![]() ![]() I'm trying to replace the serial cable with the bluetooth module but when I send data from the ST board I recieve strange characters in hyperterminal (triangles, question marks, faces)? I'm just looking for any advice on this problem, I've checked all board rate settings on device and hyperterminal and my STM32F4 program but still no luck. The discovery board transmits data over serial cable ( rs232 ) to hyperterminal fine. I have paired with the module and can use the get/set commands to communicate with the device with no problems. I am using hyperterminal on windows 7 to talk to the RN-41-sm module which is connected to an STM32F4 discovery board. ![]() ![]() Rn-41-ms bluetooth module communication issue with hyperterminal ![]()
