Field Documentation

uint16_t ble_gatts_attr_t::init_len

Initial attribute value length in bytes.

Definition at line 229 of file ble_gatts.h.

uint16_t ble_gatts_attr_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.

Definition at line 230 of file ble_gatts.h.

uint16_t ble_gatts_attr_t::max_len

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

Definition at line 231 of file ble_gatts.h.

ble_gatts_attr_md_t const* ble_gatts_attr_t::p_attr_md

Pointer to the attribute metadata structure.

Definition at line 228 of file ble_gatts.h.

ble_uuid_t const* ble_gatts_attr_t::p_uuid

Pointer to the attribute UUID.

Definition at line 227 of file ble_gatts.h.

uint8_t* ble_gatts_attr_t::p_value

Pointer to the attribute data. Please note that if the 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. For writable characteristics, this value must not be a location in flash memory.
