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

Please see this part of your output log: UART_1_NRF_UARTE (defined at drivers(serial/Kconfig.mrfx:94) is assigned in a configuration file, but not user-configurable as it has no prompt. It gets its value indirectly from other symbols. See "">docs.zephyrproject.org/.../CONFIG_UART_1_NRF_UARTE.html"  or look up UART_1_NRF_UARTE in the menuconfig/guiconfig interface for more information.

Best regards,

Simon

Hi,

so i added this in my kcong file :

"config UART_1_NRF_UARTE
    bool
    default n
    select NRF_UARTE_PERIPHERAL
    depends on UART_NRFX && SERIAL
    help
      Enable nRF UART with EasyDMA on port 1."

Did I understand right ?

Now i have no problem to open and reload my project.

UART1 isn't see like a port COM now, wich it is a good news but i see nothing in my external port by a terminal Putty. So did i miss something else ?

Best Regards
