7 LoRa Bit Rate

7 RF bit rates (10000, 6000, 3400, 1800, 1000,
500, 250 bps)

The maximum supported RF receive sensitivities
of each baud rate are listed below.
Baud rate (bps)
Max. RF Receive
Sensitivity (dBm)
10000 -120.0
6000 -123.0
3400 -126.0
1800 -129.0
1000 -131.5
500 -134.0
250 -137.0
8 RSSI information

Enable or disable the COM0 port to add “RSSI
(Received Signal Strength Indicator, positive
number)” and “SNR (Signal-to-noise ratio, 2's
complement)”, 2 bytes RF signal information, at the
beginning of the received LoRa data when
receiving a valid LoRa message.
SNR RSSI
SNR byte >= 0 RSSI = -157 + (16/15 * RSSI byte)
SNR byte < 0
RSSI = -157 + (RSSI byte + SNR
byte * 0.25)
9 RF Output power

Value 0(0) ~ F(15) are mapping to the RF output
power range of 0 ~ 15 dBm.
Step 7: Press the save button to save all device parameters into module
Step 8: After setting, switch the RFU-900 “Init.” switch to “Off” position and reboot
the module.
