The baud rate has been able to successfully change but still no luck in communication.
I tried blueToothSerial.begin(9600) and blueToothSerial.begin(19200) after using blueToothSerial.print("\r\n+STBD=9600\r\n") to change the baud rate. Both connected, I saw this text on my phone in the ‘Bluetooth SPP’ app after resetting arduino:
+STWMOD=0
+STNA=ArduinoBTSLave
+STOAUT=1
+STAUTO=0
+INQ=1
Then I can type text from my computer to my android but not visa versa. When I type text in the Bluetooth SPP app and click ‘Send’, nothing happens. I’ve tried using Amarino too, no luck.
I don’t understand!
