1.2 After connecting to CoreWing APP, tuning functions cannot be used properly

After CoreWing APP connects to the powered wireless USB expansion board (hereafter referred to as 'wireless board') in BLE mode,

no device search popup appears. Among discovered devices, there is CoreWing WING-BLE.

After clicking to connect, it enters the function card page, which only shows telemetry viewing, without the tuning page or other functions.

2.2 CoreWing APP is compatible with wireless board USB expansion board firmware version 8.1.0 and above

Important

The wireless board's current factory firmware is 8.0.1. You need to use the SpeedyBee APP to upgrade the wireless board firmware to 8.1.0 in order to connect using the CoreWing APP.

Since CoreWing APP only supports version 8.1.0 and above, the 8.0.1 factory version cannot connect properly or use all functions.
