nRF91x1 SiP LTE firmware 

Programming app available in nRF Connect for Desktop

Selected version
2.0.1 nRF91 firmware binaries

Changelog:

2.0.1 nRF91 firmware binaries

This release support nRF9131 LACA A0, nRF9151 LACA A0, and nRF9161 LACA A0 SiP.

This release does not support nRF9160 SiP.

Highlights: 

General

  • Added support for the nRF9151 LACA A0 SiP module.
  • Added support for IMEI read, write, and test operations through nRF Util development tool.

Cellular IoT

  • Introduced support for power class 5, enabling a 20dBm TX transmitter mode with nRF9151.
  • Socket option for power optimized way to resume data transmission after PDN disconnect and connect procedures. 
    • This feature is particularly useful for DTLS + CID and UDP connections.
  • Enhanced network selection optimization during initial search.

Location services / GNSS

  • Improved fix accuracy and availability in periodic fixes when the fix period is 60s or less.
  • Updated speed and altitude operational envelope limits for dynamics modes to further reduce possible GNSS outliers.
  • Updated QZSS health data handling to match IS-QZSS-PNT-005.
  • Addressed modem instability when GNSS 1PPS functionality was turned on/off repeatedly.

 

A complete list of new functionality, changes and bug fixes is in the release notes found here or inside the .zip file.

This release is aligned with v1.1 of the nRF91x1 Cellular AT Commands Reference Guide.

Some of the new features requires support also from the nRF Connect SDK.

It is recommended to use the latest version of nRF Connect for Desktop and nRF Connect Programmer tools.
