The module can work in two different modes: Standard mode and Star network mode. In the standard mode It 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 node 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. Please note that the 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.
RecommendUSB to TTL Converter to set the module parameter, andGravity IO Expansion Shieldcan directly work with the Lora modules.
