Hi, I recently try to build a bluetooth controlled R2-D2 robot with a speaker built-in. I had mechanical part done already, and I tried to control it with adafruit BLE module. It works, but it will only be cool with a speaker inside of it. I found the CSR8645 bluetooth chip is a very powerful which have port for speaker output, volume control, and serial port as well.
However, I can’t find any post about this chipset on the forum. Is there anybody have tried this chip communicate with an arduino UNO yet? How can I use my phone control the motor and play music at same time? or any suggestion of using other chip?
Thank you very much!
