How to turn off auto connect

[StevenParticipant]

Hey all!

My use case involves having several FloBLE Pluses at an event space, each connected to one iPad. I would like to build an app that shows the FloBLE devices available to connect to, and when a user selects one in the table, the iPad will connect only with that device. Later, I would like to have a button that disconnects the iPad from it’s currently connected device and frees it up for other iPads to connect to it.

In order to execute on this plan, I need to be able to turn off the auto connect that happens when initializing the FmSessionManager. I would also need to know how to connect to a device with its UUID and also disconnect from said device. Is this possible with the Flomio SDK Pro?

Thanks!

After playing more with the FmSessionManager singleton, I have found the stopReader() method. This definitely works for disconnecting from the reader. However, because the FmSessionManager auto connects to the first available reader, it will automatically find this reader and reconnect to it. 😛

Hi Steven,

There is a feature specificDeviceUuid on FmConfiguration that you should use, with this you can connect to a FloBLE Plus using the device uuid for example RR123-456789. You can use your own core bluetooth instance to see advertised UUIDs, then initialize the SDK with that.

You would use this delegate method and use the name parameter on the peripheral object: Apple docs

A less elegant solution is to use the sticker at the back of the device and manually type it in.

Let me know if you have any more questions about this.

Great idea, Scott! Why didn’t I think of that? I’ll let you know if I have any trouble with it.

Unfortunately it doesn’t look like this is a solution. Here’s an example of what gets returned when centralManager(_ central: CBCentralManager, didDiscover peripheral: CBPeripheral, advertisementData: [String : Any], rssi RSSI: NSNumber) returns:

<CBPeripheral: 0x1c03005a0, identifier = 6D7FB6BA-5332-180B-8FC7-F9F93692E107, name = ACR1255U-J1-004839, state = disconnected>
	-advertisementData: ["kCBAdvDataIsConnectable": 1, "kCBAdvDataServiceUUIDs": <__NSArrayM 0x1c0249ea0>(
FFF0
)
, "kCBAdvDataLocalName": ACR1255U-J1-004839]
	-RSSI: -46

As you can see the name property is “ACR1255U-J1-004839” and not the ID that FmConfiguration will take. So right now, I’m just going to advertise what device the app is currently connected to or display “Scanning…” if it’s not connected to anything. Not perfect, but it’ll work as long as we control our power-on sequence.

Sorry your most recent post wasn’t responded to.
You should be able to use the last 6 characters of the above ACR1255U-J1-004839 to connect to devices using specificDeviceId.

Let me know if you have any issues,
Scott
