FAQ

How do I search the docs?

The top-bar search covers Chinese and English. Type and press Enter, or pick from the dropdown; Ctrl + K focuses the box. Results are ranked by relevance, and "View all results" opens the full list.

How do I switch language?

The language button in the top right toggles between 中文 and English and opens the translation of the current page. Pages without an English translation fall back to the Chinese original.

How do I report a problem?

Email [email protected] with the page link and a description. Wrong content, broken links and failing code samples are all worth reporting.

How is firmware updated?

Tap Check for updates in device settings. Firmware is served as static files from ota.lingg.cn, and the device verifies the version code before upgrading.

How does this site differ from the main site?

The main site publishes product overviews and company news; this site holds guides and technical references. For the same topic, this site is authoritative and the main site only links to it.
