Steps for Using Consentium IoT's OTA Service

Create an OTA-Capable Sketch: Write an Arduino sketch for your ESP32, ESP8266, or Raspberry Pi Pico W that includes OTA functionality.
Set Firmware Version: Ensure the FIRMWARE_VERSION variable is set to "0.0". This indicates the initial firmware version. You can update this to any version number as needed, but 0.0 is used here for demonstration.
Connect the Board: Connect your IoT board to your development machine using a USB cable.
Upload the Sketch: Upload the OTA-capable sketch to the board using the Arduino IDE.
Log In: Log into the Consentium IoT Cloud.
Navigate to Device OTA: Go to the Device OTA page. You should see the OTA-capable device listed with its current firmware version displayed.
Disconnect the Board: Ensure the IoT board is no longer physically connected to the development machine.
Update the Sketch: Make any desired changes to your code and update the FIRMWARE_VERSION variable to "0.1" (or any new version number).
Export the Compiled Binary: In the Arduino IDE, go to the Sketch menu and click on Export Compiled Binary. This action generates a .bin file for the updated firmware, which will be saved in a folder under your project directory.
Upload the .bin File: Return to the Device OTA page in the Consentium IoT Cloud.
Select and Upload: Choose the generated .bin file and upload it to the appropriate board.
Check Firmware Versions: After the update is pushed, verify that the Current and Board Firmware Versions are the same to confirm the update was successful.
