Hello @caeduk, nice to see you here Just wanted to mention that there's rxjava3-bridge that can convert between rx2 and rx3 and that has helped me many times when migrating apps to rx3. https://github.com/akarnokd/RxJavaBridge

Hello, we have similiar issue (also tested with setting autoBond to false/true has no affect). We noticed that the Sony Xperia 1 is connected to our BLE device and 60 seconds later it got unbound / unpaired from the smartphone. We tested it with different scenarios to exclude sources of issue (as it is a coffee machine we turned it off before the 60 seconds where over to verify that the coffee machine didnt caused this). My question is: can this be a issue by Sweetblue or is it more a Sony only issue ? (as it only happens on this devices).

@ryanbis Thank you for reply and advice. I answer to your questions one by one. Are all of the tests above taken from the same device/tablet? Sorry for my insufficient information. I've updated the table of Summary of our faced issue. I use HUAWEI MediaPad T5 with Android 8.0.0 and Lenovo YT-X705F with Android 10. Can you also list all the BleManagerConfig options you have set? I dumped all member of BleManagerConfig instance which we hand over to BleManager.get(). We changed loggingOptions as needed and updateThreadType only. 12-20 14:59:59.391 10905 10905 E BLE_CORE: loggingOptions : com.idevicesinc.sweetblue.LogOptions@4c8969b 12-20 14:59:59.391 10905 10905 E BLE_CORE: timeTrackerSetting : Off 12-20 14:59:59.391 10905 10905 E BLE_CORE: logger : com.idevicesinc.sweetblue.defaults.DefaultLogger@e2d8a38 12-20 14:59:59.391 10905 10905 E BLE_CORE: defaultManagerStates : [Lcom.idevicesinc.sweetblue.BleManagerState;@8d11a11 12-20 14:59:59.391 10905 10905 E BLE_CORE: enableCrashResolver : false 12-20 14:59:59.391 10905 10905 E BLE_CORE: enableCrashResolverForReset : true 12-20 14:59:59.391 10905 10905 E BLE_CORE: stopScanOnPause : true 12-20 14:59:59.397 10905 10905 E BLE_CORE: scanClassicBoostLength : -1secs/-1000millis 12-20 14:59:59.398 10905 10905 E BLE_CORE: infiniteScanInterval : 10secs/10000millis 12-20 14:59:59.398 10905 10905 E BLE_CORE: infinitePauseInterval : 0.5secs/500millis 12-20 14:59:59.398 10905 10905 E BLE_CORE: autoScanDuringOta : false 12-20 14:59:59.398 10905 10905 E BLE_CORE: revertToClassicDiscoveryIfNeeded : true 12-20 14:59:59.398 10905 10905 E BLE_CORE: updateThreadType : HANDLER_THREAD 12-20 14:59:59.398 10905 10905 E BLE_CORE: updateHandler : null 12-20 14:59:59.399 10905 10905 E BLE_CORE: postCallbacksToMainThread : true 12-20 14:59:59.399 10905 10905 E BLE_CORE: manageCpuWakeLock : true 12-20 14:59:59.399 10905 10905 E BLE_CORE: requestBackgroundOperation : false 12-20 14:59:59.399 10905 10905 E BLE_CORE: autoPauseResumeDetection : true 12-20 14:59:59.401 10905 10905 E BLE_CORE: uhOhCallbackThrottle : 30secs/30000millis 12-20 14:59:59.401 10905 10905 E BLE_CORE: manageLastUhOhOnDisk : true 12-20 14:59:59.401 10905 10905 E BLE_CORE: blockingShutdown : false 12-20 14:59:59.402 10905 10905 E BLE_CORE: autoScanDelayAfterResume : 0.5secs/500millis 12-20 14:59:59.402 10905 10905 E BLE_CORE: autoScanDelayAfterBleTurnsOn : -1secs/-1000millis 12-20 14:59:59.402 10905 10905 E BLE_CORE: autoScanPauseTimeWhileAppIsBackgrounded : -1secs/-1000millis 12-20 14:59:59.403 10905 10905 E BLE_CORE: idealMinScanTime : 5secs/5000millis 12-20 14:59:59.403 10905 10905 E BLE_CORE: autoUpdateRate : 0.02secs/20millis 12-20 14:59:59.404 10905 10905 E BLE_CORE: defaultStatePollRate : 0.1secs/100millis 12-20 14:59:59.404 10905 10905 E BLE_CORE: idleUpdateRate : 0.5secs/500millis 12-20 14:59:59.404 10905 10905 E BLE_CORE: minTimeToIdle : 20secs/20000millis 12-20 14:59:59.405 10905 10905 E BLE_CORE: delayBetweenTasks : -1secs/-1000millis 12-20 14:59:59.405 10905 10905 E BLE_CORE: scanReportDelay : 0secs/0millis 12-20 14:59:59.405 10905 10905 E BLE_CORE: defaultScanFilter : null 12-20 14:59:59.405 10905 10905 E BLE_CORE: defaultNativeScanFilterList : [BluetoothLeScanFilter [m_deviceName=null, m_deviceAddress=null, mUuid=null, m_uuidMask=null, m_serviceDataUuid=null, m_serviceData=null, m_serviceDataMask=null, m_manufacturerId=-1, m_manufacturerData=null, m_manufacturerDataMask=null]] 12-20 14:59:59.405 10905 10905 E BLE_CORE: defaultDiscoveryListener : null 12-20 14:59:59.405 10905 10905 E BLE_CORE: scanApi : AUTO 12-20 14:59:59.406 10905 10905 E BLE_CORE: scanPower : AUTO 12-20 14:59:59.406 10905 10905 E BLE_CORE: updateLoopCallback : null 12-20 14:59:59.406 10905 10905 E BLE_CORE: serverFactory : com.idevicesinc.sweetblue.internal.android.IBluetoothServer$DefaultFactory@29c464d 12-20 14:59:59.406 10905 10905 E BLE_CORE: bluetoothManagerImplementation : com.idevicesinc.sweetblue.internal.android.AndroidBluetoothManager@6839502 12-20 14:59:59.406 10905 10905 E BLE_CORE: uuidNameMaps : null 12-20 14:59:59.406 10905 10905 E BLE_CORE: defaultListComparator : com.idevicesinc.sweetblue.BleManagerConfig$DeviceNameComparator@ef93e13

@ryanbis I'm very glad 3.2.7 is released! Thank you for your prompt service. We are now verifying notify/write on single characteristic with setting UpdateThreadType as HANDLER_THREAD.

Debug keys do not work forever like a production lifetime license. Just email us at sweetblue@idevicesinc.com and let us know the package name, and we can re-generate a new one for you.

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.

@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?
