The content of this package is listed below:

There are 3 ways to update your gateway's software:

• by using the Magic link
• by using an USB stick
• over WMC dashboard, by using the Drag and drop feature

The update procedure uses 1 USB stick will upgrade the firmware to KerOS 3.6 and will install all other packages with the required software release: BSCC, SNMP, Common Packet Forwarder (CPF) and OpenVPN packages (see the version numbers above).

1. Deflate twice the tar.gz file on the USB stick in the root directory
2. Copy files located in the folder AUTO_DEPLOY_WISTA_3.1.8_USB_STICK to the root directory
3. Add your OpenVPN secrets packages in the /vpn_packages/ folder before plugging the stick into the system (if necessary ask for packages to the Kerlink support team)
4. Plug the USB stick in the gateway USB slot
5. Wait the end of the update

Refer to the specific wikis to get more details (ex led management) about software update via USB sticks:

The USB tree should contains the following files/folders:

Main changes regard to the 3.1.6 embedded software are listed below:

• Change the embedded CPF version from 1.0.9 to 1.1.8
  • [New features]
    • Improve RSSI measures (by taking into account antenna gain/insertion loss, even in sniffer mode)
    • Improve logs
    • Improve configuration parsing (and simplify default configs)
    • Update JAPAN configuration
  • [Correction]
    • Improve stability with Backhaul disconnections
    • Improve compatibility with various LNS
    • Fix few issues regarding GPS (CPU leak issue in a few cases, failure to start lorad without GPS).

Please note that, if gateways use public IP, it also makes your gateway accessible from Internet on open SSH or HTTP ports (protected by passwords). Kerlink so recommends changing passwords as described in Connection, login and credentials
