[LTE Link Monitor] Custom serial interface not detected on macOS

[Jelmer]

LTE Link Monitor doesn't seem to be able to detect any serial interfaces on macOS that are not the DKs (or don't have 3 serial ports)

See this hacky implementation: https://github.com/NordicSemiconductor/pc-nrfconnect-linkmonitor/blob/f0194e9d6292ddc20d6d8336af87e23d646ef061/index.jsx#L69

It'd be nice if this could get fixed so the LTE Link Monitor can also be used with a custom board with generic serial interface. (on macOS)

The "auto device/port filter" option doesn't make any difference.

I can also file issue in on git if preferred.

Thanks!

Hi!

Thank you for notifying us about this. I agree that it's not ideal at all and I will take it up internally, but it's appreciated if you post the issue on GitHub aswell. 

Best regards,

For anyone ending-up here after a google search: the issue seems to be that cheaper USB serial converters don't report a serial number, which makes NRFConnect and LTE Link Monitor not list them. 

This is a non-fix on the Nordic side, so you need to get a different USB interface. FTDI ones seem to report a serial number just fine, cheaper Prolific ones seem to not report a serial number.

Thank you for reporting this, Jelmer! Glad it was sorted out.

I'll close the issue then.

Best regards,
