Product introduction:

The Bluetooth-compatible function of JDY-24M networking supports master-slave transparent transmission, iBeacon, BLE probe, iBeacon detection, MESH networking, and the maximum number of MESH networking supports 65535 device networking, using multi-hop wireless anti-collision technology, and networking communication speed support 50mS sends 17 bytes of data, a single module supports routing nodes and terminal nodes, routing nodes support data relay (low power consumption is not supported), terminal nodes support low power consumption (automatic sleep after pressing the key to wake up after sending data), JDY-24M Networking generally only needs to configure the network NETID and short-circuit address, and the module will automatically network. When the network module communicates with the APP, it is equivalent to transparent transmission, which greatly facilitates users to develop APP compatible with the old product APP.

Product Features:

1: Support the transparent transmission of APP data with mobile phones (IOS, ANDROID) (working current is about 1mA)

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-compatible probe function

6: Support multi-linked slave mode, multi-linked slaves can be connected with multiple mobile phones, and transparent transmission at the same time

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

8: MESH networking sends data to support response and non-response communication

Application circuit reference:

Note:General transparent transmission only needs to connect 4 wires (VCC, GND, RXD, TXD), MCU can judge the working status of Bluetooth-compatible (connected, disconnected) through the serial port status, if Bluetooth-compatible output status (connected, disconnected ), JDY-24M non-MESH master-slave transparent transmission wiring diagram can be judged by the Bluetooth-compatible status pin or by pulling the PWRC pin low (send AT + STAT)

The master-slave communication rate supports continuous sending and receiving of data at all baud rates (at 115200 baud rate, data can be sent without delay and can be sent and received continuously)

Host command: AT + ROLE1
AT + RESET
Search slave command: AT + INQ
After searching for the slave, use AT + CONA plus the searched MAC address of the slave to connect


Default factory configuration:

The default is networking mode, AT+ROLE5

The serial port baud rate is 9600

The network ID number is 1189

The network short address is the last two bytes of the MAC address

All nodes support relay function

Pin description:

EN: wake up from sleep or send AT command after the connection state is pulled down

The button on the bottom board is connected to the EN pin

VCC: power supply (3.6-6V)

GND: power ground

TXD: Serial output pin, TTL level

RXD: serial port input pin, TTL level

STATE: connected state pin, output low level when not connected, output high level after connection
