Can I send the temperature sensor data to AWS IOT cloud using ESP32H2 and Homepod? (CON-1478)

[GayathriHommi]

I am using ESP32h2, a temperature sensor, homepod and I'm using esp-matter code example- sensors for sending the temperature data to Homepod home application. I want to send this temperature data to AWS iot cloud through VScode can i get any reference code or documents

@GayathriHommi Please check out this repository for a head start: esp-rainmaker-common.
For more information related to MQTT with ESP-IDF, you can refer to this documentation. A similar approach can be implemented with ESP-Matter as well

Hi, @GayathriHommi you can connect the ESP32-H2 to the cloud server with Homepod as the Apple Homepod supports the NAT64 feature. To use this feature your need to enable the following options in menuconfig:

CONFIG_OPENTHREAD_DNS64_CLIENT=y
CONFIG_LWIP_HOOK_DNS_EXT_RESOLVE_CUSTOM=y

After that you can use the common APIs to access Internet.

@GayathriHommi Please close the issue if it has been resolved.

@wqx6 while trying to connect esp32h2 to aws iot i'm facing some issues but the same code is working fine with esp32s3

esp-tls: couldn't get hostname for :a1q5vtttjz7alq-ats.iot.ap-south-1.amazonaws.com: getaddrinfo() returns 202, addrinfo=0x0
E (90334) esp-tls: Failed to open new connection
E (90334) transport_base: Failed to open a new connection
E (90344) mqtt_client: Error transport connect

Are there any more changes to be made other than this
CONFIG_OPENTHREAD_DNS64_CLIENT=y
CONFIG_LWIP_HOOK_DNS_EXT_RESOLVE_CUSTOM=y
