cannot automatically reconnect after long disconnect #6

Closed andrewyates closed 5 years ago

andrewyates commented 5 years ago

Hi,

I'm encountering an issue where the app refuses to reconnect to the ZEI after it has been disconnected for a long time (overnight).

I haven't determined what threshold is required to count as a "long time." At the end of the day I place the ZEI on its stand and get the output shown below. The next morning the Linux app doesn't respond to ZEI changes until I restart it.

2018/11/21 18:50:49 ZEI disconnected 2018/11/21 18:50:49 Trying to connect to the ZEI

I'm wondering if this is some kind of Bluetooth timeout? Do you have any suggestions for what to check?

Hi,

I'm sorry to admit, but I wouldn't really know where to start. In terms of the Bluetooth connection, this tool relies on the currentlabs/ble library.

So I would recommend looking into the method "connectAndRun" in the (BluetoothManager)[https://github.com/krisbuist/timeular-zei-linux/blob/bfe4ccdcf13f325d7e8405b2201091959c7b9e67/BluetoothManager.go#L30]. Maybe the Bluetooth channel or connection doesn't get closed properly enough after a long time of inactivity.

I'm not really using this tool anymore since I'm using the native OSX application since about half a year

Thanks for looking into it. A kernel update seems to have fixed the issue, so I guess it was something specific to my hardware.
