ZecTrix NOTE4C Devkit firmware v1.2.1
Fixes Front and Down becoming unable to wake the device when a button remains held as an operation finishes.
- Wait for button release before final deep sleep, using light sleep for prolonged holds. Both buttons remain enabled for the next wake.
- Preserve charging-state wake, existing refresh/setup gestures and saved Wi-Fi/connection settings. Additional presses during an active operation are still not queued as another action.
Install or update
