# ESP-IDF iBeacon demo
|
||||
|
||||
From welcoming people as they arrive at a sporting event to providing information about a nearby museum exhibit, iBeacon opens a new world of possibilities for location awareness, and countless opportunities for interactivity between iOS devices and iBeacon hardware.
|
||||
|
||||
## Using Example
|
||||
|
||||
iBeacon is a trademark of Apple Inc.
|
||||
|
||||
Before building devices which use iBeacon technology, visit https://developer.apple.com/ibeacon/ to obtain a license.
|
||||
|
||||
### iBeacon Mode
|
||||
|
||||
This example demonstrates iBeacon-compatible BLE advertising, and scanning of iBeacons:
|
||||
|
||||
- **IBEACON_SENDER**: demo to send iBeacon-compatible advertising data.
|
||||
|
||||
- **IBEACON_RECEIVER**: demo to receive and resolve iBeacon advertising data.
|
||||
|
||||
Which demo will be run depends on the menuconfig, developers can set it in `iBeacon Example Configuration`.
|
||||
|
||||
The default mode is iBeacon Sender.
|
||||
|
||||
### Menuconfig
|
||||
Before compiling the demo,developers also need to configure the project:
|
||||
|
||||
```c
|
||||
idf.py menuconfig
|
||||
```
|
||||
And then enter `Component config->Bluetooth->Bluedroid Enable`
|
||||
|
||||
Because the number of peripherals may be very large, developers can enable the **BLE Scan Duplicate Options**, the maximum number of devices in scan duplicate filter depends on the free heap size, when the cache is full, it is cleared.
|
||||
|
||||
### Event Processing
|
||||
In the iBeacon receiver demo, the scan result will be posted to `ESP_GAP_SEARCH_INQ_RES_EVT` event:
|
||||
|
||||
```c
|
||||
switch (scan_result->scan_rst.search_evt) {
|
||||
case ESP_GAP_SEARCH_INQ_RES_EVT:
|
||||
/* Search for BLE iBeacon Packet */
|
||||
......
|
||||
break;
|
||||
default:
|
||||
break;
|
||||
}
|
||||
|
||||
```
|
||||
### Build and Flash
|
||||
|
||||
Build each project and flash it to the board, then run monitor tool to view serial output:
|
||||
|
||||
```
|
||||
idp.py -p PORT flash monitor
|
||||
```
|
||||
|
||||
(To exit the serial monitor, type ``Ctrl-]``.)
|
||||
|
||||
See the Getting Started Guide for full steps to configure and use ESP-IDF to build projects.
|
||||
|
||||
## Example Output
|
||||
|
||||
The iBeacon sender will broadcast iBeacon packet after initializing the Bluetooth protocol stack, and the iBeacon receiver will scan the iBeacon packet.
|
||||

||||
