Hi @Alexey ,

Great to see all the new features in 1.15.0! I am excited to give it a whirl.
Does anyone else experience ESP_ERR_MBEDTLS_SSL_HANDSHAKE_FAILED when connecting to Azure IoT Hub? This does not happen on 1.14.3


Hi @jeetland,
I tested the Gateway firmware v1.15.0 to use MQTT with Azure IoT Hub and found no issues.
I configured the Client on the server side to use self-signed certificate by enabling “Thumbprint Match” Validation scheme:

And here is the gateway configuration:

Don’t forget to fill MQTT “Username” on the gateway, it should be equal to “Client Authentication Name” parameter on the cloud.

  • Fixed a bug where the network watchdog timer timeout was disabled in configuration mode.
  • Addressed a race condition causing the gateway to restart after erasing the configuration.
  • Improved UI detection of gateway reboots when password protection is disabled.
  • Corrected the LED behavior to prevent it from remaining solid green when the configuration mode deactivates after a timeout.
  • Fixed a crash on WPS restart due to an uninitialized pointer in the wpa_supplicant component.
  • Corrected HTTP HEAD request failures due to race conditions on slow servers lacking HTTP Content-Length headers.
  • Enabled the use of TLS v1.2 for Azure IoT Hub connections, preventing SSL handshake failures.
  • Implemented a dynamic delay after encountering a Wi-Fi MIC_FAILURE connection problem.
  • Corrected the decoded TXPower value.
  • Fixed HTTP endpoint validation issues when a 204 status code is returned.
  • Prevented web browsers from remembering API keys.
