Hi,

can someone confirm that there's an issue with the URCs on SARA-R412M or am I just missing some setting?

If DTR signal is not asserted (set low) then URCs are suppressed. This may be the issue.

Thanks! This solved our problem. There was a missing resistor on our board that caused DTR line to be high.

Do you have hardware connection on UART pins as described in u-blox manual?

You may need to talk to u-blox directly about this.
