JDY-28M Bluetooth module MESH networking module Bluetooth transparent module BLE5.2 module

1、 Product Description
JDY-28M Bluetooth module protocol is version 5.2, which integrates master and slave. It supports multiple modes (BLE master-slave transparent mode, MESH transparent mode, MESH command mode, car key, switch panel, MESH low-power remote controller). The measured BLE transparent transmission supports 20K Byte per second, MESH mode supports networking status LED, and the module has its own networking indicator LED. MESH devices and equipment support 1K Byte transparent transmission rate under networking status, MESH transparent transmission communication does not require data head and tail, and is completely transparent transmission, which can replace 485 communication. MESH relay time is less than 5ms, and the minimum MESH sending interval is 20ms to send 20Byte data. Under the car key mode, five mobile phones can be bound respectively. The automatic unlocking distance and departure locking distance can be configured through commands. The five mobile phones can be managed through commands. When binding a mobile phone, it supports key binding. After connecting with the APP, the APP sends commands to bind. The switch panel mode supports one key synchronous control of multiple switches or single switch or multiple switches for mutual control. It supports one key full open and full close functions. Each switch has its own relay function, In this way, the transmission distance between modules is longer, multiple modules communicate in MESH mode, and the mobile phone will not search multiple BLE broadcasts, greatly improving the stability and anti-interference ability
