What is the problem?
When I try to connect from Octoprint 1.4.0 to my CR-10 S5, it gives an error:
Changing monitoring state from "Detecting baudrate" to "Error: No more baudrates to test, and no suitable baudrate found."
What did you already try to solve it?
Tried changing the port to /dev/ttyAMA0, also tried to change the USB cable which changed the behavior a bit like below:
2020-05-26 18:08:22,168 - octoprint.util.comm - INFO - Changing monitoring state from "Offline" to "Opening serial port"
2020-05-26 18:08:22,178 - octoprint.util.comm - INFO - Changing monitoring state from "Opening serial port" to "Detecting baudrate"
2020-05-26 18:08:23,195 - octoprint.util.comm - INFO - M110 detected, setting current line number to 0
But ended up the same way.
