Product Introduction and Application
   JDY-33 Bluetooth is based on Bluetooth 3.0 SPP   BLE design, so it can support Windows, Linux, android, IOS data 

transparent transmission, working frequency band 2.4GHZ, modulation mode GFSK, maximum transmission power 6db, maximum 

transmission distance 30 meters, support users through AT Command to modify the device name, baud rate and other 

instructions, convenient and fast to use and flexible.

The advantages of JDY-33 are very obvious. It supports SPP and Bluetooth communication with the computer, supports 

mobile APP or WeChat applet, and can also support communication with the master and slave of the JDY-18 host.

 Applications
JDY-33 is classic Bluetooth   BLE dual-mode Bluetooth, which can communicate with Bluetooth-enabled computers (desktops, 

notebooks), mobile phones (android), and IOS. Can be applied

  ◆ Bluetooth POS machine

  ◆ Thermal printer

  ◆ Smart Home Control

  ◆ Automobile ODB testing equipment

  ◆ Application of various Bluetooth transparent transmission products

  ◆ Shared charging treasure, shared weight scale



Module parameters:
Model: JDY-33

Working frequency band: 2.4GHZ

Communication interface: UART

Working voltage: 1.8-3.6V (recommended 3.3V)

Working temperature: -40 ℃-80 ℃

Antenna: Built-in PCB antenna

Transmission distance: 30 meters

Master-slave support: slave

Module size: 26.7 * 13 * 1.7 mm (length, width and height)

Bluetooth version: Bluetooth 3.0 SPP   BLE4.2

SMT welding temperature: <260 ℃

Working current: 6.5mA

Deep sleep current: <10uA

Transmit power: 6db (maximum)

Receiving sensitivity: -96dbm

 

SPP maximum throughput:

16K bytes / s (android, windows)

When connected with Android and computer Bluetooth, the communication speed can reach 16k byte per second, and no packet 

loss (support serial port to send and receive data continuously)

 

BLE:

4K bytes / s (android, IOS)

When BLE is connected with IOS or Android, the communication speed is 4K per second (supports continuous transmission 

and reception of data at 38400 baud rate, it cannot be continuously sent above 38400 baud rate, and it takes time to add 

delay in the middle)
