Yes, that is possible if you enable the AT host in your project:

CONFIG_AT_HOST_LIBRARY=y

Kind regards,

It should be possible to do debug printing and send AT commands to the modem. Could this be done with one UART interfeace?

Hi Konradin,

[quote user=""]Why UART0 and UART1 is is used by the nRF9160 on Thingy 91? Do i need both on my custom board or could I select one UART interface?[/quote]

Those UARTs can be used for your application, normally uart0 is debug prints and uart1 can be freely used.

Similar to the nRF9160-DK, we are trying to get modem tracing on uart1 to run on thingy:91 as well (this PR: https://github.com/NordicPlayground/fw-nrfconnect-nrf/pull/2058)

That depends on your application. Do you need UART? Debug printing can also be done over RTT

Kind regards,

Håkon
