Features: 1JDY-18 si compatible with BLE 4.2 protocol and development compatible with BLE5.0, which is better than mobile phone compatibility than CC2541 module. 2RF TX and RX peak current 5 to 6 mA, CC2541 peak current more than 10mA, JDY-18 is more energy efficient than CC2541 module at low power consumption, lower power consumption, such as electronic lock, or battery-powered products, generally It is more recommended to use the JDY-18 module, the average power consumption is at least half of JDY-08 It can also be used to transfer pictures on the printer 3The JDY-18 module can transmit at a rate of more than 8K per second. The master-slave communication supports 115200 baud rate for continuous transmission and reception, and does not lose packets. The serial port test tool uses SSCOM test. 4The JDY-18 supports UART or IIC communication interfaces, which can be applied to lower cost MUC applications. 5JDY-18 supports SIG standard MESH, and JDY-16M supports MESH networking. 6JDY-18 operates fast and has a great performance 7Support users to modify the device name, service UUID, transmit power, pairing password and other commands through the AT command, which is convenient and quick to use. 8The JDY-18 module compatible with Bluetooth can realize module and mobile phone or module and module data transmission. It can select UART or IIC communication mode through IO, and can quickly use BLE Bluetooth for product application through simple configuration.
