Restricted service

[Slion]

The other day it was working just fine but today I just can't get the connection to work. I keep getting the following error: Restricted service: Status=AccessDenied Can't read characteristics. Press Control+Shift+F5 before starting program again.

No matter how many time I restart the app it's the same issue.

I tried a lot of stuff to get it working but nothing worked. No amount of pairing and reboot seems to get it to work again.

try commenting this line out and see, that issue used to happen quite often when I first started working on this project. It barely happens now but still pops up once in a while.

It was happening from time to time before for me too but usually a restart would fix it.

I could connect the controller to a Samsung S7 Edge with the Oculus app, it did check for firmware update and I could go through the calibration.

Sometimes it connects briefly but then drops, it also looks like it was lagging, very slow response to mouse move. I could get the trackpad to work somehow by leaving the controller on the table and just touching the trackpad. As soon as I pick the controller the connection drops somehow.

Similar issues with: https://github.com/ilyabru/GearVrController4Windows I could connect like once and I was getting values but it lags and when I pick it up it disconnects.

I'm going to leave the batteries out for the night, see if that helps but I doubt it. I wonder if there is a way to reset the controller.

Changed the batteries even though they were showing 59%. Some issues, showing 76% charge.

The issue maybe due to not disconnecting properly. when I was testing out your pull request, it wouldn't auto connect when I close the app and reopen it. By telling it to disconnect on close did resolve that issue. 0ef05797f62f5e377362f7105a61095950e30e1c

This morning after rebooting the PC again I could pair again and now it works. I did switch back to master pull your changes but I have not closed the application yet so that can't be it. Though I'm sure they help and make sense. I blame Windows for being so unreliable with Bluetooth.

Which Bluetooth hardware are you using? I'm using Asus BT-400.

[minhe7735]

Techkey USB Mini Bluetooth 5.0 EDR. Not sure if Bluetooth 5 with EDR makes a difference.

Not sure if Bluetooth 5 with EDR makes a difference.

Seems to be working well enough when it wants to with Bluetooth 4.0 on that Asus BT-400. Closing this issue as the fix was to try again in the morning 😁 Thanks for the hardware tip I'll be trying it.

I've switched from that Asus BT-400 to a UGREEN Bluetooth 5.0 USB Adapter and it seems that dongle performs much better with any device apparently. Device scan is pretty much instantaneous compare to the sluggish BT-400. Connection to the GearVR Controller is also much faster.
