1、 Product Introduction
The JDY-23 transparent transmission module is based on the Bluetooth 5.0 protocol standard, with a working frequency range of 2.4GHz, modulation mode of GFSK, transmission power of 4db, and transmission distance of 60 meters. It is designed with imported original chips and supports users to modify device names, baud rates, and other commands through AT commands, making it convenient, fast, and flexible to use.
The JDY-23 Bluetooth module can achieve data transmission between the module and the mobile phone, and can quickly use BLE Bluetooth for product applications without configuration by default.
Make BLE more efficient and convenient in product applications
