JDY-17 bluetooth 4.2 Module High Speed Data Transmission Mode BLE Mesh Networking Low Power Bluetooth Module
The JDY-17 transmission module is based on the bluetooth 4.2 protocol standard, the working band is 2. 4GHZ range, the modulation mode is GFSK, the maximum transmission power is Odb, the maximum launch distance is 60 meters. The import original chip is designed to support the user to modify the equipment name, service UUID, transmit power, match the password and so on through the AT command. Czechoslovakia is flexible.
JDY-17 bluetooth module can realize data transmission of module and cell phone or module and module, and can choose UART or IIC communication mode through I0, and BLE bluetooth can be used for product application quickly through simple configuration.

Pin function description:
| Pin | Function | Explain |
| 1 | VCC | Power supply <1.8-3 |
| 2 | PWM1 | Support UART, IIC, APP control |
| 3 | PWM2 | Support UART, IIC, APP control |
| 4 | 104 | High and low levels can be controlled by APP |
| 5 | NULL | |
| 6 | STAT | UART communication mode: unconnected low level, high level aft er connection. IIC communication mode: no connection to high level, connection, disconnection or reception will be interrupted by “interrupt” work, interrupt down edge hold time 200ms |

TXD_0R_DD |
SELECT boot for high power, this pin function is serial TXD. SELECT boot for low power, this pin function is IIC DD |
| 20 | RXD_0R_DC | SELECT boot for high power, this pin function is serial RXD. SELECT boot for low power, this pin function is IIC DC |
| 21 | SELECT | UART or IIC selection pin Open low level: IIC communication mode Open high level: UART communication mode The default SELECT is suspended to high level: UART communication mode. When the user needs IIC, the SELECT pin should be grounded. |
| 22 | PWRC | Down wake-up, when the AT command needs to be sent in the connection state, the AT instruction mode can be expressed by keeing this pin low level, and the pin is AT instruction mode at high and low levels in the unconnected state. |
| 23 | RESET | Hardware reset pin |
| 24 | GND | Power supply |
Serial AT instruction set:
JDY-17 module serial port to send AT instructions must add rn, AT is not case sensitive.
