Switch on powerthe microcontroller will configure the RFM module according to selected parameter. 3. RF DEMO start to send out data packets with one second interval . 4.When the Master module have one transmission, the TX LED will blink once to indicate the transmission. If the Slaver module received the data packets and verified to be correct, the led on receiver will blink once,and the Slaver will reply same packet data to the Master,The TX LED on the Slaver will blink.When the Master received the data packet and verified to be correct,the RX LED on the Master will blink. Carrier testing: When the test mode select 11, the module enter into carrier test mode, The working frequency and power of module can be measured by the spectrum analyzer. Sensitivity: When the test mode select 10, the module enter into the sensitivity test mode, the module can be directly connected signal generator,then the receiver sensitivity will measure. Precautions: 1Power supply range from 1.8V--3.6V 2 Dip switch setting for TX and and RX setting must be matching with each other. 3 Once a different setting is needed, make sure to re-power up the system again to make the setting valid.
