Sporadic fail on readRegisters #35

Open marn06 opened 1 year ago

Hi @dkjonas

Thanks a lot for the great work you have done with this project. I am using your code with a few small changes on an ESP32-C3. Unfortunately I see sporadic fails when reading registers, is this something you also experience? See mqtt log, where POLL represents the start of reading registers on all channels: image

Hi @dkjonas I actually think I found the solution, at least I haven't had any fails for hours, with the new code in bold added: Serial1.begin(38400, SERIAL_8N1, rxPin, txPin); ESP_ERROR_CHECK(uart_set_mode(UART_NUM_1, UART_MODE_RS485_HALF_DUPLEX));

Hey @marn06

Would you mind sharing your esp32-c3 repo - and are you able to use uart directly from the esp-c3 or do you still need a max3072e? My setup with a 8266 works, but I'm having intermittent issues so I'm looking to try alternatives

Hi @Roarrk Sure, but my code is based on this board, let me know if you are still interested. https://www.ustepper.com/shop/#!/products/esphome-modbus-module
