This sample is based on the ESPRESSIF ESP32 sample from https://github.com/azure-samples/iot-middleware-freertos-samples

To use this sample with Device Provisioning Service (DPS) and x509 certificates, follow these steps:

1. Generate and update the certificates in DPS

   Example of guideline to generate certificates: https://learn.microsoft.com/en-us/azure/iot-hub/tutorial-x509-openssl

2. Create an individual enrollment in your DPS, using x509 authentication and the device certificate generated in step 1

3. Set the kconfig configuration in this sample

   Run idp.py menuconfig (similar to instructions in the base ESP32 sample)

   Disable Use PnP in Azure Sample

   Enter your device id (from DPS individual enrollment) into Azure IoT Device ID

   Select X509 Certificates in Azure IoT Authentication Method

   Enter your device certificate (see instructions in the base ESP32 sample)

   Enter your device private key (see instructions in the base ESP32 sample)

   Enable Enable Device Provisioning Sample

   Enter your DPS ID Scope

   Enter your DPS individual enrollment device ID into Azure Device Provisioning Service Registration ID

4. Follow remaining steps in the base ESP32 sample to build, flash and monitor.
