8. Parameter Configuration
Through serial port or using setting tool 'Rf-Tool', users can configure relative parameters such as
frequency, UART rate, air rate, checkout mode and so on.
It is very simply for configuration. Based on different requirement, all options can be selected visually. It
is shown in Table 2 and Figure 3.
Parameter
Description
UART area
The values are fixed at 9.6k bps & no parity check.
RF frequency
It indicates the center frequency of RF carrier
RF mode
Standard mode, Low Power mode
Lora spreading factor. Larger value means higher sensitivity but
RF_Factor
longer air transmission time
Lora bandwidth. Larger value means lower sensitivity. Recommended
RF_BW
value: 125K.
Node ID
Reserved
Only the modules with the same network ID can communicate with
Net ID
each other. It can avoid interferences from irrelative modules
It is used to set the output power of RF1276. There are 7 power
Power
levels. The 7 means the max. output power---20dBm and 0 means the
lowest output power.
Serial baudrate
It defines the data rate between RF1276 and the host
Serial parity
It defines the parity check between RF1276 and the host
