  Hello had the same problem. Solution with me, Use an older 5V USB power supply. The new ones switch off due to insufficient power consumption. Motorola review 2020 low A. = off Samsung v. 2015 no problem. Try old power supplies without high-performance charge control. 73/ Klaus

  Hello @anichang just wondering - maybe the issue isn't specific to PSRAM but with the power supply? I'd try a different power supply and/or shorter USB cable. Thanks Felix

  1st thing to do is DON'T Panic! Next remove the base and module leaving only the firecore. Plug a usb cable in and connect just the core section into a computer, go into hardware reports and check usb devices. Do you have a USB to UART adapter? Try the instructions on this page to use an external adapter https://docs.m5stack.com/#/en/tool/usb_downloader?id=esp32-downloader

  @uniko92 Firmware on the Fire is really old. Please use M5Burner to upgrade it to 1.7.4.

  @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.

  @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."
