Utilizing AT Commands via SPI Protocol on the nRF9160

[Carlos Romero]

Hello everyone,

I'm working with the nRF9160 module and exploring possibilities for transmitting AT commands, with a specific interest in using the SPI protocol. Additionally, I have a setup where several ESP32 devices are serially connected and will be transmitting various types of frames. The intention is to subsequently send this data to the internet via the LTE capability of the nRF9160.

I have a few inquiries as follows:

• AT Commands via SPI: Is it possible to send AT commands to the nRF9160 module using the SPI protocol instead of UART? If yes, is there any documentation or example available that I can refer to?
• Recommendations and Examples: Based on your experiences, do you have any recommendations or best practices for implementing this type of communication? Any examples or resources would be highly appreciated.

Thank you in advance for your time and support. I'm looking forward to your valuable insights and suggestions.

As far as I know there is no direct support in the SDK for this at the moment. So you will need to implement this yourself.
