Use the LE Secure Connections in the ble_thread_dyn_mtd_coap_cli example

[QuentinD]

Hello

My application is based on the ble_thread_dyn_mtd_coap_cli example which allows to use Thread and Bluetooth in parallel. I would now like to secure the bluetooth connection.
To do this, I tried to base myself on the example ble_app_multirole_lesc but I have a linking error:

Obviously, these crypto functions are defined in the 2 libraries.

If I don't add the libnrf_cc310_0.9.12.a library, then I have this as an error:

Do you know if it is possible to use Peer Manager with the ble_thread_dyn_mtd_coap_cli example? If not, how could I use LE Secure Connections in this example?

Thank you

Do you have any idea on how to implement bluetooth security on this example (ble_thread_dyn_mtd_coap_cli)?

Thank you

Hello,

The openthread examples are using the Nordic Security Module with the mbetls API, and because of this you have to select the nrf crypto mbedtls backend . But the NFC variant of the BLE UART and Thread MTD CoAP Client Example should support LESC pairing out-of-the-box, had you tried this example?

Best regards,

Vidar
