    • RE: Atom Echo. Format and create sound file

      I had really hope that someone could shed a light on this issue? Being a great product as it already is, its usability could be even more increased if some documentation about the binary format for the sound data is published.
      Really no one?
      Regards

    • Atom Echo. Format and create sound file

      I have been googling around, no understandable answers found. But I am sure I am not the only one with this interest.
      Could anyone explain the binary format of the sound stream used in the echo? And also nice to have : howto proces a mp3 or wav file into the required binary array to be used in the Echo?
      Thanks.

    • Paper for the Thermal printer

      Uh, what type of paper do I need to purchase for this printer? Is it somehow a standard package? Thank you.

    • RE: Unable to connect to AwS IoT Core with blinking app

      @ajb2k3 Thank you. After fully erasing the firmware I have executed again all the steps in the AWS getting started section. Again, same error about connection issue. The steps about Private key, Public key and region are not mentioned in the manual for Cloud connected Blinky.
      I should point out to that I was able te recreate the getting started example and are able to connect my rainmaker app on my iPhone with the AWS module. So that is at least a small step. I hope anyone can chip in.

    • Unable to connect to AwS IoT Core with blinking app

      Dear all.
      I believe I have follow all the steps as described in : https://edukit.workshop.aws/en/blinky-hello-world/blinking-the-leds.html Unfortunately the blink app is not able to connect to the AWS IoT Core. Please check the table of all the steps I have done. Have I missed something? Did I make a mistake somewhere? Help is appreciated. Regards

    • RE: Error: Detected a whitespace character in project paths.

      @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 ;-)

    • Error: Detected a whitespace character in project paths.

      So my first steps in setting up a project with M5Stack AWS on my Mac OSX Big Sur (11.6). Installation of visual studio seems okay. When compiling the AWS IoT EduKit Getting Started PlatformIO Configuration File I get this error message :
      Error: Detected a whitespace character in project paths.
      Been already googling around. Not sure about the solution. I have read that I need to change the director path in a ini file. But then I am lost. Any help? Thanks

    • RE: LORAWAN-UNIT-868MHZ-ASR6501 (still not working)

      @felmue Thank you for your response. I also came to the conclusion that this device is not suitable for LoRa PoP applications. That is really a pity. This one is suitable for LoRa PoP (I got that one working) : M5 LORA-MODULE-868MHZ. https://shop.m5stack.com/products/lora-module-868mhz?_pos=2&_sid=e21d4a90e&_ss=r

    • LORAWAN-UNIT-868MHZ-ASR6501 (still not working)

      Hello,
      Has anyone ever got tis device working for point to point communication between two of these devices. I have two atoms, attached to each such a device, I am able to communicate with the device through Serial2 port. But when sending a simpel string I continuously get the response : CME ERROR: 1. If I check the documentation (ASR650X AT Command Introduction), I see that the last line of the explanation of the DTRX command mentioned that "It is need to first join into the network, then send data later.". But in don't want to join any gateway? Can anyone help? Thanks
