ماژول بلوتوث JDY-33 DUAL MODE BLUETOOTH:

ماژول بلوتوث JDY-33 DUAL MODE BLUETOOTH  در واقع ماژول بلوتوث دو حالته (SPP + BLE) می باشد. که با سازگار با ماژول های بلوتوث معروف همانند HC05 و HC06 است. می تواند از ویندوز ، لینوکس ، iOS ، انتقال داده اندروید ، فرکانس کار 2.4GHZ ، حالت مدولاسیون GFSK ، حداکثر قدرت انتقال 5db ، حداکثر فاصله انتقال 40 متر پشتیبانی کند. از کاربران پشتیبانی می کند تا نام دستگاه ، نرخ باود و سایر دستورات را از طریق دستور AT تغییر دهند که استفاده از آن راحت و سریع است.
JDY-33 یک پروتکل بلوتوث کلاسیک است که می تواند با رایانه های مجهز به بلوتوث (دسک تاپ ، نوت بوک) و تلفن های همراه (اندروید) ارتباط برقرار کند. قابل بکارگیری است.

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
