nrf24l01 communication encoding

[ketanrathod]

I am using two nrf24l01 in my project at both end for wireless communication between both. If I uses more than two such devices, how should I encode it for multiple devices ?

Without ACK you can send a package to all devices with similar initialization code.

I want to avoid interference between more than two two devices. So how should I do ?

you can do it by implementing RS485 type communication protocol to your RF communication (UART)means every device recognize with its ID for example say 1 to 255 so if you want communicate with device 1 send data with starting with device id 1 and your data.

I have no idea what common between RS485 and NRF24L01. NRF is a package receiver/transmitter. It can send a packages with variable lenght 1..32 bytes without any waranty of beeing received as it is a wireless communication device. So, if you want to build a network, you will have to design your own protocol.
