one. Overview
 
BT16 4.2 Bluetooth transparent transmission module using Airoha latest Bluetooth 4.2 BLE single chip AB1602, through the embedded data transmission dedicated service to achieve based on GATT Bluetooth data transmission. BT16 4.2 Bluetooth transparent transmission module supports serial command mode, used to achieve the external MCU and module interaction. Users can use the serial port command to configure the parameters and some control, such as modify the UUID, modify the Bluetooth name, control Bluetooth disconnect, etc.
 
two. Features:
 
Bluetooth protocol: Bluetooth Specification V4.2 BLE, send and receive no byte restrictions, have far more than traditional Bluetooth
 
Of the distance of communication
 
Operating frequency: 2.4GHz ISM band
 
Modulation: GFSK (Gaussian Frequency Shift Keying)
 
Sensitivity: -84dBm at 0.1% BER
 
Security features: Authentication and encryption
 
Support services: Central & Peripheral UUID FFE0, FFE1, FFE2 (FFE0 for service UUID, FFE1 for read data channel, FFE2 for write data channel)
 
Power consumption: low power mode: standby current 200-270uA, transmission 1mA.
 
Normal operating mode: standby 4mA, transmission 4.17mA.
 
Power supply: 3.3VDC 50mA
 
Dimensions: 18mm x 14.5mm x 2mm
 
Bluetooth certification: BQB ROHS REACH
 
Transmission distance: 10-12 meters
 
Transfer rate: This module sends up to the mobile phone data can send up to 280 bytes each time, such as more than send the packet (such as a transmission of more than 280 bytes, the module will crash).
 
three. Application areas:
 
The module is mainly used for short-range data wireless transmission. Can be easily connected with the PC's Bluetooth device, you can also communicate with the smart phone data. To avoid tedious cable connection, can directly replace the serial line.
