ! First, I would like to thank you for this wonderful repository !

I'm attempting to flash my M5 Atom Echo (ESP32) with the "bt_music_sender" example to stream music to my Ubuntu VM (22.04) on which there is a bluetooth dongle connected. I've set my ubuntu VM so that it can act as an A2DP sink by following this tutorial. Once configured, I can listen to music on the VM when i stream audio through my phone.

But when i attempt to stream "music" by using the "bt_music_sender" example, i'm not able to hear anything 🤔.

I'm quite a noob, so I'm really sorry if I've misunderstood a step or any kind of information that might help me to stream music.

Here are some logs :

Other Steps to Reproduce

No response

Provide your Version of the EP32 Arduino Core (or the IDF Version)

2.0.14

I have checked existing issues, discussions and online documentation

I have never tried this and I don't think that I will be able to provide some support for linux There are no errors reported from this library, so what are the error messages you get in the Linux log ?

I suggest that you also add some log statement to your callback, to verify if it is called to confirm that we are sending any data

Hi @pschatzmann,

Thank you so much for your help. I successfully got everything working a week ago, but I've been too busy to update you until now.

In a few days, I plan to post a GitHub repository detailing how I got my "Atom Echo" to function as a Bluetooth microphone, using your repository as a reference. It will include instructions on how to have it recognized on Linux machines (specifically Raspberry Pi OS on a Raspberry Pi 5) as an A2DP-Source, allowing voice data to stream directly to an STT engine in Home Assistant.

If you're interested, I'd be happy to keep you informed.

Have a great day ! @xG3nesis
