1.BLE Beacon Card Introduction
DSBC-120 is a portable Bluetooth beacon card developed by Dusun IoT. Suitable for indoor positioning, asset positioning, scenic navigation, patrol check-in, advertising push, asset management, project tracking, and other scene applications.
This BLE beacon card is developed based on the NORDIC’s NRF52820 chip and has the built-in Bluetooth 5.0 and above protocol, with excellent function of ultra-low power consumption. It has a red LED light and switch.

5. BLE Beacon Card Caution
- Being close to a metal object will interfere with the signal, causing the signal to be weakened.
- Note the distance between DSBC-120 and the receiver to guarantee the accuracy of receiving.
- Keep away from corrosive objects.
6. BLE Beacon Card Reference Usage
1)BLE Beacon/sensor broadcast the data.
2)Bluetooth Gateway gets the data from the beacon and sends the information to Cloud via Wi-Fi or LTE once per second.
1) The device will always want to send a broadcast packet nearby at a certain frequency.
2) A mobile phone with Bluetooth enabled can receive the beacon information and parse the data through the APP
7. BLE Beacon Card Development
The mobile phone can read and parse beacon data and set parameters through APP
|Broadcast Packets Read||●MAC address |
|●MAC address |
●User service data
|●MAC address |
● Sensor data
|Set Parameter||●UUID |
● Transmit Power
● Advertise Interval
|●Device Name |
|●Device Name |
●Sensor setting： temperature, humidity air pressure, motion
●immediately transmit， sample interval （ just for T&H sensor）
Bluetooth gateways can read and parse the broadcast packet data of the Beacon, and set the parameters of the beacon in the connection state. The setting content is the same as the Android/IOS SDK.
The product will running for BLE AoA protocol, the key parameters as below：
- Mode: Connectionless Mode，PHY in 1M PHY，
- Interval :100ms,
- CTE_TYPE = AOA_CTE
- CTE_LEN = 160uS,
- CTE_COUNT = 1
Otherwise, the BLE beacon card has a built-in accelerometer for active logic. After the Buetooth beacon card is left for more than 10min, the product enters sleep mode and will be awakened when motion is detected again.
