nRF9160 proprietary AT commands (ie AT%CMNG=1) via firmware functions?

[JonnyMN]

I want to be able to send the "AT%" type of Nordic proprietary commands to the modem (and read the response back) via firmware on the nRF9160. I know about the 

nrf_modem_at_cmd(), however that only supports "AT+" type commands, and all "AT%" type commands results in an error message response.

How can I send and get the response for "AT%" type commands in firmware?

Thank you.

Hi,

 

How are you sending the command to the modem? "%" needs to be escaped in C, whereas you normally escape with "\", you handle percent a bit different: https://stackoverflow.com/questions/1860159/how-to-escape-the-percent-sign-in-cs-printf

 

Here's an example of a formatted string from lte_lc.c:

https://github.com/nrfconnect/sdk-nrf/blob/v1.9.1/lib/lte_link_control/lte_lc.c#L81

 

Could you try this and see if it works better?

 

Kind regards,

Håkon

That fixed it! Thank you!
