I’ve followed the various directions (e.g. Disable console over Serial in Dev on RPi3? and https://github.com/resin-io-playground/rpi3-uart/blob/master/main.js), and I’m able to receive messages transmitted from the rpi but I’m not able to receive messages to the rpi.
- using screen on both my Mac and the rpi, as well as Coolterm on my Mac
- changing the baud rate right down to 1200 (default for testing has been 9600)
- confirming the serial is working with a standard Raspbian disk image (so have ruled out hardware/connection issues)
- run the test script at https://github.com/resin-io-playground/rpi3-uart/blob/master/main.js (write works fine, but I don’t see any received messages)
(I’ve set the config variables via the fleet options, not locally to the device)
Is there anything specific that might cause the receive not to work while transmitting is ok?
Thanks in advance.
