## Description

desertcart.com: Blue Charm Beacons - Bluetooth BLE iBeacon (BC011-MultiBeacon) - Shows Battery Level in Broadcast - Long Range BLE 5.0 : Electronics

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.
Review: Really good for home automation - Using these with room assistant to track everything from water bottles to my AirPods. 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.

## Features

- This compact beacon includes all of the usual beacon features as well as a button trigger option. Long Range BLE 5.0 but also compatible with BLE 4.0. Shows battery level in broadcast. Button can be configured to trigger different broadcast. The button can even be configured so that the beacon only broadcasts for X seconds after being pressed or broadcasts a different UUID after pressed.
- Broadcasts your choice of iBeacon, Eddystone TLM, Eddystone URL, and/or Eddystone UID format. Eddystone TLM broadcasts battery strength, temperature, and broadcast count data every tenth broadcast. (This is NOT an Eddystone URL beacon for broadcasting your website or ad message to nearby phones. That service has been SHUTDOWN WORLDWIDE by Google as of Dec 6, 2018.)
- Free configuration apps for iPhone & Android allow you to adjust settings according to your needs.
- Transmit distance: 0.2-90 meters. 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 Examples" menu at the top)
- (This is NOT an Eddystone URL beacon for broadcasting your website or ad message to nearby Android phones. Due to abuse by spammers, that service was SHUTDOWN WORLDWIDE by Google on Dec 6, 2018.

## 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.

### ⭐⭐⭐⭐⭐ Worked right out of the box, easy to configure!
*by I***D on May 18, 2020*

I bought this beacon after consulting with the BlueCharm Beacon support folks (they responded within a couple of hours of my request) because I wanted to experiment with scanning for beacons from an iOS app using CoreBluetooth as opposed to the Beacon APIs in CoreLocation. Since iBeacons aren't normally detectable using CoreBluetooth, I needed a beacon that could advertise in other formats, such as Eddystone. I was able to successfully scan for Eddystone UID and TLM payloads (I'll provide BlueCharm with the details so you can likely ask them directly about this if you are interested). The suggested KBeacon iOS app worked flawlessly for configuring the beacon. I was able to use it to change the UID/TLM payloads and then see those custom values in the advertising data when scanning with CoreBluetooth! Throughout this, BlueCharm support was very helpful and responsive to all of my questions. Thanks again!
