Raspberry Pi 3 not connecting to Control+ Hub #191
Description
Hi, first point: Thank you to all the participants in this project for doing a great job.
I was using this library to connect my Raspberry Pi 3 to the Control+ Lego Hub without any issues. However, after a Raspberry update (I assume), it suddenly stopped working; the Raspberry Pi is no longer able to connect to the hub via Bluetooth.
Some points:
I did not change my code, so I assume it is an issue related to the Raspberry Pi and the Bluetooth connection—perhaps something related to the noble Bluetooth library?
My MacBook Pro can connect to the hub without any issues.
I checked for any pending firmware updates for the Lego Control+ Hub using the Lego App, and it appears to be up to date.
- I've tried using bluetoothctl, and I can see
[NEW] Device 90:84:2B:7A:F8:D6 Technic Hub
When trying to pair, I get:
[bluetooth]# pair 90:84:2B:7A:F8:D6 Attempting to pair with 90:84:2B:7A:F8:D6 [CHG] Device 90:84:2B:7A:F8:D6 Connected: yes Failed to pair: org.bluez.Error.AuthenticationFailed
- I read this issue: Does not connect to the hub? #26
