Member Enumeration Documentation

enum AttributeErrorCode

List of Error codes for the ATT protocol.

Enumerator:
INVALID_HANDLE 

The attribute handle given was not valid on this server.

READ_NOT_PERMITTED 

The attribute cannot be read.

WRITE_NOT_PERMITTED 

The attribute cannot be written.

INVALID_PDU 

The attribute PDU was invalid.

INSUFFICIENT_AUTHENTICATION 

The attribute requires authentication before it can be read or written.

REQUEST_NOT_SUPPORTED 

Attribute server does not support the request received from the client.

INVALID_OFFSET 

Offset specified was past the end of the attribute.

INSUFFICIENT_AUTHORIZATION 

The attribute requires authorization before it can be read or written.

PREPARE_QUEUE_FULL 

Too many prepare writes have been queued.

ATTRIBUTE_NOT_FOUND 

No attribute found within the given attribute handle range.

ATTRIBUTE_NOT_LONG 

The attribute cannot be read using the Read Blob Request.

INSUFFICIENT_ENCRYPTION_KEY_SIZE 

The Encryption Key Size used for encrypting this link is insufficient.

INVALID_ATTRIBUTE_VALUE_LENGTH 

The attribute value length is invalid for the operation.

UNLIKELY_ERROR 

The attribute request that was requested has encountered an error that was unlikely, and therefore could not be completed as requested.

INSUFFICIENT_ENCRYPTION 

The attribute requires encryption before it can be read or written.

UNSUPPORTED_GROUP_TYPE 

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

INSUFFICIENT_RESOURCES 

Insufficient Resources to complete the request.

WRITE_REQUEST_REJECTED 

The Write Request Rejected error code is used when a requested write operation cannot be fulfilled for reasons other than permissions.

CLIENT_CHARACTERISTIC_CONFIGURATION_DESCRIPTOR_IMPROPERLY_CONFIGURED 

The Client Characteristic Configuration Descriptor Improperly Configured error code is used when a Client Characteristic Configuration descriptor is not configured according to the requirements of the profile or service.

PROCEDURE_ALREADY_IN_PROGRESS 

The Procedure Already in Progress error code is used when a profile or service request cannot be serviced because an operation that has been previously triggered is still in progress.

OUT_OF_RANGE 

The Out of Range error code is used when an attribute value is out of range as defined by a profile or service specification.

uint8_t  error_code_ 
)

Construct an attribute error response in the case where there was no attribute handle in the original response or if the request is not supported.

Parameters:
request_opcode_The Attribute opcode of the request that generated the error.
error_codeThe reason why the request has generated an error.

Field Documentation

const uint8_t error_code

The reason why the request has generated an error response.

Definition at line 169 of file AttServerMessage.h.
