Field Documentation

ble_uuid_t* p_uuid

Pointer to the attribute UUID.

ble_gatts_attr_md_t* p_attr_md

Pointer to the attribute metadata structure.

uint16_t init_len

Initial attribute value length in bytes.

uint16_t init_offs

Initial attribute value offset in bytes. If different from zero, the first init_offs bytes of the attribute value will be left uninitialized.

uint16_t max_len

Maximum attribute value length in bytes, see Maximum attribute lengths for maximum values.

uint8_t* p_value

        Pointer to the attribute data. Please note that if the @ref BLE_GATTS_VLOC_USER value location is selected in the attribute metadata, this will have to point to a buffer

that remains valid through the lifetime of the attribute. This excludes usage of automatic variables that may go out of scope or any other temporary location. The stack may access that memory directly without the application's knowledge.
