Perfectly working. Be aware when you open the connection with HFP profile … Use “OPEN (ADDRESS) AG” instead of logical “OPEN (ADRESS) HFP”
small powerful device, I am sure it is capable of doing everything I need to make a audio device with bluetooth. My biggest complaint is commanding the module. Manufacture support is hard to come by, documentation is incomplete and I spent way to much time learning how to make it function. I would give the module 4 stars but support maybe 1 star
A customer upgraded the firmware and had this to say:
“The issue ended up being that the newest firmware for the BC127 module (6.0.37) has a new set of commands. And several of the v5 firmware commands are no longer valid. I had updated the firmware on both modules before I started testing.”
