Yes. Like it was mentioned in the post i referred to, on iOS you will only see devices that is natively supported by iOS, e.g. HID, HRM, ANCS etc. So you have to have one the UUID of one of these services in the advertisement packet for it to be shown without an app.

Thank you for response!

Today I've been playing around this issue and found out that I had to exhibit UUID of HID service (0x1812) in advertise packet to make device recognizable even though it actually not exist. I also tried to include another UUIDs instead, such as GAP service (0x1800) or any custom 128-bit UUID, but it doesn't work. Seems like iOS filters devices by supported services. It's bit confusing, because in Apple Bluetooth Accessory guidelines not specified what services should be exposed. Moreover, TX Power Level that considered mandatory for advertising data is not required in fact.

I think that workaround for this issue could be in including ANCS UUID to advertise packet, but I don't think it's correct solution.

Hi,

Have a look at this post. You probably haven't included the supported services.
