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, central mode and node mode

RF_Factor

Lora spreading factor. Larger value means higher sensitivity but longer air

transmission time. It only can be changed by users in standard mode

RF_BW

Lora bandwidth. Larger value means lower sensitivity. Recommended value:

125K. It only can be changed by users in standard mode.

Node ID

It is only used for node modules: 0~65535

Net ID

Only the modules with the same network ID (0~255) can communicate with

each other. It can avoid interferences from irrelative modules

Power

It is used to set the output power of DRF1278D. There are 7 power levels. The 7

means the max. output power---20dBm and 0 means the lowest output power.

Breath

The wake-up period for node module. Only available for firmware 2.0 or above

Wake timer

The time for detecting wireless signal during breath period, only available for

firmware 2.7 or above

Serial baudrate

It defines the data rate between DRF1276DM and the host

Serial parity

It defines the parity check between DRF1276DM and the host

Table 5: DRF1276DM Parameter Table

Please note that the preconditions for two or more modules to communicate are that the

frequency, RF factor, RF_BW and Net ID must be the same.
