Managed it to make it work. What you need is the application id, not the package name. Very confusing.

To be honest, it's been a while since I've dug deep into the numbers for connection interval. I would think 100ms would be good, just make sure to test like crazy :).

@caeduk interesting, I didn't know that you can do that if you scan without filters. We can probably look into their source code and find more hints i.e. see under which conditions they trigger that notification to ask the user if they want to debug the connection

There is nothing in sample apps. Any possibility of it in being released in future ?.

Thank you for your replies. It is interesting that you got different results than me. On my undersanding, turning off the Bluetooth adapter definitely terminates the connection and thus the device can be used again for further scanning/connection. I've been trying out a bunch of different things. Sometimes, when the device is stuck on this state, I am able to retrieve the device from the regular getDevice(String macAddress) method. And then I can establish a connection, verify the BONDED state, read the standard Device Information Service, and even enable some BleNotify. However, I am not able to negotiate the MTU as the operation fails with a REMOTE_GATT_FAILURE due to “no resources”. I'll activate autoNegotiateMtuOnReconnect and try again tomorrow, maybe you have some magic in there or I'm doing something wrong. Other than that, I think I'll use the getDevices_bonded() function, filter for the device, and unbond it. Then connect again. That seems to work on the Toolbox V3 app and does not retrigger a bonding notification for some reason.

Undiscover will disconnect, but will not explicitly unbond.

@caeduk Please post a new topic with specific steps to reproduce the issue you're having so we can investigate it on our end.

I found your post here https://forum.sweetblue.io/topic/12/explicit-disconnect-triggers-automatic-reconnect and I was actually able to make it work, but it's tricky

@benp thanks a lot, will check it out!

@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..

Hi, any updates or plans on this? It would still be very meaningful. Thanks!

Hi, any updates on the Android Q testing? The APIs are now final on the Android SDK. Thanks!

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.**
