Esp32 ibeacon scanner. May 20, 2025 · We will specifically delve into Apple’s popular iBeacon format, learning how to make your ESP32 act as an iBeacon transmitter and how to build an ESP32-based scanner to detect and interpret iBeacon signals. Micro USB Cable Software: 1. I installed the ESP32 board in the Arduino IDE. Contribute to espressif/arduino-esp32 development by creating an account on GitHub. Instructions on how to integrate iBeacon devices into Home Assistant. Arduino IDE 2. Hardware: 1. The esp32_ble_beacon component creates a Bluetooth Low Energy Beacon with your ESP32 device. In the sections below, we will walk through this code together step by step. I loaded the sketch BLE_scan from the ESP32 BLE Arduino examples . ESP32 is a small single board computer that can easily be programmed to do different tasks. … Now I'm porting all the code i have from esp8266 to esp 32, the device will be commercial device and i have one question, how to scan for ibeacons using esp32 BT function to get the list of iBeacons with their rssi to calculate the nearest one ? Is there any sample on hint how to use bt function od esp32 as iBeacon canner ? A BLE scanner application for ESP32 that publishes all detected BLE devices using MQTT. . This BLE scanner app provides good Graphical Interface (GUI) but lacks in add Sep 9, 2025 · Learn how to build an ESP32 BLE beacon scanner for reliable room-level presence detection in Home Assistant using ESPHome. About BLE Beacon (iBeacon protocol) Scanner for ESP32 - 'esp-idf '--- Based in 'esp-idf' example ESP32 Compatibility: Utilizes the ESP32 development board, offering robust hardware support and capabilities. Beacons are BLE devices that repeatedly just send out a pre-defined packet of data. Arduino core for the ESP32. Perfect for smart home automations. min_rssi (Optional, int): at which minimum RSSI level would the component report the device be Learn how to set up and use BLE beacons with this comprehensive Bluetooth Low Energy tutorial. Nov 4, 2025 · Anyways, beaconDB is a really interesting project for crowd sourcing cell tower, BLE Beacon and WiFi access point observations. I've been contributing observations using the Neostumbler app, but there is a noticeable battery impact. ibeacon_minor (Optional, int): The iBeacon minor identifier of the beacon that needs to be tracked. There were similar topic, but I was never able to find a solution. Many ESP32 boards include Bluetooth so it’s possible to program them to be an iBeacon. The article first explains how to detect beacons on Android using nRF About ESP32 code to advertise as BLE iBeacon, or scan for iBeacon advertisements and reports them using MQTT. - nkolban/ESP32_BLE_Arduino A BLE scanner application for ESP32 that publishes all detected BLE devices using MQTT. Setup: Home Assistant Several ESP32 with ethernet port (and some WiFi-connected just to test) flashed with ESPHome with BLE proxy mode A few Android phones with HA companion app set up to broadcast iBeacon messages iBeacon integration in HA Outcome: HA sees a lot of BLE devices (smart watches etc) fine and stable HA does not Usually used to group beacons, for example for grouping all beacons in the same building. The ultimate goal of the project is server-side indoor positioning using multiple ESP32 devices that detect beacons. Android App: nRF Connect for Mobile (By Nordic Semiconductor) There are many BLE scanner apps, one of them we have used in our previous project of How to Use HM-10 BLE Module with Arduino. Usually used to identify beacons within an iBeacon group. iBeacon Protocol: Implements the iBeacon protocol, facilitating seamless integration with various BLE-enabled devices and applications. Used for research in COVID-19 contact tracing. Discover hardware options, configuration steps, applications, and troubleshooting tips for beginners and pros. ESP32 Development Board 2. The library source for the ESP32 BLE support for Arduino. The hydrometer is perfectly detected: Address F7:44:3E:01:7F:36 ManufacturerData 4C 00 02 15 A4 95 BB 20 C5 B1 4B 44 B5 12 13 70 F0 2D 74 DE 00 4A 03 F1 22 4C 00 :Apple beacon 02 :type ( constant ,defined by ibeacon spec ) So I got an ESP32 working to detect an iBeacon transmitting from an android phone but when I turn off the beacon the LED won't turn off and I can't find the reason it is not doing it since I got the delays properly set. The following is the entire example sketch of how to create and use a BLE Beacon Scanner with your ESP32. Making an iBeacon Using ESP32 Circuit Digest has a new tutorial ESP32 based Bluetooth iBeacon. c3grhg, psyfs, 701x, vu1xm, vlwfn, tqjd1z, te5dad, f8yfe, cmlh, ltng7,
