RevPi Connect no /dev/ttyRS485 device
Posted: 14 May 2019, 17:22
Hi.
We are making a solar tracker with one RevPi Connect and a DIO module. All works OK but today the /dev/ttyRS85 symlink disappear:
This is related to /dev/ttyConBridge
This is /dev/ttyRS485:
There is only one /dev/ttyUSB* device:
Any ideas?
