Unable to Discover Generic Access Service (0x1800)

Hello,

 

I have an embedded device that exposes the Generic Access Service (UUID=0x1800 https://developer.bluetooth.org/gatt/services/Pages/ServiceViewer.aspx?u=org.bluetooth.service.generic_access.xml), and the device_name Characteristic (UUID=0x2A00 https://developer.bluetooth.org/gatt/characteristics/Pages/CharacteristicViewer.aspx?u=org.bluetooth.characteristic.gap.device_name.xml). 

 

When we discover all of the services (by passing ‘nil’ as the argument to `func discoverServices(_ serviceUUIDs: [CBUUID]?)`) and print them out we see all of the Services except for 0x1800.  When I use a BLE dongle on my laptop or an Android phone I am able to discover that Service and the Characteristics under it.  I have seen other apps also not show the Generic Access Service (0x1800).  Is there a way to discover this Service (and the Characteristics under it) so that we may read and write to the Characteristics?

 

Thanks,

Alex
