nRF9160 SiP custom board

[Cristina]

Hi,

I want to use the nRF9160 SiP to connect via NB IoT to AWS IoT server but I don't want to use any SDK, I only want to use AT COMMANDS, there is some process that I could follow?

I've been using the nRF9160 DK and programmed the SLM sample to connect to AWS server using MQTT AT commands, if I want to implement such sdk where does the program been stored? on the SiP or do I have to program it on another module?

Hi Raj,

o run or accept external AT Commands to the nRF9160, you will initially have to program the nRF9160 SiP with the Nordics at_client sample application. And of course, to do so, you will have to use the nRF Connect SDK. The firmware will then reside on the nRF9160 that will accept the AT commands and execute them.

If I want to use SLM sample, wil happen the same thing?

If not, could you send me a routine to follow to connect to AWS IoT server only using at commands?

Yes, I forgot about that. Yes, the Serial LTE Modem (SLM) application should do the same.

I have actually not tested or played around with connecting nRF9160 to the AWS broker. Luckily, nRF SDK has an aws_iot example for that.

You might have to follow that to see how it initiates and connects to the AWS broker. Then apply the same AT+COMMANDS in the SLM to establish the connection.

Nordic team might be having a better answer to this.

Thank you very much, I understand better now how to implement my custom board.
