@ryanbis Thank you for your information. I'm glad to hear the progress. From your comment, it seems difficult to release in this year. Is it likely to be released early next year?

I must admit, I'm not as familiar with that method of pairing. Usually you just call the bond method, and then a dialog will pop up requesting the pin. However, I would suggest that since you seem to have control over the firmware of the product, to implement your own encryption scheme. Android's pairing process can work well on some phones, but on others it can be a nightmare. I'd look into using a couple of characteristics for transmitting and receiving encrypted data. You can set up some kind of key exchange between the 2 to establish a session secret to use for encrypting/decrypting data. Easiest way would be to just implement pairing the standard way, and just call bond() to do so (but you will run into bonding issues on some phones).

Yes, as long as you request those permissions at runtime as well as adding them to the manifest.

@ryanbis Would you please tell me how is the progress of support Android 12? I think it will come soon...

If you're not setting a custom BondFilter, then something else is going on. The connection bug fix should only happen if you set a custom BondFilter, the DefaultBondFilter doesn't run the connection bug fix. @teruyama said in ConnectionBugHack: The customBondFilter is not set. I have set autoBondFixes to false. Since the target device uses passkey authentication, I don't want it to unbond every time it is disconnected. I am using the following code to bond, connect and it happens every time on Google Pixel3 and other smartphones. I assume you are referring to the bondFilter field in BleDeviceConfig/BleManageConfig as there is no customBondFilter field. Are you seeing device get unbonded when you disconnect? This shouldn't happen in normal circumstances. As far as not re-bonding, I wish you well. There are some devices (many Sony, and Motorola devices) that don't handle bond credentials very well. I'm hoping for you sake that they handle it better when a pin code is required. Have you changed any settings in BleDeviceConfig/BleManagerConfig? If so, please post what they are.

If you're just talking about BLE notifications, then yes you can get notifications in the background. Not sure what you're referring to with notification services. If you're talking about android notifications, that's not handled by SweetBlue, you would have to implement those in the callback for the BLE notifications.

It's something that is on our radar, however we have no timetable for when that will happen. Just wanted to post here to let you know we are aware of it.

@hayashi Due to the way Azure Artifacts works, we were forced to create a new feed. See https://forum.sweetblue.io/topic/152/new-maven-server for the new URL (basically, just tack a 3 onto the second sweetblue in the url).

@ryanbis the fix to this connection loop went out with 3.2.3 right? I had implemented the methods in DefaultReconnectionFilter , to workaround the issue described here https://forum.sweetblue.io/topic/12/explicit-disconnect-triggers-automatic-reconnect/15 Now the workaround fails. How do we simply tell Sweetblue -- hey, disconnect now and do not retry to connect until we call connect() again?

Thanks a lot for the fixes and documentation! @ryanbis

@ryanbis Ah! Alright, everything's clear now. That was the confusion

@blawlor Funny enough, I'm seeing this behavior despite using a foreground service to scan. So in theory I shouldn't need the background location permission. Have you seen something like that too?

@ryanbis Perfect! Thanks a lot. This is great.

@alejandrohcruz Set autoBondFixes to false.

You're right, thanks for pointing that out. It's been fixed now.

Issue solved... make sure to add Java 8 compatibility to project. compileOptions { sourceCompatibility JavaVersion.VERSION_1_8 targetCompatibility JavaVersion.VERSION_1_8 }

Thanks for getting back with me. It appears I get the same results using the Toolbox app, but did notice something interesting. My flow using Toolbox app after having connected to two devices Turn device 1 on. Wait for button to turn green and say "Disconnect". Usually takes about 5-10 seconds I'm able to get notify values Turn device off. Wait for button to turn white and say "Connect" ========= Turn device 2 on. Wait for button to turn green and say "Disconnect". Usually takes about 5-10 seconds. I'm able to get notify values Turn device off. Wait for button to turn white and say "Connect" This is pretty consistent. I can do this multiple times with the same result, but sometimes when I turn a device on, it's button will not turn green even after waiting for over a minute. But as soon as I turn on another device (two devices are now on), both devices will connect and buttons will turn green. When a third device is added, the only way I can get a device to connect and turn green, is to turn on another device too. This is pretty consistent with results I'm seeing with Sweetblue in our app. We try to connect to devices use a ReconnectFilter val deviceReconnectFilter = object : DeviceReconnectFilter { override fun onConnectFailed(connectFailEvent: DeviceReconnectFilter.ConnectFailEvent): ConnectFailPlease { return ConnectFailPlease.retry() } override fun onConnectionLost(connectionLostEvent: ConnectionLostEvent): ConnectionLostPlease { return ConnectionLostPlease.retryIn(Interval.secs(3.0) ) } } So our app is continuously trying to connect to devices it knows about. When device is turned on ConnectionEvent is triggered and we start getting data. When the device is turned off, onConnectionLost is fired and we start continuously trying to reconnect. Is there another way we should be trying to handle continuously being connected to a device?
