Is there any AT commands library for nRF54L15

We aim to use an external Cellular module for MQTT communication.

I found that the nrfxlib/nrf_modem library ‌is only supported‌ for nRF9x series MCUs. Does this ‌support‌ the nRF54L15? Otherwise, is there any library in the SDK that supports AT commands?

  • Unfortunately No. The AT library is made as a binary which only works for nRF9X devices. If you are using nRF54L, then you should probably send the AT commands through UART to your external modem which parses these commands for you.

  • Hi Susheel,

    Got it, thank you very much for your reply.

    Please correct me if my following understanding is incorrect: The nrfxlib/nrf_modem library is used for a MCU(nRF9x) which is used in a CAT.M module. This application scenario is opposite to my application scenario.

    Yes, you are right, and you cannot use this lib if you are not using nRF9x product.

    I assumed that your external modem supports AT commands and I was suggesting to use UART_on_nRF54L15->UART_on_external_modem.  But if your external modem does not have UART (which it seems that it does not have) then my suggestion will not work for you. 

    Probably it might help if you can tell which external modem you are using so that I can checks its capabilities and support of any other commands that can be parsed/encoded into AT commands
