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.

MESH Short Address Table (MADDR)
Address | Function | Explain |
0XFFFF | Broadcast address | The device short address cannot be configured as 0XFFFF |
0X0002到0XFF00 | Unicast address | Device address (user set short address can be within this range) |
0X0001 | Central machine address | Central machine |
0xFF01到0XFFFE | System address | Generally not recommended for use |
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
Command Name | Address | Explain |
DATA_NO_ACK | 0x00 | Sending data to the target device without response |
DATA_ACK | 0x01 | Sending data to the target device with a response |
IO_NO_ACK | 0x10 | Control target device IO no response |
IO_ACK | 0x11 | Control target device IO response |

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 | HEAD 7byte | CMD 1byte | Target MMADDR 2byte | Data (1-17)byte | End symbol 1byte |
1 |
41 54 2b 4d 45 53 48 |
00 | FFFF | 112233445566 |
0D0A |
2 | 0005 | 1122 | |||
3 | 01 | 0008 | 88990055 |
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
