  @felmue Yes thank you. I never realised that in one of my folder names I had used a white space (maybe I really need reading glasses). Now I am struggling to get my AWS blink setup and running. Will come back later with a detailed description of my challenge ;-)

  Yes, there is a newer repository that has rust bindings for FreeRTOS/ESP-IDF by Espressif themselves: https://github.com/espressif/rust-esp32-example The blog that @flypeek shared is using that library with other libraries that seem to be able to access some of the peripherals on the device. Note that many of the features are not available or will need to be modified since the blog is on the older M5Stack devices. I would love to see a more robust port and example with all/most of the features working—would be a fun project. I'd love to promote it on the AWS IoT EduKit Content Library.

  Seems like the message coming from the device over the serial port is malformed for some reason. Have you tried switching to a different cable?

  There is a bug in uiflow execute block. When you click to edit text of this block, there is a one space before cursor. With this space your code throw bad intendent error. Simply press backspace before write your code to delete this space.

  Please see: https://github.com/m5stack/Core2forAWS-MicroPython for an example using the ATECC608 when establishing TLS to the AWS IoT Core MQTT broker.

  Hi @KristheTech, to make this work, you'd need to do a few things: You'd need to read the image data and store it into a buffer the size of the resolution and image density. Send the image data as a MQTT message (you can use the Blinky Hello World example). Keep message at/under 128kb. Set up an AWS IoT rule to save each message into an S3 bucket. Have Amazon Rekognition read from that same S3 bucket. Do something with the output from Rekognition.

  Hi Pradeep, different hardware will have different pin assignments. Your sensor should be connected to Port B if it's using the ADC and pinTempSensor should be set to pin 36.

  Hello @felmue, you are right, the top of M5Core2 and the AWS are identical. But the bottom is the challenge: The ground of the AWS shields the antenna. -> Yes, I tried the AWS version without the AWS M5GO2 bottom attached. I tried this too: Insert a prototyp board between AWS-top and AWS-bottom. It improves the field strength a little bit. Insert a small silver wire in the prototyp board at the antenna of the AWS-top. So I almost reach the regular field strength.

  There are pin differences for some of the features, but yes you can disable the atecc608 part of the code.

  Hi @infinitool , So when you unplug/plug the device in, the serial port doesn't even show up? If the port does not show up on your computer, then there are other issues. You can see these instructions or the link to Espressif's documentation for identifying the port for each OS: https://edukit.workshop.aws/en/blinky-hello-world/device-provisioning.html#identifying-the-serial-port-on-host-machine You can use PlatformIO. As a matter of fact, the Getting Started guide explicitly uses PlatformIO: https://edukit.workshop.aws/en/getting-started.html.

  @vgamlc, can you describe what you are wanting to see? The Sk6812 (side LED bars) has a few methods you can use (take a look at components/core2forAWS/core2forAWS.h from one of the projects): void Core2ForAWS_Sk6812_SetColor(uint16_t pos, uint32_t color); void Core2ForAWS_Sk6812_SetSideColor(uint8_t side, uint32_t color); void Core2ForAWS_Sk6812_SetBrightness(uint8_t brightness); void Core2ForAWS_Sk6812_Show(); void Core2ForAWS_Sk6812_Clear(); If I want to set the left LED bar to yellow example, you should put the following into your application: Core2ForAWS_Sk6812_SetSideColor(SK6812_SIDE_LEFT, 0xFFFF00); Core2ForAWS_Sk6812_Show();
