NRF52832 with third party cellular modem

Avigdor

Hello,

I'm using nRF52832 board and I want to use it as a controller with a third party cellular modem to connect to AWS IoT. i.e. I want to send AT commands with the UART to the modem.

I saw that Nordic have examples in the nRF Connect SDK for AWS IoT and serial LTE modem and I saw that they are applicable also for nRF52.

Can the AWS IoT example be used as a controller for external third party cellular modem?

Do you have similar examples for nRF5 SDK? if so, should i use the NRF5 SDK over nRF Connect SDK?

How would you recommend developing such use case?

    Hello, 

    I saw that Nordic have examples in the nRF Connect SDK for AWS IoT and serial LTE modem and I saw that they are applicable also for nRF52.

    There is a nRF52 sample which is applicable to use with the Serial LTE Modem application, which is used to emulate a stand-alone LTE modem on the nRF9160. The nRF52 client for SLM is used to issue AT commands to the SLM application form e.g. BLE connected device.


    Can the AWS IoT example be used as a controller for external third party cellular modem?

     No, this is written for the nRF9160 cellular device. You will need to rewrite quite a lot to work with a third party cellular module. Perhaps looking at the e.g. Generic GSM modem chapter in the Zephyr repo is a better place to look? This also includes a Generic GSM modem sample.

     

    Do you have similar examples for nRF5 SDK? if so, should i use the NRF5 SDK over nRF Connect SDK?

     For our new customers we encourage starting with the nRF Connect SDK. Have a look at the Working with nRF52 series guide

    Kind regards,
    Øyvind
