What is the problem?
I'm tying to set up control for two of my printers over the UART pins on the Raspberry Pi 3 and having some errors.
Connecting to: /dev/ttyS0
Changing monitoring state from 'Offline' to 'Error: Connection error, see Terminal tab'
Unexpected error while connecting to serial port: /dev/ttyS0 error: '(22, 'Invalid argument')' @ comm.py:_openSerial:1931 (hook default)
Connection closed, closing down monitor
What did you already try to solve it?
Inintially I was trying to connect via ttyAMA0 (which is no longer allocated to the UART pins 14/15)
I also needed to set proper permissions on the correct tty (ttyS0) which is no longer giving a permissions error, however now it's showing the above error.
I tried switching between baud rates (uploading different settings to the firmware and changing octoprint settings), 115200. 230400, 250000.
Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, octoprint.log
, serial.log
or output on terminal tab, ...)
