Description
I'm trying to search for and connect to a BLE device (from a Pi) in a loop w/ a connect timeout, and it always eventually hangs with the below goroutine trace.
The connect is being called with a timeout context:
ctx := ble.WithSigHandler(context.WithTimeout(context.Background(), time.Second*5))
cln, err := ble.Connect(ctx, pm5.filterAdvert)
goroutine 27 [chan receive, 26 minutes]:
