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