Main Features

Product introduction:

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.

AwakenBroadcast4. 9mAGenerally speaking with APP, it is  suggested that broadcasting should not be too long and too long to affect connection time. It is generally recommended between 100 and 500mS, such as fast connection and no demand for power consumption. The broadcast interv al can be set to the  shortest possible.

2PWM1Support UART, IIC, APP control
3PWM2Support UART, IIC, APP control
4104High and low levels can be controlled by APP
6STATUART 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
9101High and low levels can be controlled by APP
10102High and low levels can be controlled by APP
13103High and low levels can be controlled by APP
14PWH3Support UART, IIC, APP control
15TO4Support UART, IIC, APP control
17ALKDBroadcast scintillation, frequent connection after connection (master and slave effectiveness)
18RTCARTC timing time produces the falling edge interrupt signal, normally high level.
SELECT boot for high power, this pin function is serial TXD.
SELECT boot for low power, this pin function is IIC DD
20RXD_0R_DCSELECT boot for high power, this pin function is serial RXD.
SELECT boot for low power, this pin function is IIC DC
21SELECTUART 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.
22PWRCDown 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.

Serial AT instruction set:
JDY-17 module serial port to send AT instructions must add rn, AT is not case sensitive.
