AF_LTE and NPROTO_AT alternatives? (27.06.2022)

[Elias]

Hi,

I have been looking at the sample https://github.com/Rallare/fw-nrfconnect-nrf/tree/nrf9160_samples/samples/nrf9160/simple_at and see that the socket() function uses AF_LTE and NPROTO_AT, but I can't find any documentation on these identifiers. Are they outdated? If they are, what are the replacements?

Regards,

Elias

Yes, they are (assuming you are using one of the newest releases).

The AT sockets has been removed, and replaced with the AT interface in the modem library: https://developer.nordicsemi.com/nRF_Connect_SDK/doc/2.0.0/nrfxlib/nrf_modem/doc/at_interface.html

The documentation itself should be quite good, but you might also want to look at the at_monitor sample, which shows how AT notifications can be received in the application using the AT monitor library.

Best regards,

Didrik
