1、 Product Introduction and Application

JDY-31 Bluetooth is designed based on Bluetooth 3.0 SPP, which supports transparent data transmission for Windows, Linux, and Android. It operates in a 2.4GHz frequency band, uses GFSK modulation, has a high transmission power of 8db, and a large transmission distance of 30 meters. It supports users to modify device names, baud rates, and other commands through AT commands, making it convenient, fast, and flexible to use.

2、 Product application

JDY-31 is a classic Bluetooth protocol that can communicate with Bluetooth enabled computers (desktop, laptop) and mobile phones (Android). Can be applied to

◆ Windows computer Bluetooth serial port transparent transmission

◆ Android Bluetooth serial port transparent transmission

◆ Smart home control

◆ Automotive ODB testing equipment

◆ Bluetooth toys

◆ Shared power bank, shared weight scale

◆ Medical equipment

4、 Pin functions and applications

详情-01

JDY-31 supports SMT and soldering pin arrangement

1. Needle setting application: The needle setting specification is a standard 2.54 pitch needle setting, which only requires welding 5 needle setting holes on the module.

2. Surface mount application: Generally, only four pins VCC, GND, RXD, and TXD need to be connected. If active disconnection is required in the connected state, send AT+DusC in the connected state
