  I have a similar problem. I powerd my M5Stack core black from a Stepmotor module and was not able to connect with the WLAN for programming. So I connected a small powerbank to the USB-C of the M5Stack. After resetting the display stayed black. Using a power adapter for the USB-C port also did not change anything. The M5Stack did not start. What I found out was that the powerbank did not deliver 5V correctly ( I measured 3.7V). May there be a conflict with the charging circuit when the Core is powerd over the Stepmotormodule (12V) and a voltage lower than 5V from the USB-Cat the same time? Some weeks ago my M5Stack grey stopped working when i tested a LEGO+ module. Now I have a black and a grey module and both displays keep dark and are not working. Any ideas?

  @sodoku Thanks a lot. That solved my problem. Seems my Core came with a very old software image. In the M5Flow Menu there's a very helpful video on how to flash. It took me 10 minutes and now I'm having fun with my core.

  Oh - interesting ! If it's for battery, then I think a 3,7 V akku will work - the same they are using in the moduls. Thank you. K.D.

  I erased the flash of the Fire core and load it new with UIFlow V1.7.2 (the same version as before) and now everything works !!?? Is was not easy - because at the beginnning there were time-out errors - the burner software can't connect. Strange - because the download and execution of skeches from UIflow worked. If powered the Fire down - wait 30min - shut down windows complete. After new start I could erase the Fire core - but here were a long time delay until the software can connect and erase - about 5s. Now I could flash UIflow - but again it seems, that the burner has to wait. The process was about doubble the time compared with my M5Stack Faces. Now the akkus in both modeles are loaded and the Fire core works with the akku power - like it should be. Strange !!! What has a firmware update to do with connecting to akku and the way of power supply for the core ?

  @adcse Just program it with WiFi or USB and then set up the BLE connection within the Blynk app (via the BLE widget). The configuration (hardware device to app) for Blynk within uiFlow is only BLE (i.e. no option for WiFi), so it's not relevant for the actual programming of your M5Stack Fire via WiFi or USB.

  Hello @sysLINK I understand you've installed UIFlow 1.7.1-fire firmware on your M5Stack Fire, correct? I do not have the LoRA868 module myself so my conclusion could be wrong. But looking at the spec sheet of the LoRA868 module I don't see UIFlow mentioned, so I don't think this module has UIFlow integration. Have you tried the Arduino example? Thanks Felix

  No, ESPnow doesn't work with an access point. It behaves a bit more like Bluetooth. From https://www.espressif.com/en/products/software/esp-now/overview : "ESP-NOW is yet another protocol developed by Espressif, which enables multiple devices to communicate with one another without using Wi-Fi. The protocol is similar to the low-power 2.4GHz wireless connectivity that is often deployed in wireless mouses. So, the pairing between devices is needed prior to their communication. After the pairing is done, the connection is safe and peer-to-peer, with no handshake being required."

  Is there a deep sleep mode for Fire?

  Hello @houkensjtu ok, I see. In UI-FLOW you could use an Execute code block and add something like this for deep sleep: import machine #sleep for 10 seconds machine.deepsleep(10000) or light sleep: import machine #sleep for 10 seconds machine.lightsleep(10000) BTW: I found a nice tutorial about MicroPython and sleep modes here. Cheers Felix

  Hello @michaelblight sorry to hear. There is a fuse (labelled T200) in the M5Core Fire which might be the only thing that blew. Thanks Felix

  Thanks! My son is beta testing it now, he picked purple and yellow as the colours for the Leds =). I've added some extra's so we can set the timer manually (increments by 5) and added some extra's like a basic battery indicator. I'll post it on the Community platforms when we reach a stable, working feature.

  I did erase, and M5Burner did never complain but it didn't solve the problem I don't know why but as I tried again and again, it worked...pretty weird...

  Just calling the screenrotate function will not rotate the already drawn screen contents. Just after using this function, the rest of the graphic functions will draw on the screen in a different orientation. So it seems to me that where this instruction does not need to be right at the beginning of the program.
