JDY-28M Bluetooth Module MESH Networking Module Bluetooth Transparent Transmission Module BLE5.2Item NO.: JDY-28M

JDY-28M Bluetooth Module

Product Description:

The JDY-28M Bluetooth module protocol is version 5.2, which integrates master and slave, and supports configuration of multiple modes (BLE master-slave transparent transmission mode, MESH transparent transmission mode, MESH command mode, car key, switch panel, MESH low-power remote control). BLE transparent transmission test supports 20K Bytes per second rate, MESH mode supports networking status LED lights, and the module comes with networking indicator LED lights. MESH devices and devices support 1K Bytes transparent transmission rate in networking status. MESH transparent communication does not require data head and tail, and can replace 485 communication. MESH relay time is less than 5ms, and the minimum outsourcing interval for MESH is less than 5ms. Send 20Byte data within 20ms. In car key mode, it supports binding 5 mobile phones separately. The automatic unlocking distance and departure locking distance can be configured through commands, and 5 mobile phones can be managed through commands. When binding mobile phones, it supports button binding. After connecting to the APP, the APP sends commands for binding. The switch panel mode supports one key synchronous control of multiple switches or single switches or multiple switch mutual control, supporting one key full open and full close functions. Each switch comes with a relay function, which allows for longer transmission distance between modules. In MESH mode, multiple modules communicate, and the phone will not search for multiple BLE broadcasts, greatly improving stability and anti-interference ability
