Can I use other pins instead of txd and rxd to connect to the bluetooth module?

Question

Arduino

Can I use other pins (for example D10 and D11) instead of txd and rxd to connect to the bluetooth module? Or how can I change the password for connecting to the at-09 bluetooth module via arduino nano?

Answer 1

you can connect to which port you want rx / tx from the bluetooth module, I connected to D5 (arduino) -Rx (AT-9) and D6 (arduino) - Tx (AT-9), initialization is like this SoftwareSerial BTserial (6,5) ; I'll leave this answer, maybe kamuta will come in handy, I would save a few hours of agony :D

Answer 2

If you use the SoftwareSerial library .
