Cannot cancel connection with using autoConnect

[VincentMasselis]

I was connecting with autoConnect (but not yet connected) and, at some point, I decide to cancel the pending connection, the disconnection request is correctly enqueued but nothing appends, internalDisconnect is never called.

I'm using the last commit on develop (the one this morning), the cause of the bug seems to be the bool operationInProgress set to true here ->
https://github.com/NordicSemiconductor/Android-BLE-Library/blob/develop/ble/src/main/java/no/nordicsemi/android/ble/BleManagerHandler.java#L2828 causing the disconnection request to be enqueued and but never launched.

Yes... this use case may not be supported.

[VincentMasselis]

😢 Do you have any workaround that I could use for the moment ?

[philips77]

The initial connection, even with autoConnect = true is done with this param set to false (although see #250). It should timeout in 30 seconds, or when you set .timeout(...) parameter to the ConnectRequest. You may try calling close() and connect(...).enqueue() again, but I can't guarantee it will work as expected.

[VincentMasselis]

By close() you mean the one from BleManager or BleManagerHandler ?

If you're talking about BleManagerHandler, it's not going to work since this comment :
https://github.com/NordicSemiconductor/Android-BLE-Library/blob/develop/ble/src/main/java/no/nordicsemi/android/ble/BleManagerHandler.java#L431

[philips77]

True... How about using a different BleManager instance then?

[VincentMasselis]

Firstly, i'm injecting my manager instance at some places in my code, it's not gonna be easy to swap from one instance to another because of this IOC.
Secondly, forgetting my previous BleManager instance doesn't stops the running autoConnect that I want to cancel, which leads, i think, to memory leaks.

[philips77]

You're right. Cancellation would really be a nice to have feature. I can look at it next week, but it's my last week before 3-month leave, so I can't promise much.

[VincentMasselis]

I'm sending all the virtual encouragements I could behind my computer 💪

[philips77]

I've started working on this feature now.
