* Expose libmodbus's flush command to ModbusRTUServer API * This command proved to be necessary for stable operation for large reads at low baud rates on the RP2040. May be...
Hello! I am successfully using this library to implement a sensor device with 24 holding registers which can be read. This all works beautifully at higher baud rates. However, at...
The documentation of return values in ModbusServer.h for configure functions are reversed from the actual source code. This error then shows up in the Arduino Reference site. Comments in `src/ModbusServer.h`...
I have developed an application using yaacov ArduinoModbusSlave via RS485 serial That library requires the program allocating the array of data structures and then using a union to link the...
```text WARNING: library ArduinoRS485 claims to run on samd, mbed_portenta, mbed_opta architecture(s) and may be incompatible with your current board which runs on renesas_uno architecture(s). WARNING: library ArduinoModbus claims to...
Hello! Great library. I'm trying to get up and running on a RP2040 (raspberry pi pico) to make a very low cost solution using this library and RS485. For hardware...
When sending broadcast message (as per modbus spec to server ID 0) the endTransmission() blocks and timeouts, the function returns failed even though all the servers successfully receive the transmission....
I have a project where i am trying to connect multiple clients to one Modbus TCP server. However the current library does not support one server having multiple clients, So...
I can request reading input registers from a single slave and it works fine, even when it times out. When I use multiple slaves, and they time out, the other...
When implementing Modbus RTU on an Opta Finder, with the classical Arduino IDE, in order to read coils on a remote slave (server), we must use the following method :...
