Hi Mikel, Thanks for all the help so far! I've gotten a bit further again, but no sigar yet! Enable=Gateway was definitely the ticket: I set it and now HandsfreeGateway.Connect shows up and executes correctly, my phone suddenly shows a new checkbox "Phone audio: Connected to phone audio". Superb! So I called myself as a test and -lo and behold- the bluetooth symbol shows up when I pick up. However, after this I checked the PA sources and no bluetooth source is to be seen. Not only that, when I hung up the phone my kernel bailed out on me :-) (I suppose this now takes me to ofono configuration land?) - bram On Fri, Jun 14, 2013 at 12:03 PM, Mikel Astiz <mikel.astiz.oss at gmail.com> wrote: > Hi Bram, > > On Fri, Jun 14, 2013 at 10:20 AM, Bram de Jong <bram.dejong at gmail.com> wrote: >> Hi Mikel, >> >>> As Tanu mentioned, this can be done calling >>> HandsfreeGateway.Connect().
