In a recent tutorial I explained how to detect the presence of an iBeacon with the esp32 chip. The iBeacon used to demonstrate the program is manufactured by a chinese Company, Wellcore, and sold by Banggood.

The transmitter is enclosed in a plastic, non waterproof, case of 4x4cm size:

The enclosure has a hole that allows you to hang the iBeacon on the wall or alternatively use it as a key ring.

The transmitter is based on a double-sided circuit board: one side hosts all the components, while on the other side you find the lithium battery that powers the iBeacon. The antenna is also printed directly on the PCB.

A switch allows you to turn the iBeacon on or off:

Unlike Bangood says, this iBeacon is based on the Nordic nRF51822 chip:

The use is very simple: just turn the iBeacon on and it continuously transmits the advertising package containing its unique UUID.

The manufacturer also offers an application to customize some parameters of the iBeacon. For iOS smartphones you can download the “Wellcore Beacon Tool” app from the App Store, while for Android the apk file of the application is available for download on this website.

The app performs a scan looking for compatible iBeacons:

Once found an iBeacon, you can change some of its parameters (in the example, its name):

The change is effective as soon as you click the Write command:
