## Description

Full description not available

## Features

- Our newest USB-powered beacon makes battery life a non-issue. In addition, because there is no battery to worry about, you can speed up the broadcast interval to 100ms to make it easier for phone/scanner to "see" and react to the broadcast very quickly. Does not include wall charger; compatible with any standard USB-A 5V wall charger or USB-A port on a computer or inside a vehicle. IMPORTANT NOTE: This item is NOT a USB dongle for connecting a bluetooth keyboard or speakers or other device to your computer. Please do NOT order this product unless you are actually looking for an iBeacon or Eddystone Beacon.
- Broadcasts your choice of iBeacon, Eddystone TLM, Eddystone URL, and/or Eddystone UID format. Eddystone TLM can broadcast battery strength, temperature, and broadcast count data.
- Free configuration apps for iPhone & Android allow you to adjust settings according to your needs.
- Transmit distance: 0.2-60 meters when using BLE 5.0. Selectable TX levels: -40, -20, -16, -12, -8, -4, 0, +4dBm
- Our website has very detailed step-by-step instructions with multiple screenshots under the Quick Start Guide menu.
- This beacon is compatible with all bluetooth-capable smartphones as well as with our BLE beacon scanning gateway (Item BCG04). Works great with Home Assistant too. See our website for some sample projects using beacons with HA. (Under the "Usage Cases" menu at the top)

## Questions & Answers

**Q: Hi. Is this product has an sdk for software developments?**
A: This beacon broadcasts the standard iBeacon protocol, as well as two standard Eddystone formats (UID and URL). To build an app to work with beacons, all you need to use are the standard beacon libraries for Android and IPhone. No special SDK is needed. If you are interested in developing an app for configuring this beacon (we already offer a free app for that), you can contact us directly via our website for SDK links.

**Q: Can this act as a trigger in HomeKit to automate things?**
A: Yes, iBeacons can trigger automations but not directly using the Home app on iPhones. You need to use some other third-party app for this. 

One that I know of is called PushCut for iPhone. As with most of these third party apps, it still requires you to tap the screen to confirm the automation before it runs, e.g. "You have triggered an automation. Tap here to let it run"...something like that. Which takes away most of the fun of an automation. 

But PushCut also allows you to set up a spare iPhone or iPad or iMac to act as a "server" for your automations. That's just a fancy way of saying they use this server method to get around Apple's "user confirmation" requirement, so then your automations can run without any needed confirmation from you. 

I previously set up as a test automation so that when I walked into my office (which had a Blue Charm BC-U1 beacon installed and broadcasting), my phone would connect to the bluetooth speakers in the office and begin to play music from my selected playlist. When I left the office, it would turn off the music. It worked great, but you should double check with the documentation of PushCut to confirm this is still possible. Sometimes Apple adds "security restrictions", and apps like PushCut will lose some functionality for a while. 

There are quite a few other apps that can also do something similar, but I have not tested them all. You can find them by searching for "iBeacon automation" in the Apple App Store.

### ⭐⭐⭐⭐⭐ Works very well
*by T***  on March 23, 2025*

I bought this to maximize a fancy navigation app. It works very well.

### ⭐⭐⭐⭐⭐ Perfect
*by A***M on November 16, 2024*

Bought to use as beacon for PhotoSync app on iPhone because geofencing unreliable, specifically if phone is connected to CarPlay when you approach the target zone.Now photos sync perfectly when arriving at home.Also, moving around the home, if I take photos and I’m out of range, once I’m back in range it will sync.Have it hooked up to home server, which then backs up to Dropbox.No need to pay for iCloud as well.

### ⭐⭐⭐⭐⭐ Ease of use windows C#
*by K***S on December 8, 2024*

I was able to quickly configure this iBeacon using iphone then created a BLE Advertisement listener to determine proximity using the Windows UWP Bluetooth example. Fun little toy.
