  @jeffb no, no, no don't edit the files! There are 2 causes for the error that has plagued M5Stack since the beginning. 1st - driver issue. the driver is temperamental in osx and often does not work. 2nd and most important as its the biggest issue. The factory USB leads are often faulty and or just rubbish. Always use a high quality USB sync/data lead. something over the £10/$10 price range and never fold the lead, always roll it. I had this issue when I first started as I have only OSX. Also, when you install any new board or library in arduino, ALWAYS close arduino and restart it!

  @BricoMS Thank you for the answer. I thought, that the hardware/controller of M5Stick and M5Stack are the same and that MicroPhyton is just another way of displaying the blocks of UIflow. I do not understand why M5Stack made no "fair" advertisement/documentation. For me it would be "fair" if they would write "ESP32-based support BLE 4.2 and WiFi not compatible with UIFlow"" I think, for some (many ?) users the UIFlow possibility is an argument for M5Stack/Stick. regards K.D.

  @capatinshimapan When you switch on the StickC after burning the firmware you need to immediatly press the "A" button to access the setting menu. In the setting press button a to go into mode and be to move to usb mode and press a to select usb mode. Press the reset button and it should boot into usb mode.

  Thanks. I was hoping I'd missed some way to do this in UIFlow, as it is fun to knock up some code that way. But ... back to C for me.

  Hello @DG4EK I've just tried the current Factory Test firmware from github on my M5StickC and it works just fine for me. Re file size too large: Arduino IDE: choose partition scheme: No OTA (Large APP) PlatformIO: add board_build.partitions = no_ota.csv to platformio.ini Hope this helps. Cheers Felix

  so - I installed that driver -- and it works ! (on all of my PCs and notebook) Perfect !! I found that I have to burn the M5Flow UI 2 times. The first time the burn process was very fast (about 5s) and after that the device shows no reaction - screen black - no reaction on any key. (according to the PC display everything was ok - no error) The second time burning was about 5 times slower, but now every thing is as it should be. The M5Stick works and I can use UIFlow. Strange -- maybe sometime anybody can explain ........ @sudoku: Thanks again for your help. regards K.D.

  Hello @juanpablo unfortunately the current version (as of today) of the official M5StickC Plus library is still broken in regard of light sleep or deep sleep. The faulty function is SetSleep() which powers M5StickC Plus completely off (as you encountered) and therefore the system cannot wake from light sleep or deep sleep. This is also the reason you have to press a button to power the system back on again to allow for a new download. So yes, the problem is related to the official library. At this point I would not count on the issue being officially resolved anytime soon - the issue has been raised a couple of months ago, the solution is simple, but the M5Stack engineers seem to be busy with new stuff rather than fixing bugs for older hardware. That said, fortunately the issue can be fixed easily. I suggest you follow the advise in the issue you mentioned and fix the SetSleep() function in your local copy of the M5StackC Plus library yourself. Good luck! Felix

  Hello @ozehnder looking at the factory test source code, error 0x21 appears when the AXP192 temperature reading either is below 5 or above 90 - which is used as an indicator that communication with AXP192 cannot be established. I probably would try to run the AXP192 example to see if the AXP192 really refuses to communicate and if yes contact the store for a replacement. Thanks Felix

  Hello @helo-head could you share your code (or at least the WiFi relevant part)? Anyhow, below is how I can successfully connect my M5StickC Plus to WiFi: #include "M5StickCPlus.h" #include <WiFi.h> const char* ssid = "ssid"; const char* password = "password"; void setup() { M5.begin(true, true, true); Serial.printf("Connecting to %s ", ssid); WiFi.begin(ssid, password); while (WiFi.status() != WL_CONNECTED) { delay(500); Serial.print("."); } Serial.println(" CONNECTED"); } void loop() { } Thanks Felix
