My assignment is to transfer data wirelessly from one microocntroller to another ,to prevent interference my lecturer suggest me to use a specific address of xbee means that i only transmit to a specific microcontroller since a specific address of bluetooth is used. But suddenly i have a crazy idea, what if i assigned different baud rate to different microcontroller ? Then let say like if i want to connect to microcontroller a i will swtich the baud rate to be same with it, wil it works? Difinitely it is much easier than changing the address of the bluetooth device.

 

Just changing the baud rate of one device won't prevent it from receiving data. If it can receive data it will just receive garbage.
