JDY-25M Super BLE Bluetooth Module

This circuit is mainly used for routing nodes. The key supports to control the IO or serial port

output key information of all nodes (routing, terminal) in the network.

Network IO control instructions are as follows:

AT+ROLE5

AT+RESET

After configuration, IO control can be carried out. By default, the short address of INPUT1 to

INPUT5 is FFFF. Press the INPUT pin SW key by default to output IO to control the

corresponding OUTPUT of all devices in the network. If you do not need to control the OUTPUT

pin of all devices, you can configure it with the following instructions.

Example 1: The INPUT5 key with the local machine address of 0005 needs to control the

OUTPUT5 pin level of 0008 device

0005 local machine instruction as follows: AT+KEY5,0008,5,0

Example 2: The INPUT1 key with the local machine address of 0005 needs to control the

OUTPUT3 pin level of 0008 device

0005 local machine instruction as follows: AT+KEY1,0008,3,0

Note that this mode is non learning mode key switch and output IO control. AT+LEARN0 and

AT+SUBTYPE0 are both set to 0, and the module factory default is 0.
