Lock disconnects by itself after inactivity

[francisd84]

I tried your sample code on my ESP32 and a Yale lock with a Smart module (BLE + Wifi). Wifi isn't enable.

The lock disconnects after couple of seconds after the lock/unlock command.
Using the "getLastError()" property on the BLE object of the connection returns 0, so it seems that the lock disconnects since there is no more activity.
