I have also updated my Ipad Mini 2 to IOS 10.1 and it now seems to read my Dual XGPS150 OK.  I had it running in the office this morning and also went for a site visit in the car and it worked fine throughout.  Hopefully this is the fix (No pun intended, honest!).

OK, took advice and updated my Garmin Glo to version 2.8, and just been for 30 minute run in the car, with NO loss of communication, so fingers crossed all is fine now. Flying tomorrow so will test it in the air and report back.

I also have connectivity problems since changing to ios10. I downloaded ios10.1 but the "waiting for location data" notification still pops up. I have rebooted everything, reset network settings, reconnected (re-paired) the Garmin Glo, but to no avail. Don't currently have much confidence in it for Tuesday's flying, so in view of likely poor viz, will also fire up my trusty Garmin 296 as back up.
Can no-one come up with a guaranteed fix?

I've updated and was going to go flying to try it out but the fog scuppered it. I tried it in the car just driving about for an hour or so and it certainly seemed stable and working so here's hoping. Knocked confidence but as always will keep the paper map to hand.

Well, just updated to iOS 10.1.......which says it has a fix for Bluetooth stability.

Hoping that works.......because there seems to be little interest from either Garmin or Sky Demon.....who both seem to have adopted a "not my fault" attitude and show no signs of seeking an improvement to the current unacceptable situation.

iOS 10.1 is now available.
I believe this was originally to be an update to add extra photo options for the iPhone 7, but amongst the long list of other improvements is "Improves bluetooth connectivity with third party apparatus"

Sounds promising........but wait for the rush to die down a bit before attempting to install.

No I haven't!  Went flying on Saturday and "Waiting for position data" came on several times.  During a particularly prolonged spell of waiting for data, I checked the Dual Status app and, whilst there was plenty of satellite data, the app was not showing any position info.  Very Strange.  I emailed Dual but so far had no response.

Think I have solved it.  Had the mode switch in the wrong setting for Ipad.  Doh!

Looks like I am having similar problems with connecting my Dual XGPS150 to my ipad mini.  the Dual monitoring app cannot see the XGPS150 either despite the bluetooth section in Settings showing that it is connected.  I have installed the latest firmware for the Dual but no difference.

I am using the following
Ipad mini2
IOS 10.0.2
SD 3.6.6.55

Think I will d/g to 9.3 this evening.

I just had a similar reply.
Hopefully, because this seems to be affecting a number of Bluetooth devices, including Bluetooth headphones, Apple will get on with the fix sooner rather than later.
Boy do I wish I hadn't bothered to update to iOS 10!
