RF4432F27 : Comprehensive Demo Board For RF Transmitter And Receiver Modules
Users can use the Demo board to set the parameters of the RF transmitter and receiver module RF4432F27 such as working mode /frequency /transmitter power / transmission data rate through the buttons, and measure the wireless communication distance.
Working mode of RF Transmitter And Receiver RF4432F27
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.
3) The acknowledged signal after received the data from the master.
4) Tx Test Mode: RF module continuously transmit signal.
5) Rx Test Mode: RF module is always in Rx mode.
6) Standby Mode: RF module is always in standby state.
Button Operation of RF Transmitter And Receiver RF4432F27
1) [SET] Button
Press the [SET] button to enter setting mode if not in setting mode. In setting mode,press[SET]button to toggle between the set parameters: working mode /frequency/ output power / data rate / spreading factor/ Bandwidth. The related LCD ICON will flash to indicate.
2) [UP] Button
In setting mode, press the [UP] button to increase the value of flash icon.
Note: The DEMO board has FLASH memory inside, all the setting parameters will behave automatically and keep unchanged even power-off.
