nrf9160 (NRF9160-SICA-R) as modem for sending/receiving data by AT Commands

[SilasV]

Hi DevZone! 

I would like to use nrf9160 for sending/receiving data by interfacing it with my microcontroller over UART and sending AT commands. I have a nrf9160 Feather board (check here) which is flashed with the latest modem firmware. I have tested it with CoolTerm (serial terminal app) and it responds with AT Commands. Now I am looking for example set of commands which can help in sending/receiving data over TCP, this will really help a lot! 

Requesting your help/ any pointer

Thanks

Hi!

I think you are looking for the Serial LTE Modem sample in NCS.

Here is an example of how to establish and test a TCP connection, and send and receive data. 

And here is the documentation for all the supported AT commands for this sample.

Please let me know if you need anything else!

Best regards,

Heid

Hi Heidi

Thanks for your prompt reply!

I am actually new to using Segger Embedded Studio for nRF Connect. I could build the SLM application in SES and it produced merged.hex output file. How do I also get the .BIN file output which I need to load into the nRF Feather board? Sorry if I am asking a very common question :( 

Thank you so much!

Hey Silas,

I wrote up some quick instructions on the subject in the nRF9160 Feather documentation. Hope it helps!
