I am using an RN-42 bluetooth module with my Arduino UNO. I have it set up now so that I can send characters from a PC terminal to the bluetooth module, and then read them back from the microcontroller via the Serial Monitor. The problem is that the characters I receive back are not the characters I type in originally. I have mapped each input character to the corresponding output character.
For example: if I type ‘A’, I get back ‘_’. If I type ‘B’’, I get back ‘/’ and so on. I have attached an excel file of the input to output map. I have the bluetooth modules, arduino, and terminals all set to a 9600 8N1 configuration.
Any help would be very appreciated.
