Sample DTLS client implementation with mbedtls

This is a DTLS client sample in C that uses the mbedtls library. This is a library used in both Zephy, ESP-IDF and other projects.

Client certificate and private key

The sample code reads the certificate and private key from the files cert.crt and key.pem. Both files must be PEM-encoded. The cert.crt contains the client certificate, intermediates and root and the key.pem file contains the private key.

Use the span CLI to generate a certificate and key file.

Building on Raspberry Pi

This example buidls on Raspberr Pi (including Zero) - run sudo apt-get install libmbedtls-dev to install the mbedtls headers, then make to build to example.
