 # ESP32-OTA-File-management
-ESP32 OTA Firmware update & File management.
+OTA Firmware update & File management for ESP32.<br>
+This sketch will let you:<br>
+1. Update ESP32 Firmware using a compiled binary file.<br>
+2. Upload SPIFFS.bin that can contain supporting files that you might need for your project.<br>
+3. Browse, Delete, and Upload files stored on ESP32 File system.<br><br>
+
+<b>Make sure</b> that your partition table is ready for OTA. You can select predefined Partition tables in Arduino IDE or create your own.
+<br><br>
+I used 16MB chip so my partition table looks like this.<br>

+
+<b>Don't forget</b> to include your local network SSID and PASSWORD.<br>
+Then when everything is up and runnig you can access main page via esp32.local/ or using ip address that will be reported into a serial monitor.<br><br>
+
+<p><b>1.</b> Firmware update is very straightforward. Bin file can be simply generated using Arduino IDE. Then find it, select it and press Update button. If successful there will be a popup window and after presssing OK you will be redirected to the main page. Meanwhile ESP will reboot and rewrite its APP derictory with uploaded bin.<br>

+<p><b>2.</b> SPIFFS.bin upload. For this one I used MKSPIFFS tool to generate SPIFFS.bin file. Command that initiates compiling looks like this:<br>
+<b>mkspiffs -c C:\Users\xxxx\Documents\Arduino\OTA_file_management\data -b 4096 -p 256 -s 0x6F0000 spiffs.bin</b><br>
+it compiles everything that is in data folder into one bin file. 0x6F0000 is the size of your SPIFFS partition and depends on partition table you choose.<br>

+<p><b>3.</b> You can browse/delete/upload files stored in SPIFFS.<br>
