Typical application circuit


Working Mode:

1) Master Mode: Send 1 packet per second, and waiting for the acknowledge;

2) Slave Mode: Stay in Rx mode to wait for the data from the master, it will send back the acknowledged signal after

received the data from the master.

3) Tx Test Mode: RF module continuously transmit signal;

4) Rx Test Mode: RF module is always in Rx mode;

5) Standby Mode: RF module is always in standby state.


Button Operation:

1) [SET] Button
