C6 will not be supported until ESP-IDF 5.1, so arduino will not support it until that is released.

[VojtechBartoska]

Hello, support of ESP32-C6 is on our Roadmap, @lbernstone is right that it will be supported in ESP-IDF 5.1 so in Arduino, it will be in version 3.X.X. We'll soon create development branch and we will start working on IDF 5 support there.

@probonopd Thanks for opening the issue, we will use it to track progress on support of ESP32-C6 :)

[tuct]

My first esp32 c6 dev boards v0.0 arrived today, eager to test it!

[simogaspa84]

Hi @tuct how did you get it the esp32 c6 dev board? which supplier ? thanks

[negis02]

mine also just arrive, i ordered from there: https://www.aliexpress.com/item/1005005125343088.html?spm=a2g0o.order_list.order_list_main.29.28e41802T3MZjD

[simogaspa84]

Thanks a lot @negis02 .. very kind... are you going to try the new features about cyber security in the C6 dev board?
I am really interested about the trusted execution enviroment and the glitch detector.. Do you know something about that?
Thanks

[seajhawk]

Hey @simogaspa84 - thanks for posting.
I'm mainly interested in the Thread support, but I'll have to look at the trusted execution and glitch detector features. I wasn't even aware of those!

I'm building an air quality, temp, humidity, CO2 sensor.

Does anyone know if we can use a C3 board for basic prototyping until the C6 support is added?

[tuct]

I got mine from the official store at aliexpress

I bought 5, so the limit is new, happy to share of you are close to or in Vienna

[negis02]

For me most interesting to try ESP32-c6 in Wi-Fi 6 network, to test all WiFi6 benefits: in some application test and compere real time messaging over Wifi6 in is heavy loaded Wi-Fi with many devices, like MU-MIMO and OFDM AP capability tests with IOT device like this;
and another test: battery life: Wifi6 wake-up timers test with esp32-c6.

[Trevo525]

You can also purchase from Adafruit's official store. They have 47 in stock at the time of writing this.

46 now, I bought one. 😝

[a-d-r-i-a-n-d]

I've ordered mine today, looking forward to C6 support.

[MingyaoLiu]

I just got my esp32-c6 wroom module, looking forward to have arduino capability!

[guumeyer]

I just got my esp32-c6 wroom module too, looking forward to have arduino capability!

idf.py --version
ESP-IDF v5.1-dev-3710-gacac972f70

It looks like v5.1 has been released ;-)

[me-no-dev]

It has not. This is just the version that will be used in the future. 5.1 is in ESP-IDF master and needs to be split in it's own branch before it will be released. It has not even been feature-frozen yet :)

[noonien]

Any update on this?

[djmjr77]

Update please?

[me-no-dev]

Guys, please stop asking for update every few days. Before we add support for new chips, there is a lot of work that needs to be done. When that is done (will take way more than few days) most if not all new chips will be supported. We will announce that, so even less reason to keep asking.

@probonopd Thanks for opening the issue, we will use it to track progress on support of ESP32-C6 :)

As noted, the official Espressif ESP-IDF v5.1, which is currently in development, will include initial support for the new ESP32-C6 chip, however, while Espressif ESP-IDF v5.1 has not yet been released it should mostly work if using the master branch in esp-idf repository. If you want to track the development status then follow these the updates made to these other issues for ESP32-C6:

[LenReinhart]

Another waiting for C6 support. Subscribed.

[Jason2866]

@maxdd There is probably no easy answer possible. It depends how fast is the switching between wifi and zigbee. If this is implemented well, there is a chance wifi and zigbee performs really well with no really performance penalty. If this happens not smooth performance will be horrible. Real world usage examples will show.
Imho espressif has to deliver a zigbee coordinator Firmware which shows the power of the C6 in this use case. Before this happens it is a paper tiger, no one really will make a commercial product with. There are too many good alternatives already which can be choosen.

[simogaspa84]

Hi guys news about C6 support in platformio ? How is going the integration process? Thanks

[TD-er]

When using the platform_packages made by @Jason2866 you can use the C6 perfectly fine.
I've been working on the C2/C6 for a few months now and all features already present in the other modules, including wifi6 (802.11ax) are working just fine.
I haven't tested the 802.15.4 yet, so can't speak about it from experience.

[simogaspa84]

Hi @TD-er can you copy ini the platformio.ini file to use Esp32-c6 with platformio and arduino framework? Thanks a lot

[TD-er]

see: https://github.com/letscontrolit/ESPEasy/blob/mega/platformio_core_defs.ini

and newer builds made by Jason:
https://github.com/Jason2866/esp32-arduino-lib-builder/releases
You need the release/v5.1 ones as platform_package
and pay attention to use the ones without "solo1" in the name

[Jason2866]

Build from yesterday. Complete setup just use this

 platform = https://github.com/tasmota/platform-espressif32/releases/download/2024.01.11/platform-espressif32.zip

I can't seems to get to work ESP32-C6 with Arduino IDE 2.3.2 using Alpha3 Board Library from Dev channel https://espressif.github.io/arduino-esp32/package_esp32_dev_index.json

I installed alpha3 to Arduino IDE, selected ESP32C6 board. I created a super simple sketch, no external libraries. Compilation and upload are OK but there is nothing coming out of ESP32 on Serial port.

void setup() {
  // put your setup code here, to run once:

}

void loop() {
  // put your main code here, to run repeatedly:
  Serial.println("Hello world");
  delay(1000);
}

If I compile this example (in C) or an example from ESP-IDF, compile it with idf.py build and upload it to ESP32-C6 then it works OK. It must be something with Arduino IDE. Is there another step required after installation and selected of the board in Arduino IDE?

[TD-er]

What is your "Serial port"?
Do you use an USB to serial chip or is the USB connector connected directly to the ESP32-C6?
If you are using this "native USB" serial port you need to enable to use the HWCDC port.
Maybe there are also board definitions which have this already set, so you then only need to select a different board.

I think you forgot to call something like "Serial.begin(115200)" in your setup function.

If you are using this "native USB" serial port you need to enable to use the HWCDC port. Maybe there are also board definitions which have this already set, so you then only need to select a different board.

I have a problem similar to gtom84. I have the ESP32-C6-DevKitM-1 board and I've added Serial.print s to the Blink example, with boards selected from the 3.0.0.a library. I'm using the USB connector and uploads are OK so I think the basic connection is good. Depending on which board is selected, I can get the LED or Serial to work, or neither works, but not all the same time.

It should be simple to fix the LED problem, but I haven't succeeded yet. Would say the native port is already enabled? If not, how do I do that?

[slaesh]

facing an issue with the async TCP connection, at least I guess so. pretty complex project, trying to strip it down.

basically what happens:

connecting to an mqtt broker via WiFi connection. working fine. sending a message every few seconds, no problem. receiving messages works too. unless, after a period of time (yet unknown) receiving a message crashes the esp and it restarts.
message is bot being processed, no logs being printed in any callback. (added delays to ensure it would be printed). it's still sending messages, but after not received messages for a longer period and then receiving one makes problems.

trying to break it down to a minimal code basis :)
anyone facing similar issues?

using the asyncmqttclient which uses the now built in "esp async TCP" library.

EDIT: same code works on another esp32 flawless for several months :) esp32-pico-v3.

[Jason2866]

@slaesh Only can say Tasmota works stable with the C6 (test run a few days) no crash or reboot. Tasmota uses mqtt (modified pubsubclient) by default. There was a BME280 sensor connected, providing sensor data every 5 minutes via mqtt.

[TD-er]

Also ESPEasy works fine on the C6 with MQTT and some sensors connected.

[slaesh]

thanks @Jason2866 @TD-er , works now fine. had a weird mis-configuration somehow. was going to a newer platform_packages build and got weird compile time errors like saying that the WiFiEvent_t type is missing and other stuff.. after completly removing and re-installing platformio and all deps it went away.. Oo dunno what this was, but now it works as expected! :)) thanks for your feedback, so I could narrow it down faster :)

[probonopd]

Cool. Is there zigbee support and an example?

[VojtechBartoska]

@probonopd ported ESP-IDF examples to Arduino are here: https://github.com/espressif/arduino-esp32/tree/master/libraries/ESP32/examples/Zigbee

Will it be available through a package update soon?

Hi,

I also run tasmota with and esp32-c6. It connects to g-HE (AX), but I noticed ping from a client to the esp32c6 I got a ttl of 63 instead of 254? @Jason2866 is this also with your device, and is it tasmota of arduino related?

[TD-er]

What do you mean by a TTL of 63?

Not sure if this also applies when connecting via AX (thus HE instead of HT), but I also have set this in my (ESPEasy) code:

  // HT20 = 20 MHz channel width.
  // HT40 = 40 MHz channel width.
  // In theory, HT40 can offer upto 150 Mbps connection speed.
  // However since HT40 is using nearly all channels on 2.4 GHz WiFi,
  // Thus you are more likely to experience disturbances.
  // The response speed and stability is better at HT20 for ESP units.
  esp_wifi_set_bandwidth(WIFI_IF_STA, WIFI_BW_HT20);

This bandwidth enum does only have HT20/HT40.

I noticed that ESP32-xx does perform less 'snappy' when using HT40.
So maybe this also does help something when you may experience poor response when connected via AX?

I did add WiFi 6 support after setting this bandwidth limitation so I never tried without.

[Jason2866]

@kroon040 i have no wifi 6 equipment

[kroon040]

What do you mean by a TTL of 63?

Here exmapl of 3 devices , the last with esp32-c6, all with tasmota .
Fist is a normal esp32 device

64 bytes from 192.168.170.68: icmp_seq=4 ttl=254 time=8.09 ms

An esp32-c3 device

PING 192.168.170.35 (192.168.170.35) 56(84) bytes of data.
64 bytes from 192.168.170.35: icmp_seq=1 ttl=254 time=3.00 ms

64 bytes from 192.168.170.35: icmp_seq=3 ttl=254 time=2.75 ms

The esp32-c6 device

ping 192.168.170.103
PING 192.168.170.103 (192.168.170.103) 56(84) bytes of data.
64 bytes from 192.168.170.103: icmp_seq=1 ttl=63 time=36.6 ms
64 bytes from 192.168.170.103: icmp_seq=2 ttl=63 time=60.2 ms
64 bytes from 192.168.170.103: icmp_seq=3 ttl=63 time=80.5 ms

[Jason2866]

Looks like a different setting choosen for TTL with the C6. Will have no impact in real life.
The high ping times in relation to the other devices is something which is not good.

[TD-er]

I hardly ever pay attention to the TTL of ping.
I only use it for traceroute/tracepath kinda stuff as that's using the TTL of a ping to get some idea of the route a packet takes to reach some host.
On each 'hop' the TTL is decreased with 1 (typically) and as soon as the TTL reaches 0, it is discarded.
I have no clue why it is set to 63 here as I doubt it has already taken 192 hops to reach your ESP and I assume you did do these pings from the same machine?
If not, then that's probably your answer as the initial TTL value can be different from platform to platform.

I doubt any hop on the route to your ESP will 'restart' the TTL at some much lower value like 128 or 64 as this can mess with tools like traceroute/tracepath. (though I doubt you will ever need more than ~30 hops to reach anything)
