KerOS firmware v5.10.1 (October 2023)
Changes from v5.9.0
Release corrections
- Fix missing channels in LoRaWAN radio configuration
- Enable LoRaWAN radio configuration by Basic Station on iZepto-cell products
- Monitor temperature range at LoRa service start
- Reduce RAM consumption caused by internal databases
Evolutions
- Add the possibility to use HTTPS for the Web User Interface
- Support of EC25J auto-Fuota
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
