Modbus - communication protocol is based on the master-slave architecture. It uses RS-485, RS-422, and RS-232 interfaces, as well as Ethernet TCP / IP networks (Modbus TCP protocol) for data transfer. The Modbus RTU message consists of the address of the SlaveID device, the function ...
Modbus: enhanced sstclval, ssstep, ssfixed to better support floating values. Modbus: added support for ssflstep and ssflrandom to generate floating point numbers. LoRa: fixed issue with cloning of OTAA devices. Modbus: added support for SA_mbus_setbigendian and SA_mbus_getbigendian to con...
