unreliable auto connection ...

[Jonathan Lin]

We've been suffering Unreliable Auto Connection for quite a while... "autoConnect" sometimes just doesn't work to get the device back to connection. Below is the failure message returned whenever the problem happened.

Any of you have ideas? Many thanks in advance!

Appear the message "L2CAP got BLE scanner conn_comp in bad state: 4" The device can't re-connect. Using gatt.connectGatt to connect with auto=true ...

This happened on Android devices, and the message received was from Android OS middleware. We simple use "auto connect" command, and sometimes it fails with this error.

@JonathanLin: Could you try to test with nRFConnect ?, you can enable AutoConnect in the drop down arrow when you connect. Which phone did you try? Which Android version?
