I purchased a used Oxygo Next (identical to Inogen G5) O2 concentrator for my experimental aircraft. This is a common use for this unit. To connect to the bluetooth app I need a "Provider Number" but don't have one. I'm working with the manufacturer but have not gotten a number from them yet. Can someone enlighten us on at least the format of such a number if not an example of an actual Provider Number? Thanks
Equipment: Oxygo Next
