LTE modem validation / firmware testing

[venkatesh dyagala]

Hi Team,

We are using nrf9160 DK and we are new to begin this, We updated modem firmware using programmer, Now we would like to test the modem firmware.

So here are my questions

1.  How to test the LTE modem software validation 
2. How to test the LTE bands (As we are using the DK from USA, we would like to test the bands which we connected and we would like to connect)
3. How to test LTE security mechanism validation

Please let me know the procedure with available documentation

Thanks,

Venkatesh

Hi Venkatesh,

This can be done by flashing the AT Client sample (also included in the FW .zip) and use the LTE Link Monitor to issue AT commands directly to the modem. 

All the supported commands are located in AT command reference manual.

You can check the band you are connected to, and also lock to the bands you want to connect to etc. (e.g. by using AT commands) as long as you have the correlating SIM card so the network can allow you to attach to the network on that band.

Please check out the additional information in the whitepapers:

• nRF9160 Hardware Verification Guidelines
• nRF9160 Antenna and RF Interface Guidelines

Best regards,
