(very) Frequent "Bluetooth is disabled" when scanning, both iOS and Android

[dariosalvi78]

I am using the startScan() function to trigger a request of permissions (I wish there was an explicit function for that TBH). This is done daily, to access a device.

We have observed that very frequently, the startScan() function would fail with a "Bluetooth is disabled" message. Repeating the operation would usually make it disappear (the startScan goes), but often it has to be repeated even more than once. This is annoying from the user perspective as they get an error message.

Any idea why this is happening?
Any suggestion about how to solve it?

Hi!

This sounds related to #828, except that only applies to iOS. The best workaround (and it is only a workaround) is here:

#768 (comment)

What are the log messages you are seeing attached to this on Android?

I agree that some more explicit permissions request methods would be great... patches towards this are definitely welcome. There's been some discussion on #944 about this topic, but no-one has put forward any patches or concrete designs at this point.
