v3.3.8.dev1 (non-U devices)

OTA updates not working

What happened?

Starting with v3.3.8.dev1, OTA updates do not work on non-U devices.

Due to a bug, native OTBR support was enabled for non-U devices, which resulted in low available RAM values. Due to the low amount of available RAM, the device can no longer perform HTTPS requests, so OTA updates via our update server no longer work.

Solution

You need to update your device locally.

1. Download the update file from this link https://updates.smlight.tech/firmware/slzb06x/core/slzb-os-v3.3.8.dev5-ota.bin
2. Go to the menu "Settings and Tools" -> "Firmware update"
3. Select "Flash the custom firmware" for "SLZB-OS Update"
4. Select downloaded update file and press "Update firmware"
5. Wait for the update to finish
