Support of ESP32-H2

[VojtechBartoska]

This issue tracks support of ESP32-H2 SoC.

Support will be breakdown into subtasks later.

Main specifications of H2:
ESP32-H2 combines important connectivity technologies, such as IEEE 802.15.4 radio connectivity, which is vital to mesh architectures with low power consumption. ESP32-H2 also makes the Thread and Zigbee protocols available, thus addressing a variety of cases in application development. Furthermore, Bluetooth LE supports point-to-point, broadcast and mesh communication topologies, while it also enables the direct communication between a smartphone and an ESP32-H2-based device.

The combined availability of IEEE 802.15.4 and Bluetooth LE connectivity enables building devices for the Matter protocol, which intends to bring interoperability for smart-home devices.

Just out of curiosity: Is my understanding correct that this ESP32-H2 Soc would not feature any WIFI capability?
As much as I can read, this is not part of IEEE 802.15.4, right?

[me-no-dev]

correct @MacSass no WiFi :)

[Suxsem]

We are starting to see ESP32-H2 being sold on aliexpress at a reasonable price, it has the potential to disrupt the IoT segment with zigbee and matter-over-thread support. Arduino IDE support will be the sparkle to have this board becoming massively popular through makers, please think about adding it!

IMHO is the C6 way more interesting as it has both 802.15.4 and WiFi.

[VojtechBartoska]

@TD-er We will add support for both in Arduino ESP32 Core, C6 & H2.

[TD-er]

Great!
That means I could add support for both at the same time in my project.
Saves a lot of time.

I'd like to help w/this...

[VojtechBartoska]

@229311JK with what exactly? Support is available in latest Development 3.0.0-apha 3 release, you can test and use already ESP32-H2, we are working on the stable release right now.

working w/the ESP Thread/border Zigbee router V1.2... Will be in touch...

Been distracted w/the Esp32 programming board 4-the 32-C6 module. It's nice; Within the US, we have some excellent vendors to get hard to acquire Espressif HW.

Hello all
Is it available now?
Is there a way to test it?
I have a esp32-h2-mini-1 and would love to test it!

Follow the install steps in this page and you will be able to tested. I received mine last week an it worked like a charm.

Here you go: https://github.com/espressif/arduino-esp32/releases Now the hard part, scroll down & read. (Note, sarcasm meant 2-b funny & not mean...)

Did you get this squared away yet? Enjoy your H2...

I don t know how i did it, but i mixed two github projects… i wrote on the incorrect one…

this is the project :
https://github.com/tbnobody/OpenDTU

Sorry for inconveniance…

[VojtechBartoska]

Hello all,

version 3.0.0-stable was released yesterday and it includes support for ESP32-H2.

I am closing this ticket as solved and if you find any new issue related to ESP32-H2 chip, please open a new ticket.

Thanks for your contribution.
