For a project I am looking for an Audio Bluetooth Module with full-featured serial control support, such as AT commands.

I was able to get three different modules based on BK8000L, BK3254 chips. Only one module worked with AT commands and that was the defective firmware.

Interestingly, the sellers themselves don't really know what they are selling. I contacted, it seems, with reputable Chinese manufacturers, but they produce conventional options with button control.

If something came across such a question and can advise where to buy, I will be grateful.

Hi,

in the past i used a Laird BTM511 module for voice connections and it worked well but unfortunately now it is NRND.

Now BLE 5 allow audio connections and most manufacturers stack support it. You can look at Silicon Labs modules based on their BLE 5 chips. They offer a free development system that allows an easy development of an AT command shell.

Regards
