Product introduction:

The Bluetooth-compatible function of JDY-24M network supports master-slave transmission, iBeacon,BL E probe, iBeacon detection, MESH networking, MESH networking maximum support 65535 device networking, multi-hop wireless collision avoidance technology, networking communication speed supports 50mS to send 17 bytes of data, single module supports routing node and terminal node, routing node supports data relay does not support low power consumption, terminal node supports low power consumption (automatic sleep after keystrokes wake up after sending data), JDY- 24m networking generally only needs to configure the networking NETID, short-circuit address, the module will automatically network networking module and APP communication is equivalent to transmission, so that it is very convenient for users to develop APP compatible with the APP of old products.

Product characteristics:

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)
