Update Modem Firmware - Bolt2

It is possible to update the Nordic nrf9160 modem firmware over the air. 

Things to consider:

  • Modem firmware cannot be downgraded!
  • Many networks approve specific modem firmware versions - not always the latest. Ensure you check which version is approved for use on your network before upgrading!

Upgrade Process

  • Ensure your main device firmware is set to 1.3 or above
  • Edit your admin parameters
    • Enable Modem Updates = Yes
    • Select your desired modem FW version

Devices are shipped on 1.3.0. This is the approved version on some networks, and given downgrades are not possible - this is what is required. This allows all users to set the required version by either leaving as is on 1.3.0, or updating while provisioning devices.

Which version am I currently on?

This can be seen on the device details page in OEM Server

A 'Modem Version' column can be added to the grid to view many devices at a time. 

  1. Click Select Columns
  2. Field chooser will open, drag Modem Version into the Grid
