Add characteristic parameters structure.
This structure contains the parameters needed to use the characteristic_add function.
| security_req_t ble_add_char_params_t::cccd_write_access |
Security requirement for writing the characteristic's CCCD.
| ble_gatt_char_ext_props_t ble_add_char_params_t::char_ext_props |
Characteristic extended properties.
| ble_gatt_char_props_t ble_add_char_params_t::char_props |
Characteristic properties.
| uint16_t ble_add_char_params_t::init_len |
Initial length of the characteristic value.
| bool ble_add_char_params_t::is_defered_read |
Indicate if deferred read operations are supported.
| bool ble_add_char_params_t::is_defered_write |
Indicate if deferred write operations are supported.
| bool ble_add_char_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_char_params_t::is_var_len |
Indicates if the characteristic value has variable length.
| uint16_t ble_add_char_params_t::max_len |
Maximum length of the characteristic value.
| uint8_t* ble_add_char_params_t::p_init_value |
Initial encoded value of the characteristic.
| ble_gatts_char_pf_t* ble_add_char_params_t::p_presentation_format |
Pointer to characteristic format if needed
| ble_add_char_user_desc_t* ble_add_char_params_t::p_user_descr |
Pointer to user descriptor if needed
| security_req_t ble_add_char_params_t::read_access |
Security requirement for reading the characteristic value.
| uint16_t ble_add_char_params_t::uuid |
Characteristic UUID (16 bits UUIDs).
| uint8_t ble_add_char_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_char_params_t::write_access |
Security requirement for writing the characteristic value.
