I had reached the point of frustration with lost connections between PAW and SD (previously reported/discussed on these forums but not solved) that I had given up using PAW. However as of today I have the latest version of SD and the latest software on PAW. This now allows me to select PAW in SD as my GPS source (previously I had to use FLARM). I have been testing the connection at home on two Android tablets and provide a link to a video of the result (see below and notice the "waiting for device" message on the larger tablet at the 5 second mark)). The cheap 7" tablet has no problems, but the more expensive 8" has random and intermittent messages "waiting for device".
However the big change and huge improvement is that SD does not drop out of "flying mode" and just waits until the message clears and then carries on.
I have tried various PAW wifi settings without noticeable difference. So although there is a huge improvement in useability of PAW with SD I am at a loss as to why the cheap tablet ploughs along happily, whilst the expensive (Lenovo Tab3 8" Android 6) one keeps stopping with the "waiting for device" message.
Any help much appreciated as it would be nice to get this resolved for everyone affected.
