Pin function description:
| Pin | The name of the discipline | Function |
| 1 | GPI01 | Input-output IO, which can be configured by AT+CLSS |
| 2 | GPI02 | Input-output IO, which can be configured by AT+CLSS |
| 3 | GPI03 | Input-output IO, which can be configured by AT+CLSS |
| 4 | GPI04 | Input-output IO, which can be configured by AT+CLSS |
| 5 | GPI05 | Input-output IO, which can be configured by AT+CLSS |
| 6 | GPI06 | Input-output IO, which can be configured by AT+CLSS |
| 7 | GPI07 | Input-output IO, which can be configured by AT+CLSS |
| 8 | GPI08 | Input-output IO, which can be configured by AT+CLSS |
| 9 | VCC | Power supply (2.2-3.6) |
| 10 | RXD | Serial port input pin |
| 11 | TXD | Serial port output pin |
| 12 | SET | AT command switching pin (low level AT instruction, high level transparent transmission) |
| 13 | CS | Transmission or push button mode: CS pin (low level wake-up, high level sleep). _x000D_ IO receive mode:the CS pin needs to be suspended or pulled up |
| 14 | GND | Power supply |
Default configuration:
| sequence | function | parameter | instructions |
| 1 | baud rate | 9600 | AT+BAUD |
| 2 | wireless ID | 8899 | AT+RFID8899 |
| 3 | device ID | 1122 | AT+DVID1122 |
| 4 | channel | 001 | AT+RFC001 |
| 5 | emissive power | 12db | AT+POWE9 |
| 6 | equipment type | A0 | AT+CLSSA0 |
Communication:
It is necessary to configure the RFC, DVID, and RFID that need the communication module to be the same. The module and the module can communicate. When the module comes out, the parameters are all unified, and the user can configure it according to its own needs.
AT instruction instructions:
_x000D_
Specifically, the JDY-40 module needs to add the ending symbol rn to send the AT instruction.
Set / query - baud rate:
| instructions | response | response |
