I've been crafting a web interface to update an ESP32 using BLE. Check out the tutorial!
There are tons of examples out there that show you how to update your ESP32 Over-the-Air (OTA) using WiFi and transferring a binary file through your router, but what if you aren't near a WiFi router, or simply just don't want to use WiFi on the ESP32 and still want to update your software wirelessly?
This is where this webapp comes in handy. Not only is the app able to flash a binary to your ESP32, but it's also able to tell if you have the most current software, and also what the most current software is that's available for your device based on its hardware version. This app takes much of the guesswork away from an end-user who may be utilizing the easy to use, OTA update. Check out the tutorial below!
