[Version 1.2] BleManagerGattCallback.nextRequest stucks after onBonded

See original GitHub issue

Hi,

I ran into the mentioned issue using version 1.2.0 of the library. The app is running on a Nexus 5 with Android 8.1. I’m trying to connect to a nRF52840 dongle, then bond. After bonding I want to change MTU size and write some characteristics on the device.

The flow in details:

after device discovery, I call BleManager.connect(BluetoothDevice)
in my BleManagerGattCallback.initGatt implementation, I push a single bond request (Request.createBond()) into the requests queue
BleManageCallbacks.onBondingRequired(BluetoothDevice) is invoked, Android pops up the Pairing notification, where I choose to pair. In the nRF Connect app, I also confirm that the pins match.
BleManagerCallbacks.onBonded(BluetoothDevice) is invoked. In my implementation I enqueue a new MTU change request here: enqueue(Request.newMtuRequest(128))

The request never gets processed since the BleManager.BleManagerGattCallback.mOperationInProgress flag is still true.

I actually checked out the source of the library and modified the BleManager implementation to reset the mOperationInProgress flag to false on successful bonding in the BroadcastReceiver’s BOND_BONDED case:

                                        Logger.i(mLogSession, "Device bonded");
					mGattCallback.mOperationInProgress = false; // added this line
					mCallbacks.onBonded(device);
					// If the device started to pair just after the connection was established the services were not discovered.
					if (mBluetoothGatt.getServices().isEmpty()) {
						mHandler.post(() -> {
							Logger.v(mLogSession, "Discovering Services...");
							Logger.d(mLogSession, "gatt.discoverServices()");
							mBluetoothGatt.discoverServices();
						});
						return;
					}
					break;

With the modifications above I managed to run the MTU change and other requests after bonding.

Is my solution valid or did I do something wrong in my intitial flow?

Thanks in advance!
