      https://community.m5stack.com/topic/2454/online-uiflow-version-on-mobile-browsers-dissapearing-virtual-keyboard That bug is still there. This makes UIFlow on mobile browsers totally unusable. It is not even possible to enter an API key to connect to device

      @agreedk thank you for reply. I keep getting a compile error. A beep isn't totally needed in my project so i'm just going to leave it out.

      @raychmond Thanks for the update, It's been awhile sine I added the Core2 board manager so I don't remember which source I used. If I find it I'll update here. Thank you.

      Thanks to both :) @ajb2k3 : as written also by @felmue I want to power all my system with 3.3V so there won't be around any 5V at all ! Of course I need to check the specific schematic in order to understand what to bypass, but my question was if the white enclosure of M5Stack modules (like the I2C hub, or the heart rate sensor) can be easily open - without damaging / breaking them - or not (is there something like a screw?). Any clue about that? thanks!

      You can try this: https://www.google.com/amp/s/techtutorialsx.com/2017/10/02/esp32-micropython-creating-a-thread/amp/ But this may not work properly with all modules included in micropython firmware. You need also micropython version 1.14.

      @robalstona what do you mean by "check when the power button is pressed to power on device" ? I mean that this axp192 chip is always powered and waits for power button press to powering upthe esp32 chip and lcd with backligth. And check when this button is pressed for 6 seconds to shut down the power.

      Hi @anvalin , Sorry about that, since the M031-C module firmware version is relatively low, some AT commands do not match the AT user manual, so they are not supported yet.

      Thanks. I checked on the Core2 and here battery voltage also ranges from about 3.2V to 4.2V.

      So my last comment provided the solution.... The correct way of doing this is : 1/ Specify the Unicode character in the payload with chr(186) where 186 is the character number (in this case representing MASCULINE ORDINAL INDICATOR - Unicode: U+00BA, UTF-8: C2 BA. 2/ Ensure that your json.dumps applies utf-8 encoding before sending it to MQTT as follows: m5mqtt.publish(topic, json.dumps(payload).encode('utf-8')) Problem solved.

      In UIFlow you need to use the Set HV block to before screen draw before powering the coreink off otherwise you get the fading on shutdown.

      @world101 So I figured it out: On that particular module I connected it as follows: Left pin on module labeled 'S' to 5v on the righthand side of M5Stack (red wire) Center pin on module (not labeled) to GND on the righthand side of M5Stack (yellow wire) Right pin on module labeled '--' to pin 2 on the righthand side of the M5Stack (orange wire) After you compile and upload the app tap the module to see the "Tap" message.

      Measure force on M5StickC through PbHub with Weigh Module?

      For my particular project I have a 8 digital IO that I am trying to connect and therefore would like to use the PbHub connected to the M5StickC to expand the IO (as they advertise). I also have the weight module which works fine if I connect this directly to the M5StickC grove port. So now I must choose between using a PbHub or a Weigh module. I had thought it possible to add the weigh module to one of the ports on the PbHub however after experimenting with different pin combinations for initializing the HX711 scale i.e. HX711 scale(33, 32); // This works when the weigh unit is connected to the grove port on the M5StickC // Below are the other combinations I tried for passing the necessary pins to the HX711 through the Mega328 without any success. //HX711 scale(porthub.hub_d_read_value_B(4), porthub.hub_d_read_value_A(4)); HX711 scale(porthub.hub_a_read_value(4), 32); //HX711 scale(porthub.hub_d_read_value_A(4), 32); //HX711 scale(porthub.hub_d_read_value_B(4), porthub.hub_d_read_value_A(4)); //HX711 scale(porthub.hub_d_read_value_A(4), porthub.hub_d_read_value_B(4)); Unfortunately, I think @felmue is right. The Mega328 isn't able to forward the clock required by the HX711 chip.

      This does not need a "revision" or "V2" model, it's a simple software addition. And you can already load your own fonts if needed.

      1st thing to do is DON'T Panic! Next remove the base and module leaving only the firecore. Plug a usb cable in and connect just the core section into a computer, go into hardware reports and check usb devices. Do you have a USB to UART adapter? Try the instructions on this page to use an external adapter https://docs.m5stack.com/#/en/tool/usb_downloader?id=esp32-downloader

      @felmue Tried both. 3.3V has a bit higher current. Strange, if there's just an LDO (guessing - no schematics!). Also removed IR and RGB LEDs. Tried with Arduino and Espressif IDF deep-sleep example. No success. NodeMCU with Wroom32 is kind of OK (1.6mA), by the way. But mechanically too large ...
