Bluetooth Audio Modules

[Obi_Kwiet]

I'm developing a communications system for my powered paraglider. I'd like to use wireless audio links between various system components. I like to avoid wireless if possible, but in this case, I think the safety benefits are compelling.

I don't have much experience with bluetooth, and I was hoping to get some perspectives on what modules are have the best support and documentation for beginners. I've got some requirements that might be a hassle. First, I have an IO unit that connects to several analog radios, and I'd like a two way wireless audio link between it and my helmet. I'd like to be able to switch between A2DP and Headset profile, because this unit will have an aux input.

I'd like the headset to simultaneously be able to connect to a cellphone. It should be able to reliably switch between audio streams from the analog IO unit and the cellphone. I also need to pass occasional commands between the headset master and the slaves. I'd also like to be able to get some control commands to and from additional BLE slave modules.

Can a single Bluetooth master reasonably handle all of this reliably? Do you think Bluetooth is reasonable here? Are there any good resources for learning how to juggle profiles like this?

So far I'm looking at either an ESP32 or something from Si Labs or Cypress. I'd like to use the on board SoC as my micro.

Thanks!
