LoRaWAN communication interface:
Using LoRaWAN communication for meter reading and parameter setting. When meter reading, remote meter data transmission software provided by our company can be used for meter reading and parameter setting. It is also possible to design a software and hardware system that fully complies with the protocol requirements for meter reading and parameter setting according to the power industry standard DL/T 645-2007 (supporting part of the communication protocol).
Please take attention to the following points when handle meter reading and parameter setting:
a. Parameter setting, please just setting items which refers to the certain meter.
b. LoRaWAN active upload data format:
