Changing at_host_uart0 to uart1 on the asset-tracker app - NRF9160

[zsn]

Hi,

I was working with ncs2.0.0 and using the CONFIG_AT_HOST_UART_1=y config command in the .prj file to change at_host uart config from uart0 to uart1 and I was able to send an at-command over uart1 to comms nrf9160 modem. However, after migration to ncs2.2.0. I noticed that that command is no longer available in this ncs version. It seems not enough to change zephyr,shell-uart = &uart0; to uart1 config in the chosen node. Because I tested this config by sending at-command after changing zephyr,shell-uart uart0 to uart1 and it didn't work but it works when I use uart0.

Is there any way to change at_host_uart in the ncs2.2.0 version?

Thank you, Kind regards.

Hi,

The at_host library has it's own "chosen" property. It does not use "zephyr,shell-uart". Instead, it uses "ncs,at-host-uart".

Please see the documentation for more information: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.2.0/nrf/libraries/modem/at_host.html#configuration

Best regards,

Didrik
