1、 Product Introduction and Application
JDY-33 Bluetooth is designed based on Bluetooth 3.0 SPP+BLE, which supports transparent data transmission for Windows, Linux, Android, and IOS. It operates in a 2.4GHz frequency band, uses GFSK modulation, has a transmission power of 6dB, and a transmission distance of 30 meters. Users can modify device names, baud rates, and other commands through AT commands for quick and flexible use.
The advantages of JDY-33 are very obvious, supporting SPP and computer Bluetooth communication, supporting mobile APP or WeChat mini program, and also supporting communication between JDY-18 host and slave.
2、 Product application
JDY-33 is a classic Bluetooth+BLE dual-mode Bluetooth that can communicate with Bluetooth enabled computers (desktop, laptop), mobile phones (Android), and IOS. 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

SPP throughputSPP | 16K bytes/s (Android, Windows) When connected to Android or computer via Bluetooth, the communication speed can reach 16k bytes per second without packet loss (supporting continuous data transmission and reception via serial port) |
BLE | 4K bytes/s (Android, iOS) When BLE is connected to IOS or Android, the communication speed is 4K per second (supporting continuous data transmission and reception at a baud rate of 38400, but cannot be continuously transmitted at a baud rate higher than 38400, with additional delay in between) |
4、 Pin functions and applications
JDY-33 generally only needs to connect the VCC, GND, RXD, and TXD pins for general applications. If the connection is disconnected in the connected state and AT+DusC is sent, deep sleep is required to send AT+SLEEP in the unconnected state. After deep sleep, it can be awakened by the EN pin's falling edge or by sending data through the serial port. It is generally recommended to use the serial port to send the AT+VERSION command to wake up.
