Automatically reconnect to remembered devices #9

Closed klutchell closed 3 years ago

klutchell commented 3 years ago

Recent releases of balenaOS will "remember" connected devices in /var/lib/bluetooth.

https://github.com/balena-os/meta-balena/commit/3815e42f24167c0ce84a39cf0653434bacb0bd88

I've confirmed this on the following device:

ID="balena-os"
NAME="balenaOS"
VERSION="2.60.1+rev1"
VERSION_ID="2.60.1+rev1"
PRETTY_NAME="balenaOS 2.60.1+rev1"
MACHINE="raspberrypi3"
VARIANT="Development"
VARIANT_ID="dev"
META_BALENA_VERSION="2.60.1"
RESIN_BOARD_REV="a28e387"
META_RESIN_REV="9aed19a"
SLUG="raspberrypi3"

However, this bluetooth block does not reconnect to devices automatically after a power cycle. I suspect this is something that can be added via this block, but if balenaOS changes are required we can open a new issue there.

Note that this was previously fixed in balenaSound before it started using this bluetooth block.

Not sure if the same fix would apply to this block since it looks like we are now relying on the host OS for more components.

Nice, I think if paired devices are now being persisted we can use dbus to attempt the reconnect. I'll give it a shot.

Needs a tad bit more testing, but so far it works great. PR up here: #10

Hi @tmigone , thank you for your help with this issue.

How does my balenasound device (Rpi4) receive the changes? Do I need to perform an update or anything?

Thanks!
