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
Disabling flow control has fixed the issue. It may be good to add that as an option in the app.
I was running on 1.2.0 of the SDK. Tried 1.3.0-rc1 with no success. I also tried to connect via a Windows VM with no luck. I'll try a completely different machine to confirm it's nothing weird here.
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!
I will report this internally as a bug. Thank you for reporting, and good work on finding the root cause!
Can you share how you disabled flow control in LTE Link Monitor? How and where did you modify the index.js file?
Here is what I did:
