Detailed Description
GATT Read event definition.
Instances of this type are created and passed to user registered callbacks whether the GattServer has received a read request or a GattClient has received a read response.
The GattClient only populates the fields status and error_code when it has received a read response. Callbacks attached to the GattServer do not use those fields.
