（二）Operation and Applications

1. Modulation mode

HM-TRLR series transceiver module can work with the traditional FSK/GFSK modulation mode, also can

work in LoRa modulation mode. The user according to the application requirements, can easily switch in

modulation mode. Use principle need large quantities of data use FSK/GFSK modulation; The occasion of long

distance transmission is required, use LoRa modulation.

2.Work mode

HM-TRLR series transceiver module has three work modes: running mode, configuration mode and sleep mode.

When the module work in the running mode, the user can send and receive data. When the module work in

configuration mode, the user can according to his requirement, through the AT command to change configuration

parameters. Sleep mode module into low power consumption mode.

Running mode timing scheme

Attention: During the modulation mode in LoRa receive buffer is full,the STATUS will lower the output to prompt

the user.
