Way to detect Bluetooth device is off on an Android? #36

Closed mobilars closed 9 years ago

mobilars commented 10 years ago

I've got a cordova-ble app on an Android (S4) device, and during startup I quite common get the following (see trace below). I think it might be because I commonly do a reset (evothings.ble.reset();) because the whole BLE-stack on Android feels unstable. It seems then that sometimes bluetooth is turned off and not back on, and I think that's the reason why I get the below trace. Is there a way to check whether BLE is on from within Javascript, and possibly turn it on?

Seems to have been fixed very well in the newest version.
