LTE Link Monitor timing out

[Jared]

Hey All,

I'm running the LTE Link Monitor on nRF Connect 3.3.3. I'm connecting to my custom nR9160 Feather via the built in USB-to-Serial. I'm able to open the serial port in LTE Link Monitor. I hit the reset button and it shows the boot dialog. But when I tried to send commands, it doesn't respond.

While, if I try to connect via something like Cool Term I can issue AT commands without an issue.

I'm running on OSX 10.14.6

Ahh, I think I found the issue. Flow control is set active for modemtalk

My board doesn't have RTS and CTS to the USB-to-Serial! So that would solve that problem!

Disabling flow control has fixed the issue. It may be good to add that as an option in the app.

I will report this internally as a bug. Thank you for reporting, and good work on finding the root cause!

 

Kind regards,
