Check Your Current Version: Go to Settings > About Device. Look for "MCU Version," "Build Number," and "Kernel Version." Write these down.
Identify the Brand: If you bought the unit from a major reseller (Joying, Dasaita, ATOTO), go directly to their official website. They host specific OTA (Over-The-Air) updates or downloadable files for their specific hardware.
Check the "Factory Settings": Sometimes the firmware variant is hidden in the factory settings menu (usually code 8888, 3368, or 123456).

Older firmware (pre-2023) took 15–30 seconds to reconnect to your phone. The latest update reduces this to under 5 seconds using improved BC6/BC8 stack integration.
