JDY-33 Dual mode Bluetooth serial Port Bluetooth SPP-C compatible with HC-05/06 slave Bluetooth 3.0

1. Product introduction and application

JDY-33 Bluetooth is based on Bluetooth 3.0 SPP+BLE design, which can support Windows, Linux, android, IOS data transparent transmission, working frequency band 2.4GHZ, modulation mode GFSK, transmission power 6db, transmission distance 30 meters, support users to modify through AT commands Commands such as device name and baud rate are convenient and flexible to use.

The advantages of JDY-33 are very obvious. It supports Bluetooth communication between SPP and computer, supports mobile phone APP or WeChat applet, and also supports communication with JDY-18 host master and slave.

2. Product application

JDY-33 is a classic Bluetooth + BLE dual-mode Bluetooth, which can communicate with computers (desktops, notebooks), mobile phones (android) and IOS that support bluetooth. can be applied to

◆ Bluetooth POS machine

◆ Thermal Printer

◆ Smart Home Control

◆ Automotive ODB testing equipment

◆ Application of various Bluetooth transparent transmission products

◆ Shared power bank, shared weight scale
