2 Arduino BT device communication
we have 2 arduino bt modules. try send digital input data taken 1 device through bluetooth such other device receive message , set necessary digital out ports high.
first of connected device (tx) laptop entering ther necessary password "12345" , automatically com port assigned. necessary coding while push switch bt send "1" serial port.
later connected other device (rx) laptop , completed same steps above. coding while send "1" laptop through serial monitor set led mode high.
after step removed laptop , tried send "1" while pressing switch in tx module , tried turn on led didn't work.
the reason might handshake protocol between 2 bt modules.
because both of them want necessary password "12345" start communication each other. question is possible start communication between 2 arduino bt modules.
and while initilazing bt there code this
serial.println("set bt pagemode 3 2000 1");
serial.println("set bt name arduinobt");
serial.println("set bt role 0 f 7d00");
serial.println("set control echo 0");
serial.println("set bt auth * ");
serial.println("set control escape - 00 1");
serial.println("set control baud 115200,8n1");
do have tke make changes start communication.
