how's the UiFlow version 2.0.x coming together? Any updates?

Thanks
Felix

i.e. I am trying to use UHF-RFID unit on UIFlow and most of blocks don't do anything or give errors:

• Set region code ERROR name REGIN_EU isn't defined
• Multiple polling read NOT WORKING
• Select mode NOT WORKING
• Set tx power ALWAYS RETURN 256
• Enable /disable continuous carrier NOT WORKING

And so on...

Re WiFi: I can confirm that scanning for WiFi APs works on an M5Core2 (which has PSRAM). So indeed, it seems to be a RAM issue.

Yes, thanks for you feedback, I always use CORE2 for develop and test,so I didn't notice that, we will release some new FW at this friday with more bug fixed.

Thanks for your contribution.

I’m not sure if the issue with Blynk is Blynk side or UIFLOW side.

Based on previous discussions here, there are indeed some issues that need to be identified and dealt with, which we will test and investigate as soon as possible.

no need to apologize - I hope you had a great holiday.

Re ESP32c3: thank you for the clarification. I suspected that much. The different architecture requires a different firmware.

@IAMLIUBO I have been recommending a firmware builder for a while because of the issue you had with firmware size.
Please, please, please me need a stand alone server that can be run on a raspberry pi!

This is a little lower priority, there are still some important things to deal with, we will release a preview version as soon as possible (online firmware function selection and generation).

Thanks for your recommend and help us be better.

Have a nice day.

I tried it, there is indeed a bug, devices with psram might work, try it and we'll fix it.

P.S.

Thanks for report this :)

Hi, sorry for taking so long to reply.

Trying the beta firmware on an M5Stamp C3 fails - I guess due to the risk architecture which probably requires a different bootloader. Or am I missing something?

I'm very sorry, it's my problem, I didn't say that this firmware does not support C3 chip, it currently supports ESP32, because of the different architecture, it is impossible to make a firmware support esp32, esp32-c3, esp32-s2, esp32-s3 at the same time.

Hi, sorry for taking so long to reply, just finished the Chinese New Year holiday :)

We did have some issues with our servers during the holidays, sorry about that, it should be fixed now, sorry again.

Have a nice day.

Hi, sorry for taking so long to reply and thanks for report this bug, We will investigate this issue as soon as possible.

Hi, sorry for taking so long to reply, just finished the Chinese New Year holiday :)

does this include the stamp pico and stamp C3?

I have not tested the STAMP series, but STAMP-C3 is not supported (the architecture is different and needs to be compiled separately)

Have a nice day.

Hi, sorry for taking so long to reply, just finished the Chinese New Year holiday :)

This is great news! The old MicroPython in M5Stack firmware was the last remaining obstacle holding me from removing some ugly workarounds in Thonny's MicroPython backend.
According to my quick initial test Thonny is happy with the new firmware. I tried the original gray M5Stack and Atom Lite. With the gray M5Stack even the "paste" communication mode, which for some reason did't work with M5 earlier firmwares, now seems to work without problems. With Atom Lite it still causes problems, which I'll investigate later.

Thanks, the old MicroPython firmware for M5Stack(or UIFlow firmware) there are indeed some incompatibilities with micropython (such as paste code in repl mode).

I also like the decision to use common firmware for all M5 devices and the fact that now one can use the same esptool arguments as for other ESP32 devices. This means Thonny users can use the built-in flashing dialog for M5 devices.

Yes, one firmware that works for all M5 devices would be a good choice, but this would also be a limitation since the flash chip size is different for different devices, but we can guarantee that the esptool arguments will be the same (only For ESP32, if it is S2 or C3, may need to add some additional parameters).

I'm considering adding a separate "MicroPython (M5Stack)" back-end in the upcoming Thonny 4.0, but this is warranted if it came together with M5-specific MicroPython stub files (.pyi) for autocompletion and static analysis (one of the main theme of Thonny 4.0 will be improved autocompletion).
This is where you could help me. Most likely I don't find time for compiling the stubs from the scarce documentation myself, but if you created the pyi-files describing M5-specific modules, I would include them in Thonny 4.0 under "MicroPython (M5Stack)" back-end.

Wow, this is really good news.Thank you very much, this is currently a very early preview firmware, and some API modifications and adjustments may be made later, but I am very willing to keep in touch with you, I will try to process a pyi file, is mypy tool okay?

Have a nice day.

Hi, sorry for taking so long to reply, just finished the Chinese New Year holiday :)

ulab will support, but lvgl for micropython will take a lot of flash space, we may only support some devices (such as CORE2, TOUGH, etc.), because the early basic flash chip is only 4M in size.

This needs to be discussed, maybe we will launch a service to generate firmware online, you can choose which functions or drivers are packaged into the firmware.

Have a nice day.

using Thonny and M5AtomLite running UiFlow 2.0.0 beta firmware

MicroPython b084d9e-dirty on 2022-01-28; M5STACK with ESP32

I tried to scan for WiFi networks with this code:

import network
nic = network.WLAN(network.STA_IF)
nic.active(True)
res = nic.scan()
print(res)

but I get an error:

Traceback (most recent call last):
  File "<stdin>", line 2, in <module>
RuntimeError: Wifi Unknown Error 0x0101

Edit: when I install native ESP32 MicroPython firmware 1.17, e.g.

MicroPython v1.17 on 2021-09-02; ESP32 module with ESP32

the above code works to scan WiFi networks. What am I missing?

Thanks
Felix

One firmware can be used on all M5STACK devices

Hello @m5stack

Trying the beta firmware on an M5Stamp C3 fails - I guess due to the risk architecture which probably requires a different bootloader. Or am I missing something?

When I flash to 0x1000 I get "Invalid image block, can't boot."
When I flash to 0x0000 I get "Invalid chip id. Expected 5 read 0. Bootloader for wrong chip?"

Thanks
Felix

When I move the code to the desktop version only half of it loads. many of my functions are missing. I am 2 hours before a public showing and I need this up and running please help.
