DESCRIPTION

DRF1276DM is a type of long range low data rate data radio modem based on SX1276 from

Semtech. DRF1276DM is a low-cost sub-1 GHz transceiver module designed for operations in the

unlicensed ISM (Industrial Scientific Medical) and LPRD bands. Frequency spectrum

modulation/demodulation, multi-channel operation, high bandwidth efficiency and anti-blocking

performance make DRF1276DM modules easy to realize the robust and reliable wireless link.

The module can work in two different modes: Standard mode and Star network mode. In the

standard mode DRF1276DM acts as transparent data radio modem which it communicates with

the host at the preset data format without encoding / decoding needed. In start network mode, one

module will be the configured to the central module and other modules are set to node modules.

The communication between the central module and node module are bidirectional but the node

modules can not talk with each other.
