How to configue an external UART from nRF9160 dk ?

[Zita25]

Hi,

I use the app "asset-tracker", and i would like to configure an external uart to connect a sensor to the board.

I modifed the code but i can't detect any new COM from the device manager.

Here, what i made like modification :

in the nrf9160dk_nrf9160ns.dts file :

in the main.c file :

I think the problem comes from the file prj.conf, all modifications i made in it, crash the app ... so i don't know what to add ...

I hope someone can help me

Best Regards

Zita

Hi

Yes, there are in total three COM ports from the nRF9160 DK, but only two of these (VCOM0 and VCOM2) are connected to the nRF9160 chip, sorry about the confusion. For details on routing VCOM0 and VCOM2, please see the nRF9160 DK board control on page 19 of the nRF9160 DK user guide.

As for the create_nordic_project.py failed error you are seeing, this is occurring when trying to set up a project in SES, correct? Can you show me a screenshot of the nRF Connect Options window before you press OK and this error occurs?

Best regards,

Simon
