1、 Product Introduction

The JDY-24M networking Bluetooth function supports master-slave transparent transmission, iBeacon, BLE probes, iBeacon detection, MESH networking. With a large number of MESH networking devices, it supports 65535 device networking and adopts multi hop wireless anti-collision technology. The networking communication speed supports 50mS to send 17 byte data. The single module supports routing nodes and terminal nodes, and the routing nodes support data relay (do not support low power consumption). The terminal nodes support low power consumption (automatically sleep after pressing the button to wake up and send data). JDY-24M networking generally only requires configuring the networking NETID and short-circuit address, and the module will automatically network. When the networking module communicates with the APP, it is equivalent to transparent transmission, which greatly facilitates user development of APP and compatibility with old product APPs.

2、 Product Features

2: Support module and module master-slave high-speed transparent transmission

3: Support iBeacon function (ultra-low power consumption)

4: Support iBeacon probe function

5: Support BLE Bluetooth probe function

6: Supports multiple slave modes, which can be connected to multiple mobile phones and transmitted transparently at the same time

7: Supports Bluetooth MESH (network serial port data communication, output IO control, input button control)

8: MESH networking supports both response and non response communication for sending data

9: Networking remote control

5、 Factory default configuration

6、 Module pin definition

Serial port AT instruction set

The JDY-24M module's serial port must include the AT command when sending it

MESH Short Address Table (MADDR)

Explanation: Short addresses are equivalent to device ID numbers within the network

          Broadcast data can be received by all devices within the network

            Single broadcast data, only devices with specified addresses can receive the data

CMD Command Table

Explanation: MESH communication data includes packet header+CMD+MADDR+DATA. This table is the CMD command table and requires serial communication with return numbers

According to time, the instruction address is 0x01, and when an IO return control instruction is required, the instruction address is 0x11.

Serial port sends MESH serial port data to the target device

Example 1: Broadcast serial port data is sent to all devices in the network, and all devices in the network output 112233445566 serial ports

       Complete instruction: 41 54 2b 4d 45 53 48 00 FF FF 11 22 33 44 55 66 0D0A

Example 2: Send serial data to device 0005 in the network, with data content of 1122

Example 3: Sending serial data to device 0008 in the network with a response, the data content is 88990055. When CMD is 01, it indicates that there is a response communication,

The transmitting end can know whether the data has been received by the receiving end

Explanation: Examples 1 to 3 have already demonstrated that in networking, devices send serial communication data between themselves. Please note that the data is in hexadecimal format
