应用范围:
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 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. DRF1276DM module doesn't contain lorawan protocol. Therefore the star network feature of this module is used with itself protocol so it is not compatible with lorawan.
