+
+OVERVIEW:
+This tool allows you to update your ATA Boothifier device firmware and configuration files over Bluetooth Low Energy (BLE) and WiFi. You can choose to update files only, firmware only, or both.
+
+GETTING STARTED:
+
+1. SET DEVICE/BOARD IN UPGRADE MODE
+   • hold button 1 and click the RST button on the board. 
+     - If device is in upgrade mode buzzer will beep every 5 secs.
+     - LED1 (L1) will be solid.
+     - RGB LEDS will be set to solid red.
+
+2. CONNECT TO DEVICE
+   • Make sure your device is powered on and in upgrade mode
+   • Click "Connect" button to scan for and connect to your device
+   • The device name should appear as "ATALIGHTS" by default
+   • Wait for BLE Status to show "Connected"
+
+3. CHECK STATUS
+   • When connected it will update status automatically:
+     - WiFi connection status
+     - Internet connectivity status  
+     - Current firmware version
+
+4. CONNECT TO WIFI (if needed)
+   • If WiFi is not connected, go to "WiFi Settings" tab
+   • Enter your WiFi network name (SSID) and password
+   • Click "Connect to WiFi"
+   • Return to "Upgrade" tab once connected
+
+5. CHECK FOR UPDATES
+   • Click "Check Version" to see if new firmware is available
+   • This requires internet connection through WiFi
+   • New version will be displayed if available
+
+6. CHOOSE UPDATE MODE
+   • Update Both: Updates files and firmware (requires restart)
+   • Files Only: Updates configuration/web files only (no restart)
+   • Firmware Only: Updates firmware only (requires restart)
+
+7. START UPDATE
+   • Click "Start Update" to begin the update process
+   • Monitor progress in the log area
+   • DO NOT disconnect or power off during update
+   • Device will restart automatically if firmware was updated
+
+
+TROUBLESHOOTING:
+
+• BLE Connection Issues:
+  - Ensure device is in upgrade mode
+  - Try refreshing the page and reconnecting
+  - Make sure no other devices are connected to the ATA device
+
+• WiFi Connection Issues:
+  - Double-check SSID and password
+  - Ensure WiFi network is available and has internet access
+  - Some networks may block the device
+
+• Update Issues:
+  - Ensure stable internet connection
+  - Try "Files Only" update if firmware update fails
+  - Check log messages for specific error details
+
+IMPORTANT NOTES:
+• Always ensure stable power during firmware updates
+• Device will restart after firmware updates
+• Files-only updates do not require restart
+• Log area shows detailed progress and error information
+• You can copy text from the log area for troubleshooting</textarea>
