Topic: bluetooth serial communication using hc 05 (Read 1 time) previous topic - next topic


I am trying to do Bluetooth serial communication using two hc05, I have made one as master (by assigning the role as 1) and other as a slave ( role = 0).  By using the AT+BIND command I have paired them. Now i am trying to send data using the serial monitor of master and want to read the same msg at the serial monitor of slave, but I am only getting (-1) on the receiver side.

Which Arduino ?

Which sketch ? use code tags ( </> ) to post it please.

BTW I doubt if thats alll yous sketch's contains that it will work as you are simply trying to read at the PC end not the BT points.

It may not be the answer you were looking for but its the one I am giving based on either experience, educated guess, google or the fact that you gave nothing to go with in the first place so I used my wonky crystal ball.
