BLE Reconnection Fails After GoPro Battery Removal or Extended Idle Time (Requires Manual Re-pairing)

[areiner222]

Component
What is the bug in?

• Demos (python sdk, etc) - Using WirelessGoPro / python sdk

Describe the bug
I can successfully pair my gopro via ble and then connect with the WirelessGoPro (connecting and disconnecting successfully). However, if the battery is removed / changes or the camera sits idle for long enough after powering off then I cannot reconnect via ble without manually repairing.

Repro

gp0 = WirelessGoPro(
    target=target0,
    enable_wifi=False,
    maintain_state=False,
)
await gp0.open()
