Hello, I followed your STM32 example to port nanomodbus to the STM32F103 microcontroller, and then tested it using the Modbus Poll master software, but it keeps showing a timeout error, and it’s never correct. Could you turn the STM32's nanomodbus into a complete example? I noticed there is a bug in this example! Can you help fix this bug?

Your code have been implemented modbus client (modbus master) and the modbus poll is master simulator as well. It looks like you check your configuration first.
