RE: LTE modem validation / firmware testing

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,
