Cellular Monitor 2.0 Does Not Support A Separate Serial Port

[Jared]

For a device like the nRF9160 Feather, you need a second USB to UART device for listening to the modem traces. When I go to select the Terminal Serial Port under Advanced Options, it only gives me one option (the external FTDI adapter). As far as I understand, they can't be mapped to the same interface.

Running on Linux. Will try on Mac to double check it's not a platform specific issue.

I just ran into this myself.  I can setup my monitor client firmware(Rust) to send traces at 1M or be used as an AT command driver at 115,200 baud but not both.    Using the Conexio Stratus dev kit. 

Do the supported devices really have two separate uart bridges?

What do you refer to as supported devices?

Thingy91/Nrf91 DK.  I have a Thingy91 which does enumerate as ACM0 and ACM1, but I've yet to test modem trace and serial terminal at the same time.

Hi,

It should be possible to use modem trace and serial terminal at the same time.

You're saying you can use the AT Console and Trace on the same UART interface? As far as I know you need a dedicated UART for each.

This is still an issue with any board not manufactured by Nordic that may require an external serial device for the "Terminal Serial Port"
