DWARF II OTA Firmware Update TutorialUpdated 15 days ago

1. Attention

To improve the overall interaction experience of the DWARFLAB app, please upgrade the firmware before shooting.

**The logic of OTA Update:

1. Connect to your DWARF II first, the app finds its current version(of the telescope) when connected with DWARF II.
2. Disconnect the App from DWARF II's WiFi, and let the app have access to the Internet to download the updated firmware files.
3. After downloading, connect to your DWARF II again so the app issues the upgrade command to DWARF II.
4. After the upgrade is successful, reboot(power cycle) your DWARF II and check whether the firmware version is the latest version. You can check your firmware version in DWARFLAB App-My Device-Firmware Version.

**Before we start:
