Hello! I'm interested in brain computer interface and brain cognition. I'm going to do a multi brain computer interface experiment. I spent a lot of money and time to make 10 printed circuit boards, but upload firmware error! The problem is the RFD22301 Bluetooth module.
Is the Bluetooth module I bought fake?
But I bought them from three suppliers, none of them can.
This Bluetooth module is less used and expensive. No one wants to imitate it, right?
