ماژول بلوتوث JDY-33 DUAL MODE BLUETOOTH:
Introduction:
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 quick to
use and flexible.
The advantages of JDY-33 are very obvious. It supports SPP and computer Bluetooth communication, supports mobile APP or WeChat
applet, and can also support communication between JDY-18 host and slave.
Application:
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
1. Bluetooth POS machine
2. Thermal printer
3. Smart Home Control
4. Automobile ODB testing equipment
5. Application of various Bluetooth transparent transmission products
6. Shared charging treasure, shared weight scale
ماژول بلوتوث JDY-33 DUAL MODE BLUETOOTH
Parameter:
Model: JDY-33

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

Working current: 6.5mA
Deep sleep current: <10uA
Transmitting 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)
The communication speed when BLE is connected with IOS or Android is 4K per second (supports continuous sending and receiving of
data at 38400 baud rate, it cannot be sent continuously higher than 38400 baud rate, and it takes time to delay in the middle)
شرح پین ها:
JDY-33 general application only needs to connect the 4 pins of VCC, GND, RXD, TXD, if disconnected in the connected state, send AT
+ DISC \ r \ n, and need deep sleep in the unconnected state to send AT + SLEEP \ r \ n, after deep sleep, you can wake up through
the falling edge of the EN pin, or you can send data through the serial port to wake up. It is generally recommended to use the
serial port to send the AT + VERSION \ r \ n command to wake up
