Tasmota Support for ESP32-C6/C2 (Arduino 3.0 based on IDF 5.1)

[Jason2866]

This needs porting Tasmota from Arduino ESP32 v2.0.14 (IDF 4.4.6 based) to the new Arduino 3.0.0 (IDF 5.1.3 based). Zigbee and Thread support will not part of the Arduino 3.0.0 release

Tasmota porting work is done (Thx @s-hadinger, @Staars, @gemu2015 and @arendst ).
EDIT: Port to Core 3.0.0 beta needed. The wifi / network part has been completly refactored. Tasmota crashes.

The Tasmota development branch is using Core 3.0.0 since April 15th 2024

Working

• Berry (tested with Partition Wizard)
• I2C
• changed BLE driver
• OneWire (tested with one DS18B20)
• PWM (checked with 3 LEDS (RGB))
• Serial Console (Serial and CDC)
• Very early NEW RMT Neopixel driver
• SD Card
• uDisplay
• OTA update / safeboot
• Webcam
• Ethernet (LAN8720 tested, JL1101 tested)
• I2S Tasmota Audio (tested ttgo watch, M5 core2)
• DAC Audio
• Matter
• IPv6
• eMail
• IR (IRremoteESP8266 library)
• Shutters (tested)
• AC Zero Cross dimmer

deprecated (feature will not be ported):

• Homekit (already removed)

todo:

• WiFi Range extender -> Range Extender driver xdrv_58_range_extender does not compile with core 3.0.0 #21200
• wifi and network crash with 3.0.0 beta
• Porting "Scripter"
• uDisplay driver crashes with C3 when using filesystem
• uDisplay driver glitches with S3 and big display (content "shifted") NO Tasmota issue-> workaround via sdkconfig
• I2S Mic (Recording)
• I2S port to new API (affects everything using I2S)
• complete Audio stuff (I2S based)
• I2C drivers function tests of all drivers (general function checked with BME280)
• Hue and WeMo Emulation testing
• Test new RMT Neopixel driver
• IPv6 testing
• eMail testing
• IR testing
• Tests and more Tests for not mentioned stuff

Tests and feedback is welcome in this discussion (do NOT open an issue). The Tasmota Arduino 3.0 versions can be compiled with branch development with enabling the wanted build in file platformio_tasmota_core3_env.ini The file will be generated when building any other Tasmota version

[sfromis]

It would be "interesting" if the Tasmota support for the C6 also includes this Wi-Fi 6 feature:

Additionally, the Target Wake Time (TWT) feature of the 802.11ax standard enables ESP32-C6 customers to build battery-operated connected devices that can last for years, while staying connected throughout.

[Jason2866]

TWT is not (yet?) supported in Arduino code.

[VojtechBartoska]

Hi, we did some progress on Zigbee support in Arduino Core 3.0.0, take a look on this issue espressif/arduino-esp32#8807, related pull request are part of 3.0.0-alpha3 release.

[s-hadinger]

Thanks, excellent news. We don't have short term plan for Zigbee Coordinator in Tasmota, but it would be interesting to see if we can do a Zigbee end-device. Do you have code examples on how to run a ZIgbee end-device with Arduino Core 3.0?

[VojtechBartoska]

@P-R-O-C-H-Y will soon add ported examples from https://github.com/espressif/esp-idf/tree/master/examples/zigbee/light_sample to Arduino to demonstrate some basic function.

[s-hadinger]

Great. It's still unclear to me how Zigbee and Arduino event loops coexist. I suppose they run in two separate FreeRTOS tasks.

[rena2019]

@P-R-O-C-H-Y will soon add ported examples from https://github.com/espressif/esp-idf/tree/master/examples/zigbee/light_sample to Arduino to demonstrate some basic function.

which issue do I have to follow to find these examples?

[VojtechBartoska]

Hi, this one: espressif/arduino-esp32#8807

[kroon040]

Hi

I tried to compile for the esp32c6, but it fails

[Jason2866]

@kroon040 Thx for the info. Scripter is not yet Arduino core 3.0.0 ready. Remove Scripter from your setup and it should compile successfully.

[kroon040]

You are right, now it compiles. Now waiting for scripter is working

[Jason2866]

Thx @gemu2015! Fixed with already merged PR #20895
@kroon040 You can test with latest development

[kroon040]

It compiles. I flashed the chip later

[kroon040]

I flashed the chip and works. I also see in the router that it uses the 802.11AX (g-HE) High efficiency. In the information of tasmota I see still mode 11n, maybe also possible to see if it connects with ax?

I used this chip

[Jason2866]

@arendst It should be possible to query the established connection type. There is an IDF API call for
esp_wifi_sta_get_negotiated_phymode https://docs.espressif.com/projects/esp-idf/en/stable/esp32/api-reference/network/esp_wifi.html#_CPPv421esp_wifi_get_protocol16wifi_interface_tP7uint8_t
