- Remove unused headers from examples - Improve periodic adv/sync example functionality and readability - Use ble_hs_id_infer_auto() instead of hardcoded BLE_OWN_ADDR_PUBLIC/RANDOM - Add ble_hs_util_ensure_addr() calls in on_sync for proper address setup - Use correct ext adv instance (0 instead of 1) in phy_prph, l2cap_coc, multi_conn - Fix struct name: ble_gap_periodic_adv_enable_params -> ble_gap_periodic_adv_start_params - Add CONFIG_BT_NIMBLE_GAP_SERVICE guards around ble_svc_gap_device_name_set - Fix unsafe AD data parsing with bounds checks in central examples - Fix UUID matching bugs (off-by-one loop condition and byte order) in phy_cent, htp_cent, and proximity_sensor_cent - Fix ble_multi_conn_cent address type to use dynamic inference - Remove contradictory sm_sc=0 after sm_sc=1 in ble_multi_adv - Add CONFIG_BT_NIMBLE_EXT_ADV=y to ble_multi_adv sdkconfig defaults - Check return values for ble_gap_set_host_feat, nimble_port_init - Update tutorials and READMEs to match code changes

BLE Channel sounding example
(See the README.md file in the upper-level 'examples' directory for more information about examples.)
- This example demonstrates the capability of the CS procedure to be executed on the ESP host + external controller.
- It is important to note that the current example does not provide support for distance calculation, and it is currently under development.
Example output
I (372) hal_uart: set baud_rate:115200.
I (382) NimBLE_RAS_INITIATOR: BLE Host Task Started I (382) main_task: Returned from app_main()
I (432) NimBLE: GAP procedure initiated: extended discovery;
I (157332) NimBLE: GAP procedure initiated: extended connect; I (157552) NimBLE: Connection established I (157562) NimBLE: Connection secured I (162222) NimBLE: encryption change event; status=0
I (162372) NimBLE: CS capabilities exchanged I (162372) NimBLE: Set default CS settings I (162392) NimBLE: create CS config I (162392) NimBLE: Setup phase completed
Note:
-
This example currently requires an external Bluetooth controller supporting BLE Channel sounding functionality,as the ESP chips listed above do not have native controller support for BLE channel sounding feature and is under development phase
-
To install the dependency packages needed, please refer to the top level README file.
How to Use Example
Before project configuration and build, be sure to set the correct chip target using:
idf.py set-target <chip_name>
Hardware Required
- A development board with ESP32/ESP32-C2/ESP32-C3/ESP32-S3/ESP32-C6 SoC (e.g., ESP32-DevKitC, ESP-WROVER-KIT, etc.)
- A USB cable for Power supply and programming
See Development Boards for more information about it.
Configure the Project
Open the project configuration menu:
idf.py menuconfig
In the Example Configuration menu:
- Change the
Peer Addressoption if needed.
Build and Flash
Run idf.py -p PORT flash monitor to build, flash and monitor the project.
(To exit the serial monitor, type Ctrl-].)
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
