I also connected GoPlus 2 to M5 Basic. Next, I connected Relay Units to PortB_1 and PortB_2 respectively and confirmed the operation. UIFlow Block is based on the image posted by ajb2k3_san. I didn't have to use a block of Relay Units.

@bwubs No, they wont work as you need an I2C hub as @felmue points out.

You have to convert the image to indexed websafe before saving and converting to a c array. This can be done in both GIMP and illustrator.

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.

@m5stack I'm trying to use M5StickC with USB mode from M5Burner. But I can't change because I got this error. First this message will pop and I chose "Continue". Then this error occurs and I cant change the mode. How can I fix this? Regards,

I figured out how to work the Core2 for AWS LED strips. Add a custom RGB LED Unit with custom port. SDA/TX is on 25, and SCL/RX on 22. The Number of LEDs is 10. Then set the neopixel device as you want it. LEDs 1-5 are the right side, and 6-10 are left. Remember to also Enable the bus power mode.

@plusulli I will investigate, thanks a lot

Hello @microdynasty I wouldn't count on it to be added anytime soon (if at all) to UIFlow. If you'd like to use your LAN module I suggest you look into Arduino programming. Why do I think that, well... a) The official documentation for the LAN module doesn't mention UIFlow. b) Lately M5Stack has not proven themselves as being very keen or quick to fix reported issues of functionality which worked in the past but got broken in recent versions of UIFlow. So I would be very surprised if they find the time to add (old) stuff. Thanks Felix

@silvereq thank you very much for your information i will update the instruction and btw, i am almost finished with a modified version of the code so that you can insert a config text file onto a sd card wich only has to contain the wifi-settings, timezone, pairs and the color of its name. I will updatede https://github.com/frittna/Crypto_Coin_Ticker soon. It will then be much easier to "burn" the compiled app into the M5 and nobody needs to compile on its own if he is not intended to change or improove the bitcoin price ticker thx!

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.

I've been trying to get this to compile/install using the Arduino IDE and i'm not getting anywhere... Once installed, the M5Paper just continuously reboots, flashing the screen on and off. Watching the serial monitor I see this repeated on each reboot... Any suggestions? Rebooting... M5EPD initializing...OK Guru Meditation Error: Core 1 panic'ed (LoadProhibited).

I just finished to adopt the example at https://github.com/m5stack/M5Stack/blob/master/examples/Unit/THERMAL_MLX90640/THERMAL_MLX90640.ino in Arduino IDE to Core2 and it works fine. If you are interested I can share the code.

@leo05 said in External WiFi Antenna?: @lukasmaximus Same here - We are using Fire or Core2 + Arduino. In dense environments (a lot of WiFi AP) device simply cannot connect or disconnects after a minute or two. Our options: 1. Add antenna somehow (with some soldering or whatsoever) 2.Add the additional WiFi module with antenna 3. Use other device. Any thoughts?

@m5stack it's been 3 weeks, without even a confirmation that you've read the issue. Could we please get an update? Or maybe @Zontex, you could bug someone at M5 HQ, since you seem to be more active.

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.
