(Under the "Usage Examples" menu at the top) Review: As described and mentioned. - Excellent product, install KBeacon app and you have the option to change the configure, much more options to configure than tile. Review: Great for home automation presence detection - I use these with ESPresense and Home Assistant in my home and business. In my business it turns lets the building know when one of my employees is there. Then Homeassistant turns on the lights and adjusts the thermostat. When everyone shows as gone homeassistant turns off any remaining lights and outlets ensuring no coffee pots, etc are left on over night. That functionality would not be possible without these little devices on my key employee's key chains. ## Features - Compact Beacon with Button Trigger: This compact beacon includes all of the usual beacon features as well as a button trigger option that can be configured to trigger different broadcasts or broadcast only for X seconds after being pressed or broadcast a different UUID after pressed. - Long Range BLE 5.0 Compatibility: Features Long Range BLE 5.0 technology while maintaining full compatibility with BLE 4.0 phones and scanners, ensuring broad device support across different Bluetooth versions - Battery Level Monitoring: Shows battery level directly in TLM broadcast transmission, allowing you to monitor power status without needing to physically check the device - Multi-Format Broadcasting: This Multi-Beacon broadcasts your choice of iBeacon, Eddystone TLM, Eddystone URL, and/or Eddystone UID format with Eddystone TLM broadcasting battery strength, temperature, and count data. - Fully Customizable Settings: Beacon name, UUID, TX broadcast strength, broadcast interval, major/minor values are all customizable via free apps with wide TX Power range from -40 to +4dBm and adjustable intervals from 100 to 10,000 milliseconds - Extended Transmission Range: Transmit distance ranges from 0.2 to 90 meters, providing flexible coverage options to tailor to your specific project needs and environment requirements - Complete Package with Long Battery Life: Includes CR2032 battery with up to 16 months battery life at 1 second interval and 0dBm in unconnectable mode, plus 3M double-back tape for easy surface mounting ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B085XN9B7N | | Brand | Blue Charm Beacons | | Color | Black | | Colour | Black | | Compatible Devices | Smartphones, Tablets, Other BLE-enabled devices (such as ESP and ESPResence) | | Compatible devices | Smartphones, Tablets, Other BLE-enabled devices (such as ESP and ESPResence) | | Customer Reviews | 4.2 out of 5 stars 89 Reviews | | Finish | Blue | | Finish type | Blue | | Input Voltage | 3 Volts | | Item Dimensions | 36 x 36 x 6 millimeters | | Item Type Name | iBeacon | | Item Weight | 8.6 Grams | | Item dimensions L x W x H | 36 x 36 x 6 millimeters | | Manufacturer | Blue Charm Beacons | | Mfr Part Number | BC-011 | | Model Number | BC011 | | Number of Items | 1 | | Number of Ports | 1 | | Package Quantity | 1 | | Power Plug Type | No Plug | | Smart Home Compatibility | Smart Home Compatible | | Specific Uses For Product | asset tracking, home automation | | Specific uses for product | asset tracking, home automation | | UPC | 600155202726 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Blue Charm Beacons - **Colour:** Black - **Compatible devices:** Smartphones, Tablets, Other BLE-enabled devices (such as ESP and ESPResence) - **Item dimensions L x W x H:** 36 x 36 x 5 millimeters - **Specific uses for product:** asset tracking, home automation ## Images ![Blue Charm Beacons - Bluetooth BLE iBeacon (BC011-MultiBeacon) - Shows Battery Level in Broadcast - Long Range BLE 5.0 - Image 1](https://m.media-amazon.com/images/I/61T+-E0LvfL.jpg) ## Questions & Answers **Q: can i make this beacon connectable with my android phone so I can use it as the smart lock trusted device feature on my phone?** A: As far as I know, no, you can’t use a beacon as a smart lock trusted device. Why not? Because smart lock works with a connection to a Bluetooth device, e.g. a device such as headphones. When the device is present AND connected to your phone, your phone will stay unlocked. Beacons, on the other hand, do not connect to your phone ever, unless you are configuring them (which you usually will only do once in the lifetime of the beacon). One idea: I can’t guarantee it, but I think one of those “lost keys/luggage” devices would work. I’m definitely not sure about this though, so do some more research first. **Q: Can you use it to send a url?** A: Yes, but you should note that beacons can not cause messages to appear on nearby phones unless those phones have your app installed. Without an app, beacons broadcasting URLs will have no effect on nearby phones. If you are reading articles that say this is possible, those articles are two years out of date. **Q: Could these be set up to track employees leaving and entering the building in lieu of clocking in?** A: Sure, that's one of the most common uses for beacons. Quite a few medical facilities are adding this feature to keep track of doctors, nurses, PAs, etc. and how much time they spend in each treatment room, etc. In this scenario, the employee would carry the beacon with them. The main challenge will be for you to set up a scanner to scan for known beacons and to log the time that they enter and then later exit. This type of hardware is called a gateway, e.g. BLE gateway. Gateways are not cheap and require some tech skills to set up, but it's all doable if you invest some time in learning the basics. Another much cheaper option is to make a DIY gateway using a programmable module such as a ESP32 or similar. You can contact me anytime on the Blue Charm website if you would like more info about this topic. **Q: Can you recommend a usb ble 5.0 dongle to reading these beacons?** A: Wish I had a good answer for this one, but I have not spent any time working with BLE dongles yet. One thing to be careful of: There are many many Bluetooth dongles on Amazon, but nearly all of them are for connecting a bluetooth keyboard to your computer (or headphones to your computer or similar type of application). These will NOT read beacons. What you need is a BLE dongle specifically for reading/scanning beacons. ## Customer Reviews ### ⭐⭐⭐⭐⭐ As described and mentioned. *by M***. on 11 March 2022* Excellent product, install KBeacon app and you have the option to change the configure, much more options to configure than tile. ### ⭐⭐⭐⭐⭐ Great for home automation presence detection *by H***X on 20 October 2024* I use these with ESPresense and Home Assistant in my home and business.

They take a few seconds to update but their ease of setup and configuration options, ability to lock down and replaceable battery means I’ll be using these for quiet some time. ## Frequently Bought Together - Blue Charm Beacons - Bluetooth BLE iBeacon (BC011-MultiBeacon) - Shows Battery Level in Broadcast - Long Range BLE 5.0 - Blue Charm Beacons - Bluetooth BLE iBeacon (BC021-MultiBeacon) with Movement Sensor - Long Range BLE 5.0 - Blue Charm Beacons - Long Range Phy (300m) Water-Resistant BLE iBeacon (BC04P-MultiBeacon) - w/Adjustable Movement Sensor --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.sg/products/388769618-blue-charm-beacons-bluetooth-ble-ibeacon-bc011-multibeacon-shows-battery](https://www.desertcart.sg/products/388769618-blue-charm-beacons-bluetooth-ble-ibeacon-bc011-multibeacon-shows-battery) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-07-06*
