KerOS firmware v5.9.0 (June 2023)
Changes from v5.7.2
Release corrections
- Fix lora_snmp iptables rules management
New features
- Offer a menu in WebUI to retrieve logs from a gateway
- Display a cellular signal quality indicator in WebUI
- Offer a Router mode : a GW with a cellular backhaul shares its internet connection to other GW connected in ethernet.
- Support of a new WAN modem certified with Softbank in Japan for the iFemto-evo 923
Evolutions
- Monitor “lorad” daemon and trigger a reboot when process is unstable
- Make it possible to set/get a generic operator by SMS
- Delay connection activation attempts in connman
Restrictions
- IPSec is not yet supported
- Some issues with the Wi-Fi interface (instabilities, no fallback…) on Wirnet iFemtoCell
- When upgrading from KerOS firmware 4.x, all trustzone secrets are lost
- When upgrading from KerOS FW 4.3.3, a hardware reset is necessary for FW 5.x burner to correctly detect USB
- Update status for an update from KerOS FW 5.1.x, FW 5.2.x or FW 5.3.x is in error, but the update is working fine
- No more support of GSM dongles (please contact Kerlink if you plan to use one)
- When iZepto-E is powered by a computer, it cannot benefit from the connection of a gateway in router mode
- The activation/deactivation of the GSM from the local web interface takes some time to execute, so previous activation status remains displayed for a while. A page refresh after a delay of 15-20s after the action shows the right status
