Did anyone successfully pair your sfos(x) with Polar sportwatch? I still cannot make it work. Polar says pairing failed and a for says pairing complete.
There are device specific problems with BTLE.
From the asteroid front, i know piggz has some working bits to connect asteroid watches and fitbip bands via btle but on Jolla C (and sfosx?) it is not working reliably or not at all. Jolla is informed but not moving fast afaik.
