BLE Channel Sounding reflector 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.
Ble channel sounding reflector example uses the RAS service defined in ble_svc_ras.c

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 (157562) NimBLE: GAP procedure initiated: extended advertise; instance=0

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: Setup phase completed

To test this demo, any BLE channel sounding initiator app can be used.

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.

Before project configuration and build, be sure to set the correct chip target using:

bash

idf.py set-target <chip_name>

Open the project configuration menu:

bash

idf.py menuconfig

In the Example Configuration menu:

Select I/O capabilities of device from Example Configuration --> I/O Capability, default is Just_works.
Enable/Disable other security related parameters Bonding, MITM option, secure connection(SM SC).

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.
