1.Introduction
DSBC-120 is a portable BLE beacon card suitable for indoor positioning, asset tracking, 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. Caution
- Being close to a metal object will interfere with the signal of BLE beacon card, causing the signal to be weakened.
- Note the distance between DSBC-120 beacon card and the receiver to guarantee the accuracy of receiving.
- Keep DSBC-120 beacon card away from corrosive objects.
6. Reference Usage
1)BLE Beacon card broadcasts the data.
2)Bluetooth Gateway then gets the boradcasted data and sends the data to Cloud via Wi-Fi or LTE once per second.

1) The BLE beacon card will always want to send a broadcast packet nearby at a certain frequency.
2) A Bluetooth-enabled mobile phone can receive the beacon information and parse the data through the APP.

7. Sofeware Development
The mobile phone can read and parse data of BLE beacon cards and set parameters through APP.

●Device Name ●Transmit Power ●Advertise Interval ●Password ●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 BLE beacon cards, 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,
- UUID16=0x184A。
- 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.
