Welcome to our new KerOS documentation !
Here you will find all the information you need to get started with your Kerlink gateway running under newer KerOS versions (6.x).
We will guide you through your first steps with reference documentation and samples up to learning how to get started on major LoRaWAN use cases thanks to our demo guidelines.
You may start by checking what's new below and then jump to the First Steps.
¶ What's new ?
¶ ⚠️ Hardware / Software Dependency – Wirnet™ iStation
As part of component obsolescence management for Wirnet™ iStation gateways, specific KerOS versions are required to ensure full hardware compatibility.
Affected devices must run KerOS version 6.4.3 or later, or KerOS version 5.12.5 or later.
Devices impacted by this requirement can be identified using the following criteria:
Wirnet iStation 868 Only Serial Board ID contains one of the following strings:
CHj, CHk, CHl, CHm or any later versionProduct EUI matches one of the following patterns:
7076FFxxxx0Cxxxx
7076FFxxxx0Dxxxx
Wirnet iStation 915 MHz only with Serial Board ID contains one of the following strings: CGi or any later version
Wirnet iStation 923 MHz only with Serial Board ID contains one of the following strings: CFj or any later version
It is mandatory to verify these identifiers before performing any deployment, upgrade, or maintenance operation, to ensure that the installed KerOS version is fully compatible with the hardware.
