DX-Smart CP28
Bluetooth Station 2024 Model A (BS24a) is a battery powered mesh station that can operate between 3 to 5 years without needing a change of batteries.
BS24a is based on the DX-Smart CP28 that ships with a double-sided sticker and 2 batteries already installed inside.
1. Applications
BS24a is a game changer in terms of Activity Marker roll-out, enabling ultra low-cost and low-fast deployed in almost any location:
- Advertising Billboards
- Public Transports
- Lifts and Basements
- Caves and Tunnels
Use your imagination to grow your Compute Asset - see where you can stick one of these BS24a to and earn some Compute Income!
FREE BS24a Offer
We are providing up to 100 BS24a for FREE to Compute Owners in each country for deployment in spaces where deploying WS24a is not feasible or too difficult. Make post under the Citizen StartUp Forum with topic name "Free BS24a" to apply.
2. Features
BS24a has many advantages as a Radio Activity Marker:
- It is small and compact
- It does not require external power
- Its batteries do not need recharging or changing for 3 to 5 years
- It can be programmed manually without touch over Bluetooth using an iOS application
- It can be deployed high up or in hard to reach places to prevent vandalism
Some BS24a disadvantages include:
- It can only broadcast Radio Activity Markers, it cannot scan for other radio signals
- The Activity Markers it broadcasts cannot change very often.
Since programming a new Activity Marker into the BS24a is a manual process, it is used mainly in applications where the Activity Marker value does NOT need to be changed frequently.
If a power source is available, you should deploy the WiFi Station 2024 Model A (WS24a) instead, which enables the Activity Marker at anytime using via WiFi.

Note Android is not as reliable with Bluetooth Beacons as iOS, we recommended using the iOS app (not the Android app) for programming.
