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.

Attention: 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.

ble::connection_handle_t connHandle

Handle of the connection that triggered the event.

Definition at line 158 of file gatt/GattCallbackParamTypes.h.

const uint8_t* data

Pointer to the data read.

Attention: Data may not persist beyond the callback scope.
