JDY-25M Super BLE Bluetooth Module

Key label detection is generally used in gate switch, check in, anti-loss and other fields.

When JDY-25M detects the key label or bracelet approaching, OUT outputs pin action.

Example: the MAC of the bracelet is 112233445566. When the bracelet is close, the OUT2 pin

action instruction is as follows.

AT+ROLE8

AT+KLABEL1,2,112233445566

AT+RESET

JDY-25M supports binding 10 labels and 5 action OUT pins. The received label address will

be output from the serial port. If you need to expand the number of labels, you can set the

label address to the same, so that JDY-25M will have no upper limit on the number of labels,

and users can also get the label address through MCU added by the serial port and to

process MCU.
