Add descriptor parameters structure.
This structure contains the parameters needed to use the descriptor_add function.
uint16_t ble_add_descr_params_t::init_len |
Initial descriptor value length in bytes.
uint16_t ble_add_descr_params_t::init_offs |
Initial descriptor value offset in bytes. If different from zero, the first init_offs bytes of the attribute value will be left uninitialized.
bool ble_add_descr_params_t::is_defered_read |
Indicate if deferred read operations are supported.
bool ble_add_descr_params_t::is_defered_write |
Indicate if deferred write operations are supported.
bool ble_add_descr_params_t::is_value_user |
Indicate if the content of the characteristic is to be stored in the application (user) or in the stack.
bool ble_add_descr_params_t::is_var_len |
Indicates if the descriptor value has variable length.
uint16_t ble_add_descr_params_t::max_len |
Maximum descriptor value length in bytes, see Maximum attribute lengths for maximum values.
uint8_t* ble_add_descr_params_t::p_value |
Pointer to the value of the descriptor
security_req_t ble_add_descr_params_t::read_access |
Security requirement for reading the descriptor value.
uint16_t ble_add_descr_params_t::uuid |
descriptor UUID (16 bits UUIDs).
uint8_t ble_add_descr_params_t::uuid_type |
Base UUID. If 0, the Bluetooth SIG UUID will be used. Otherwise, this should be a value returned by sd_ble_uuid_vs_add when adding the base UUID.
security_req_t ble_add_descr_params_t::write_access |
Security requirement for writing the descriptor value.
