Hi Kincony,
Many thanks for the information in this thread.
I ordered and received new RS485 converters.
I also utilised the same software application you had used so it was simple to replicate your test setup.
The setup was straight forward and code loaded correctly as noted earlier.
Unfortunately the system did not work and failed to provide return.
Again checking using the oscilloscope the KC868-A2 board did not show a transmit signal at the output of the P6. The transmit signal is present coming from the ESP32 from IO32 and can be measured at U8 input but does not display on the RS485 output.
I can tell you that there is no output from U8 to the P6 header. This is shown by no response on the UART Assistant UI.
Please advise.
