advertising iphone using NRF connect 2.21 for IOS. (very basic). instuctions?

[rexx]

Sorry this is very basic. Not really for NRF connect for Desktop. But for NRF connect for IOS.

1.I'm just trying to  have my iPhone (iphone 6 ,  IOS 12.4.6) use NRF connect (for Ios version 2.21)  to advertise the Iphone itself.  I couldn't find any instructions,  [At this point I'm not even trying to create an actual connection]

2. Sometimes it works  - meaning iphone is seen as peripheral by a ble scan running on another device (android). The android is fine picking up all sorts of things on its scan.   But sometimes it doesn't find the iphone right next to it.

3. through trial and error I seem to have created an Advertiser Profile that works sometimes - though NRF connect kept giving be a "bad format" response when I tried to tap on the profile created.

4 I run the scanner (sometimes I get a 'problem with your blootooth error' but that goes away when I hit scan.  And then turn on the advertiser.i also changed Setting/Scanner/ Automatic Read after Write to YES.

Anyway - is there any basic documentation on this? Thanks very much,

thanks

1. maybe it's the old phone - I'll borrow another phone and try that.

2. but there isn't any documentation on this IOS App which I was just trying standalone -  is that all in the windows version of NRF Connect?

3. i was just trying to use the default advertising, just to test. 

4. the advertiser state says "yes" (see attached screen shots)

5 the app wouldn't really let me do too much to tweak the advertiser.

I choose advertiser.  Then new advertiser. then add service. App gives error "import error - the data couldn't be written  because it isn't in the correct format". But it also creates a "generic Access service" at the same time it gives me that error.
