I think I probably have a defective unit. I have tried with only a single tab open, latest version of Google Chrome, tried it incognito mode also just to be sure some extension wasn't getting in the way. Despite all efforts it never connects to UIFlow. I know it's on the network because my router is showing it connected and sending/receiving some packets.

I will probably stick with devices that have USB-C on them, this is way too much hassle and I don't want to have to rig up a programmer just to toy around with a prototyping device. Oh well, at least I'm only out $5.

Ok so the green pulsing light means "Normal, connected, ready for UIFlow"?

As you can see I'm not doing anything especially exotic or weird here:

How it looks when I click the Run button in UIFlow:

How it looks when I click the Download button and let the app run on its own:

I reset the unit, went to the captive portal, set my SSID and password and it connects successfully to my network. I can see that it is transmitting data on my router control panel. The light is pulsing green.

But when I try to connect in flow.m5stack.com it fails. I have carefully checked the MAC address, verified it on my router, and made sure I typed it in correctly. I've also tried resetting the device, reloading UIflow but nothing seems to help.

What's the trick to getting one of these m5stack esp32 pico devices to connect to UIFlow?

@rashedtalukder Congrats, hope you are on to somewhere that appreciates your skills!

@ajb2k3 It's super buggy. I tried getting this ATECC608 chip working with Arduino code and had very inconsistent results, kernel panics and crashes. The only way I've seen it run consistently is by running the RTOS code in the AWS edukit tutorials.

Wow, your balancing star is impressive!

I'm just playing around in UIFlow to see what's possible with this device.

I wrote a small program to print out the IMU X, Y, and Z accel values to the serial port.

It seems the readings can be pretty erratic, jumping from near zero to 0.4 or 0.5 even when the device is completely still.

How do you all deal with this? I tried taking the average of the last 5 readings which seems to help a little but it's still kind of jumpy.

Have a look. This is sitting completely flat on the desk:

When you copy this block and change the color, it makes pixels white:

When making animations you always want to copy the previous frame. This is inconvenient because every block must be created from scratch.

Has anyone else observed this? When I have a button handler the first time I click it doesn't get detected. But subsequent presses work fine. This happens for short, double, or long clicks consistently.

@felmue I think I found the issue; my deepsleep() call was inside a loop. Moving it outside the loop sorted it out.

This does not work:

But this does:

For some reason you have to hard-code the string of the local file path, this handler won't accept the variable and produces an error:

OSError [Errno 2] ENOENT

This Azure handler won't play cloud based wav files. The play_local works fine though. The error message shown when trying to play a WAV URL is below:

Unhandled exception in thread started by <bound_method>

In case anyone else has the same issue...the handler works if you hard-code the path to the Wav file

but cloud path doesn't work with the same trick, it still gives the Data format is not valid error.

I also tested this with a local file but get a different error:

OSError [Errno 2] ENOENT

I added it to my model so you get a UI field in Azure now for pasting in the cloud wav file URL:

The command gets to the device but it can't parse it for some reason, get a Data Format Invalid error.

Anyone know what to put here for the Payload? I want to play a sound with the play_cloud command.

@hwtaro9 makes sense. The battery is tiny, probably only useful for small toy drones or maybe low power LCD displays
