SimpleBLE::Safe::Adapter::bluetooth_enabled() Calling it twice will cause a crash

[gihugui]

This function will collapse when the second adjustment is applied to the current position.

auto bluetooth_enabled = SimpleBLE::Safe::Adapter::bluetooth_enabled(); if (!bluetooth_enabled.has_value()) { outMsg = "Bluetooth enabled status err"; }

Finally, the function of windows has been solved.

Hey @gihugui, thanks for the report.

I'll leave it open so that I'll remember to go over it soon.
