◆ authorizeWrite()

GattAuthCallbackReply_t authorizeWrite ( GattWriteAuthCallbackParams * params )

inherited

Invoke the write authorization callback.

This function is a helper that calls the registered write handler to determine the authorization reply for a write request.

Attention: This function is not meant to be called by user code.

Parameters

[in] params Context of the write-auth request; it contains an out-parameter used as a reply.

Returns: A GattAuthCallbackReply_t value indicating whether authorization is granted.

Definition at line 1655 of file gatt/GattCharacteristic.h.

◆ authorizeRead()

GattAuthCallbackReply_t authorizeRead ( GattReadAuthCallbackParams * params )

inherited

Invoke the read authorization callback.

This function is a helper that calls the registered read handler to determine the authorization reply for a read request.

Attention: This function is not meant to be called by user code.

Parameters

[in,out] params Context of the read-auth request; it contains an out-parameter used as a reply and the handler can fill it with outgoing data. The params->data provides a pointer to the data and params->len provides the length of this data. params->len is also used to pass the maximum size of data that the params->data can contain. If you set the params->len to a value larger than the passed in value the read operation will fail.

Returns: A GattAuthCallbackReply_t value indicating whether authorization is granted.

Note: If the read is approved, the event handler can specify an outgoing value directly with the help of the fields params->data and params->len.; If the read request is approved and params->data remains nullptr, then the current characteristic value is used in the read response payload.; The params->len parameter initially contains the maximum length of data that can be returned. Set it to the length of your data but it must not be larger than the original value.; You must also take into account the offset provided in params->offset. The params->len you provide must be larger then the offset as the read operation will attempt to read at that offset.
