  @alejandrohcruz said in Bluetooth connections servered by the OS get the power back to SweetBlue: Are you enabling the autoConnect parameter? Also, from what I've seen, Android OS does not reconnect to bonded devices, except for A2DP ones… However, if that is happening, maybe you could disconnect/unbond when you notice that the device is stuck or when your service gets killed? Hope Hey, the autoConnect parameter is not enabled. Yes I can do disconnect/unbond the device, the problem is that the user has to open the app, because we don't get any response in the background when the Android OS controls the connection and kills our app. Currently we have a little workaround in our device that kicks the smartphone after 2 seconds in a set up state, because we found out when Android OS tries to reconnect, it get stuck in this state. So we can handle it from our device and get the control back. Edit: Is there a chance to disconnect to a device when the Android OS has the control of the connection ? Like to use the native Android LE methods ? Because if you use the SweetBlue disconnect or shutdown methods the connection is still there..

  Alejandro, If you are using a different package name for testing, then you will need a debug key linked to that package name. Email us at sweetblue@idevicesinc.com with the package name, and we'll send you a debug key.

  We are using sweetblue v2 with xamarin. I needed to basically create a java wrapper interface around the bledevice methods which required callbacks/listeners. The bindings compilation had issues with the generic type java features being used with the listeners, so I just call to my java wrapper object from c# which has simple listeners and the binding generation has no issues with. I've attached our wrapper's source code for you to use, it filters the scans without needing to call back into c# too which was a huge performance improvement.sweetbluewrapper

  What you did works, however, I would suggest using -dontwarn com.idevicesinc.**

  Yes, those trigger. We added those when we noticed that the times we set in taskTimeoutRequestFilter or DefaultTaskTimeoutRequestFilter weren't triggering.

  You can put it in a library if you want, you would just have to get a license for each app that it goes into. If you're looking to have many apps using SweetBlue, an Enterprise license may be more what you're looking for. If that's the case, email us at sweetblue@idevicesinc.com, and we can discuss your situation.

  Well, it's mostly the connecting itself which is the issue... The scanning/finding is pretty consistent now...

  @Activ84HealthEU, I need a bit more info in order to help you. Does it actually ble connect to the device? (You may have to look at logcat). When the write fails in the transaction, what is the status()? That should at least give you a hint at what's going on. NOTE: When using any transaction, you MUST call either succeed(), or fail(). Otherwise, even if the write went through, it would just stall out and do nothing afterward (and the DeviceConnectListener onEvent will never get called, at least not for being connected).

  `Well, the Sweetblue library does already make a big improvement on connection time, and the amount of phones even being able to connect... I'm mostly worried about the phones that sometimes don't connect at all, but so far, I've only seen that on a Sony in my small test team... Too bad the guy doesn't want to test again to see if my latest fixes work for that issue :S

  Unfortunately those line numbers are WAY off. If you're using proguard, please add these lines to your proguard file: -keep class com.idevicesinc.sweetblue.** { *; } -keepattributes SourceFile,LineNumberTable,Signature,*Annotation*,EnclosingMethod -dontwarn com.idevicesinc.sweetblue.**

  That shouldn't matter (where you set the config). However, if you want it to apply to all devices, I would just set the options in the BleManagerConfig when instantiating the BleManager instance. (BleManagerConfig extends BleDeviceConfig mainly for this purpose). Try doing this, and see if you get any different results.
