Hello,

I have question. Do You have any document which describes CSR8645 uart commands? I am developing some receiver and want to communicate CSR8645 with mcu.

Datasheet of CSR8645 not have any uart commands, i think uart used only for test and debug features

But there should be some bluetooth AT commands I think so... :/
