There's some strangeness with the BT anyway - Rockpool doesn't work at all if BT is disabled on boot then enabled, because the adapter isn't present at all and it only watches for state changes. If it's switched off after boot then it stays around but its state is disabled, which is what Rockpool's expecting.

I think the BT implementation in Sailfish is going to change quite a bit soon, and we'll possibly have completely different bugs after that. So I thought the 'restart service' would be a good temporary fix.
