hi all: how to use sd_ble_gattc_relationships_discover to discover att handle?

as my question Use Nordic BTLE Soc with other Vendor BTLE Compatibility

i found this issue that nordic sdk(s120 and mastercontrol panel) use Primary Service Discovery and softdevice(contain a Primary Service 0x2800).

so when i use Vendor BLE module ,that will not return group type response from slave. when i use iphone with vendor ble module, that use read by type with UUID(Device Name) as attachment file(*1 and *2).

Are you looking for details on how to use the sd_ble_gattc_relationships_discover() or are you having other issues?

What chip and SDK are you using? Can you be more specific on how you setup your tests and what it is that actually doesn't work the way you thought it would?
