Remarks

This event is fired during any discovery process to indicate that the component has discovered a service, characteristic, or descriptor. Discovery processes take place whenever Discover, DiscoverServices, DiscoverCharacteristics, or DiscoverDescriptors is called.

GattType indicates what type of GATT object was discovered:

• 0 - Service
• 1 - Characteristic
• 2 - Descriptor

Uuid and Description are the UUID and Bluetooth SIG user-friendly name (if one is defined) of the discovered service, characteristic, or descriptor.

When a service is discovered:

• ServiceId is the Id of the newly discovered service.
• CharacteristicId is empty.
• DescriptorId is empty.

When a characteristic is discovered:

• ServiceId is the Id of the previously discovered service which owns the newly discovered characteristic.
• CharacteristicId is the Id of the newly discovered characteristic.
• DescriptorId is empty.

When a descriptor is discovered:

• ServiceId is the Id of the previously discovered service which owns the previously discovered characteristic.
• CharacteristicId is the Id of the previously discovered characteristic which owns the newly discovered descriptor.
• DescriptorId is the Id of the newly discovered descriptor.
