5pcs JDY-17 Bluetooth 4.2 Module High Speed Data Transmission Mode BLE Mesh Networking Low Power

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.

Working current:

Working mode	Broadcast state	Current	Remark
Awaken	Broadcast	4. 9mA	Generally 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.
Deep sleep free sleep	NO broadcast	1.38uA
Shallow sleep has radio sleep	100mS Broadcast interval	280uA
Average power consumption	200mS Broadcast interval	140uA
	300mS Broadcast interval	80uA
	400mS Broadcast interval	The following current is lower
	500mS Broadcast interval
	600mS Broadcast interval
	700mS Broadcast interval
	800mS Broadcast interval
	900mS Broadcast interval
	1000mS Broadcast interval
internal state of arousal	Already connected	4. 93mA	In connection state, you can check the  AT +STARTEN instruc tion by pulling the PWRC pin down and Issuing the AT instruction or the direct pivoting mode.
Sleep state	Already connected	50uA

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
7	NULL
8	NULL
9	101	High and low levels can be controlled by APP
10	102	High and low levels can be controlled by APP
11	NULL
12	MILL
13	103	High and low levels can be controlled by APP
14	PWH3	Support UART, IIC, APP control
15	TO4	Support UART, IIC, APP control
16	MILL
17	ALKD	Broadcast scintillation, frequent connection after connection (master and slave effectiveness)
18	RTCA	RTC timing time produces the falling edge interrupt signal, normally high level.
19	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.
