Hello,
Running into an issue where it seems like some serial communication isn’t being read on the esp32 and is sent directly to the serial monitor on reset.
I have an esp32 wroom test board connected to a rs232 to ttl connector, with the rx and tx being connected to pins 9 and 10 on this board, and the vcc connected to 5V (and ground to ground). The rs232 is connected to a device we can verify is sending data (we have a splitter cable downstream with one side going to a logic analyzer). However nothing we’ve programmed the board with so far has successfully been about to ‘capture’ the data in any usable way, and the only time we’ve seen the data is whenever the board is reset or unplugged, and then we see it in the Serial monitor console which doesn’t make any sense to me. All sketches we’ve tried so far use software serial to define two of the usable digital pins as serial and we’ve tried many different pins with the same result.
We’re just curious as to why the data seems to be ‘skipping’ the esp32 and is only available on the serial monitor, and we need to figure this out for this project. Thank you.
