BLE Disconnection after some time #477

Open jayjoshi1995 opened 2 years ago

jayjoshi1995 commented 2 years ago

I'm doing some tests with bleno installed on a Raspberry Pi, and i'm experiencing big issues with secure characteristics.

I can replicate this scenario with LightBlue on android and iPhone.

If i define a service with a secure charachteristic, when i try to read this charachteristic, bleno fires the disconnect callback, and it freezes until i restart it.

I've already upgraded to bluez 5.64, nothing changed.
