SkyDemon has no choice in the matter. If you're using an external GPS it is iOS which decides what location source to give to apps.

Hopefully, iOS will make the good choice ... I will see when flying next week and keep alive this information. If it does not, it seems better to have an IPAD wifi only.

IOS makes the good choice ... it uses the internal GPS !!! I managed to connect my Galaxy phone, with bluetooth to the Garmin GLO and could compare with the IPAD, closing and opening the bluetooth connexion.  The IPAD gives the same results, with and without Bluetooth. The errors in altitude (and of course height) where between 0 and a maximum of 80 ft with the IPAD connected and not connected to the GLO. The Galaxy, when using the GLO, had errors much higher !!! almost 200 ft in some cases. The IPAD I am using now (I bought a new one) is the Mini 4, using both GPS and GLONASS, and the level of error diminished substantially compared to the previous one. The Galaxy phone has also GPS and GLONASS and the errors are smaller too, compared to the ones using the GLO !!! I do not understand why these results, as the GLO uses WAAS and EGNOSS. Anyway, the level of error of the internal devices are now acceptable. Only problem: I spent more than 100 Euros for nothing !!!!!
‌I was flying on the coastal line, close to LFMT, calibrating the Altimeter to the pressure value provided from LFMT.

I want to know if when using Garmin Glo with the IPAD, once the bluetooth connection is established, the IPAD uses automatically the information from the GLO. Apparently there is no way to know it. I will test it flying over the sea, with the barometric altimeter calibrated (my airfield is at sea level) and test if I get differences.

I can answer my question ... Using Garmin Pilot app (free for some months) I could verify that it was connected. I hope also that SkyDemon will choice the best of the two GPS sensors ... Can somebody confirm this ?
