POD SLOT x4
	bool isBound;
	bool isSticky;
	string deviceID;
	BLEDevice dev;

CANDIDATE DEVICES (list of BLEDevice)
	STATE:
		- ATMATCHING -> Association Token matching
		- CONNECTING -> Connection in progress
		- DISCCHARS -> Discovering characteristics
		- SUBSCRIBING -> Subscribing to characteristic
		- HANDSHAKE -> Exchanging initial messages
		- READY -> Assign to slot and remove from candidate list

Operations
==========
Startup()
Shutdown()
ScanForDFUDevices()
StopScanningForDFUDevices()

(per slot)
	setSticky(sticky) -> When the connection is lost, it scans and tries to reconnect

	freeUp()
		-> Frees up the slot. If a Pod is connected, then it will be disconnected.

	findAndConnect(keepml)
		-> Displays ML, and tries to connect to the device over it
		-> Can't be done if the slot is bound to a device. Need to call freeUp first

	abortFinding()
		-> Stops device scan and ML

	disconnect()
		-> Closes connection to device and fires 'Disconnected' event

	reconnect()
		-> Tries to reconnect to last device w/o ML

	(proxy functions)
		sendCommand(cmd)
		uploadFile(stream, id, unique, cmdcb, filecb)
		downloadFile(stream, id, unique, cmdcb, filecb)

	getID()
		-> Gets UID / BDADDR of the device (to track different devices)

	setMLState(enabled)

	Events
	======	
	(Connection events)
		-> UpdateRequired(pod/app) -> The Pod in this slot cannot be connected until a firmware or app update is done
		-> Connected
		-> Disconnected (unexpected/requested/dfu)
		-> Timeout -> Operation timeout. Connection is closed.

	(ML of each slot)
		-> status change (white/black) per frame
