It sounds like the Core2 isn’t maintaining a stable connection with UIFlow. A few things to try:

1. Reflash the firmware with the latest stable UIFlow_Core2 version using M5Burner, and ensure "Internet Mode" is selected. 2. Double-check that the Device Name/API Key in UIFlow matches what's shown on the Core2 screen. 3. Disable any firewalls or antivirus that might block the connection. 4. Try using UIFlow Desktop IDE instead of the web version for better stability. If issues persist, test on another PC to rule out local system conflicts.

@wwhite Did you plug the UNIT into the red socket on the left side?
These inputs are: 21 and 22.
You could plug it into the discrete I/Os around the base on the right side where you will find 26 and 36.

Hello @wrs642

from this and your previous post I would guess that there is no battery connected or it is not charged (enough).

Thanks

I am also trying to get RFID 2 to work with PaHub and running into similar problems:

How to work with I2C device that requires initiation ahead of time. In this case, it is

MFRC522 mfrc522(0x28);

Why 0x28 show up in CH0 readout while RFID 2 is plugged into CH1 on PaHub.

You mentioned to get an update version of ClosedCub.cpp? I don't have the directory in my library folder, could you please be more specific. (I also googled it but out of luck there as well).

Thanks,

@gantini The sensor is a capacitive sensor and so the higher the reading the lower the moisture level.
These are superior to the resistive sensors that rot easy but work the same way.

@NickMaddock Howdy. I know this thread is old, but I just got a couple of these units thinking they would not be hard-wired terminated, too. I guess the lesson for me is to read the schematic even when it seems apparent that you would not want these always to be terminated on each unit.

Were you able to find a way to make these work how you wanted? I noticed in the demo video that you could have more than two devices hooked up and that they have two rollercan units connected to an M5Stack Core. Since there is no other documentation, I am assuming that the Core is not terminated, and thus, the three devices shown in the demo video would work together with no issues.

Unless there is an easy way to hook these up non-restrictively, I am glad I did not buy more than two. The motors seem nice in every other way,

Hello @drbob

my example should give you a head start. Please have a look here.

Thanks

I, too, am looking for clear-cut information on how to update the firmware on several devices using the STM chips on the Unit itself.

I've searched most of the GitHub repos, done web searches, and asked my AI buddies for help, but nothing is directly related to M5 devices.

@robski Yeah I had seen that behavior with it jumping to the right address and then crawling after not finding it.

@robski :

Edit: The address conflict is not with the ENV IV units, but with something else - either way I must remain on UIFlow 2.

I checked with two additional controllers: Atom matrix, and Stick C plus : The same issue.

However, odly I am able to "fool" the controllers for a brief timeperiod by going through a very particular sequence in Block editor:

add a PaHUB with some other sensor unit assigned to it in channel 0 of the HUB, and run the script - ALL OK Physically replace the sensor (channel 0) on the HUB with the thermal unit, but assign it directly to the i2c bus, and run the script - ALL OK Add several other sensor unit to the Pa.HUB (but keep the thermal unit assigned to the i2c bus, and run the script - ALL OK (runs several times without an issue, and all sensors respond correctly)

After saving the project and relaunching UIFlow 2, the script does not run, with this message: "Thermal unit maybe not connect"

Quite confused by this.

@Kris said in AIN 4-20mA Is this correct?:

@fkarner Tak mam podłączone i odczyt wynosi ciągle zero

this works for me:

@NickMaddock Hi Nick,
sorry that i do not have a direct answer to your question. I have a question about the Roller Unit and did not get any response from the M5 Team yet. But it should be easy to answer for your: Is the Position resolution in Position mode restricked to the encoders incremental resolution or interpolated to a finer level? I'm interested in the product but would like to use is for some kind of gimbal application (mirror steering). Therefore the resolution of the encoder might be too coarse. The datasheet of the sensor states 12bit for incremental output but 15 bit using the serial interface. Unfortunately the videos from the roller unit seem to show 12bit resolution.

The question is: what is the minimal achievable setting resolution in position mode?

@ChrisFSB Any ideas here folks? Thx!

@Arn_8
Problem fixed !
Thanks !

@Elliptic3612 @matthewchan @SB12345 @sqbaczek
We have fixed this problem, please wait for the next version of UiFlow2 firmware
