◆ BT_ATT_ERR_AUTHENTICATION

#define BT_ATT_ERR_AUTHENTICATION   0x05

#include <include/zephyr/bluetooth/att.h>

◆ BT_ATT_ERR_INSUFFICIENT_ENCRYPTION

#define BT_ATT_ERR_INSUFFICIENT_ENCRYPTION   0x0f

#include <include/zephyr/bluetooth/att.h>

The attribute requires encryption before it can be read or written

◆ BT_ATT_ERR_INSUFFICIENT_RESOURCES

#define BT_ATT_ERR_INSUFFICIENT_RESOURCES   0x11

#include <include/zephyr/bluetooth/att.h>

Insufficient Resources to complete the request

◆ BT_ATT_ERR_INVALID_ATTRIBUTE_LEN

#define BT_ATT_ERR_INVALID_ATTRIBUTE_LEN   0x0d

#include <include/zephyr/bluetooth/att.h>

The attribute value length is invalid for the operation

◆ BT_ATT_ERR_INVALID_HANDLE

#define BT_ATT_ERR_INVALID_HANDLE   0x01

#include <include/zephyr/bluetooth/att.h>

The attribute handle given was not valid on the server

◆ BT_ATT_ERR_INVALID_OFFSET

#define BT_ATT_ERR_INVALID_OFFSET   0x07

#include <include/zephyr/bluetooth/att.h>

Offset specified was past the end of the attribute

◆ BT_ATT_ERR_INVALID_PDU

#define BT_ATT_ERR_INVALID_PDU   0x04

#include <include/zephyr/bluetooth/att.h>

The attribute PDU was invalid

◆ BT_ATT_ERR_NOT_SUPPORTED

#define BT_ATT_ERR_NOT_SUPPORTED   0x06

#include <include/zephyr/bluetooth/att.h>

The ATT Server does not support the request received from the client

◆ BT_ATT_ERR_OUT_OF_RANGE

#define BT_ATT_ERR_OUT_OF_RANGE   0xff

#include <include/zephyr/bluetooth/att.h>

Out of Range

◆ BT_ATT_ERR_PREPARE_QUEUE_FULL

#define BT_ATT_ERR_PREPARE_QUEUE_FULL   0x09

#include <include/zephyr/bluetooth/att.h>

Too many prepare writes have been queued

◆ BT_ATT_ERR_PROCEDURE_IN_PROGRESS

#define BT_ATT_ERR_PROCEDURE_IN_PROGRESS   0xfe

#include <include/zephyr/bluetooth/att.h>

Procedure Already in Progress

◆ BT_ATT_ERR_READ_NOT_PERMITTED

#define BT_ATT_ERR_READ_NOT_PERMITTED   0x02

#include <include/zephyr/bluetooth/att.h>

The attribute cannot be read

◆ BT_ATT_ERR_SUCCESS

#define BT_ATT_ERR_SUCCESS   0x00

#include <include/zephyr/bluetooth/att.h>

The ATT operation was successful

◆ BT_ATT_ERR_UNLIKELY

#define BT_ATT_ERR_UNLIKELY   0x0e

#include <include/zephyr/bluetooth/att.h>

The attribute request that was requested has encountered an error that was unlikely.

The attribute request could therefore not be completed as requested

◆ BT_ATT_ERR_UNSUPPORTED_GROUP_TYPE

#define BT_ATT_ERR_UNSUPPORTED_GROUP_TYPE   0x10

#include <include/zephyr/bluetooth/att.h>

The attribute type is not a supported grouping attribute.

The attribute type is not a supported grouping attribute as defined by a higher layer specification.
