Due to its broadcast nature, pairing is not required between the beacon and receiving devices. Each beacon contains a unique identifier, detectable by nearby devices equipped with Bluetooth technology, such as ESP32 and smartphones supporting BLE scanning.<\/p>\n<p>This Bluetooth beacon has a built-in 11-bit ADC, Fermion version, and multiple I\/Os that can be multiplexed to SDA\/SCL while broadcasting over Bluetooth. Users can access sensor data within broadcast range on a Bluetooth-equipped device such as a Smartphone or ESP32. This BLE beacon has a built-in 11-bit ADC and an I2C interface, allowing it to real-time collect and broadcast data from various types of sensors, including analog, digital, and I2C sensors.<\/p>\n<p><strong>DL2402Mk03<\/strong><\/p>\n<p>1 x DFRobot FireBeetle 2 ESP32-E<br \/>\n1 x Fermion: BLE Sensor Beacon<br \/>\n1 x Gravity: Analog Ambient Light Sensor<br \/>\n1 x CR2032 Coin Cell Battery<br \/>\n1 x 1 x Lithium Ion Battery &#8211; 1000mAh<br \/>\n1 x Rocker Switch &#8211; SPST<br \/>\n1 x Resistor 10K Ohm<br \/>\n1 x SparkFun Serial Basic Breakout &#8211; CH340G<br \/>\n1 x SparkFun Cerberus USB Cable<br \/>\n1 x USB 3.1 Cable A to C<\/p>\n<p><strong>DFRobot FireBeetle 2 ESP32-E<\/strong><\/p>\n<p>LED &#8211; 2<br \/>\nRSW &#8211; 17<br \/>\nVIN &#8211; +3.3V<br \/>\nGND &#8211; GND<\/p>\n<p>&#8212;&#8212;<\/p>\n<p><strong>DL2402Mk03p.ino<\/strong><\/p>\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"arduino\" data-enlighter-title=\"\">\r\n\/****** Don Luc Electronics \u00a9 ******\r\nSoftware Version Information\r\nProject #29 - DFRobot -  - Mk03\r\n29-03\r\nDL2402Mk03p.ino\r\n1 x DFRobot FireBeetle 2 ESP32-E\r\n1 x Fermion: BLE Sensor Beacon\r\n1 x Gravity: Analog Ambient Light Sensor\r\n1 x CR2032 Coin Cell Battery\r\n1 x 1 x Lithium Ion Battery - 1000mAh\r\n1 x Rocker Switch - SPST\r\n1 x Resistor 10K Ohm\r\n1 x SparkFun Serial Basic Breakout - CH340G\r\n1 x SparkFun Cerberus USB Cable\r\n1 x USB 3.1 Cable A to C\r\n*\/\r\n\r\n\/\/ Include the Library Code\r\n\/\/ Bluetooth LE keyboard\r\n#include &lt;BleKeyboard.h&gt;\r\n\/\/ Arduino\r\n#include &lt;Arduino.h&gt;\r\n\/\/ BLE Device\r\n#include &lt;BLEDevice.h&gt;\r\n\/\/ BLE Utils\r\n#include &lt;BLEUtils.h&gt;\r\n\/\/ BLEScan\r\n#include &lt;BLEScan.h&gt;\r\n\/\/ BLE Advertised Device\r\n#include &lt;BLEAdvertisedDevice.h&gt;\r\n\/\/ BLE Eddystone URL\r\n#include &lt;BLEEddystoneURL.h&gt;\r\n\/\/ BLE Eddystone TLM\r\n#include &lt;BLEEddystoneTLM.h&gt;\r\n\/\/ BLE Beacon\r\n#include &lt;BLEBeacon.h&gt;\r\n\r\n\/\/ ENDIAN_CHANGE\r\n#define ENDIAN_CHANGE_U16(x) ((((x)&amp;0xFF00) &gt;&gt; 8) + (((x)&amp;0xFF) &lt;&lt; 8))\r\n\r\n\/\/ Bluetooth LE Keyboard\r\nBleKeyboard bleKeyboard;\r\nString sKeyboard = &quot;&quot;;\r\n\/\/ Send Size\r\nbyte sendSize = 0;\r\n\r\n\/\/ Gravity: Analog Ambient Light Sensor\r\nfloat Sensor_Data;\r\n\/\/ In seconds\r\nint scanTime = 5;\r\n\/\/ BLE Scan\r\nBLEScan *pBLEScan;\r\n\r\n\/\/ My Advertised Device Callbacks\r\nclass MyAdvertisedDeviceCallbacks : public BLEAdvertisedDeviceCallbacks\r\n{\r\n\r\n    \/\/ onResult\r\n    void onResult(BLEAdvertisedDevice advertisedDevice)\r\n    {\r\n      \/\/ Advertised Device\r\n      if (advertisedDevice.haveName())\r\n      {\r\n        \/\/ Name: Fermion: Sensor Beacon\r\n        if(String(advertisedDevice.getName().c_str()) == &quot;Fermion: Sensor Beacon&quot;){\r\n          \r\n          \/\/ strManufacturerData\r\n          std::string strManufacturerData = advertisedDevice.getManufacturerData();\r\n          uint8_t cManufacturerData[100];\r\n          strManufacturerData.copy((char *)cManufacturerData, strManufacturerData.length(), 0);\r\n          \r\n          \/\/ strManufacturerData.length\r\n          for (int i = 0; i &lt; strManufacturerData.length(); i++)\r\n          {\r\n\r\n             \/\/ cManufacturerData[i]\r\n             cManufacturerData[i];\r\n             \r\n          }\r\n\r\n          \/\/ Sensor_Data\r\n          Sensor_Data = int(cManufacturerData[2]&lt;&lt;8 | cManufacturerData[3]);\r\n   \r\n        }        \r\n      }\r\n    }\r\n};\r\n\r\n\/\/ The number of the Rocker Switch pin\r\nint iSwitch = 17;\r\n\/\/ Variable for reading the button status\r\nint SwitchState = 0;\r\n\r\n\/\/ Define LED\r\nint iLED = 2;\r\n\r\n\/\/ Software Version Information\r\nString sver = &quot;29-03&quot;;\r\n\r\nvoid loop() {\r\n\r\n  \/\/ ScanResults\r\n  isBLEScanResults();\r\n\r\n  \/\/ Gravity: Analog Ambient Light Sensor\r\n  isAmbientLight();\r\n\r\n  \/\/ Read the state of the Switch value:\r\n  SwitchState = digitalRead(iSwitch);\r\n\r\n  \/\/ Check if the button is pressed.
