nRF9160 SiP custom board

You will need the nRF Connect Software Development Kit (SDK) in order to develop any firmware for your nRF9160 SiP. But we do have precompiled firmware that you can use to test on the nRF9160 SiP, such as the Serial LTE Modem. Note that this version does not support e.g. AGPS. To enable features you will need to download our nRF Connect SDK via e.g. Toolchain Manager.

Hopes this clears the confusion. Remember to search DevZone for answers, and if you can't find the answer just register a new ticket.

Kind regards,

I thought I could use the nRF9160 without any sdk, but knowing that such sdk it's been stored on the SiP, I don't have any problem using the SLM.

Sorry for the enconvenience.

Thank you so much for your help.

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

Hello,

I'm not sure I understand what you want to achieve. The Serial LTE Modem is currently the only application we have to connect AWS server using MQTT with AT commands.

Please elaborate more on what you are trying to achieve.

Kind regards,
Øyvind

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

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.

Hi Raj,

[quote userid="25014" url="~/f/nordic-q-a/89149/nrf9160-sip-custom-board/373296"]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.

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

You will initially have to program the nRF9160 SiP with the at_client sample application using the nRF Connect SDK. There is no other way to do this but to use the Nordic SDK.

Once done, then the nRF9160 will start accepting AT Commands via the UART from an external MCU. This allows you to use it only as an external modem.

Hope this answers your question?

Hello Cristina,
To 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.

Once the above is done, you can then use an external MCU to read/write AT commands via the UART to the nRF9160 and use it as only a cell modem.

Does this answer your question?
