Communication:
it is necessary to configure the RFC, DVID, and RFID that need the communication module to be the same. The module and the module can communicate. When the module comes out, the parameters are all unified, and the user can configure it according to its own needs.
AT instruction instructions:
Specifically, the JDY-40 module needs to add the ending symbol rn to send the AT instruction.
