I'm working with Arduino mega 2560 and HC05 Bluetooth module. I'm facing an issue that is I'm not able receive HC05 data to serial monitor. I think there is issue with Tx&Rx(0,1 pin) of board. Bluetooth module working fine with Uno and Nodemcu.
Also Mega pin 0 & 1 working fine as digital pin i/o but not working for serial communication.
And also Now able to upload code to Mega while Rx & Tx pin connected to Bluetooth module without any error, which this is not expected, why any idea?
Anyone have faced this issue, please help?
