Product introduction:

 
JDY-08 passthrough module is based on Bluetooth 4.0 protocol standard, the scope of work frequency of 2.4 GHz, modulation method for GFSK, maximum transmitted power of 0 dB, the largest launch distance of 80 meters, adopt TICC2541 chip design, support the user through the AT command to modify the device name, service UUID, transmission power, such as matching password instructions, convenient use and flexible.
 

Function introduction:
 

1.  App pass-through (supports AirSync protocol, applies to WeChat H5 or factory server communication, including long packet data parsing and sending and receiving)
2.  App transmission (support Android and IOS data transmission)
3.  iBeacon mode (support WeChat shake protocol and apple iBeacon protocol)
4.  Sensor mode (temperature, humidity, and many other sensor data acquisition applications)
5.  Host transmission mode (data transmission between application modules, communication between host and slave)
6.  Host observer mode (application sensor, indoor positioning)
7.  PWM mode (used for motor speed regulation and LED light brightness adjustment)
8.  I/O mode (for mobile phone control relay or LED on/off)
9.  Indoor chamber location application (application of collecting iBeacon data to achieve range positioning)
10.  RTC mode
11.  
12. RTC alarm mode: the alarm time of RTC can be set to control 10 ports, and two alarm time settings are supported
     

Technical parameters:

1.  The communication rate is 3K Bytes/ second
2.  1024Bytes can be written in the serial port of APP transmission
3.  The effective communication distance is 15 to 30 meters
4.  Support PWRC pin to control sleep
5. Support IO port control disconnect

Electrical characteristics:

Working mode:

Slave transmission mode connected / not connected / standby 0.8ma/300ua/1ua
Slave broadcast mode (ibeacon, sensor) connected / not connected / standby 0.5ma/300ua/1ua
Host transmission mode connected / not connected / standby 20mA / 9ua / 1uA
Host observer mode (sensor) connected / not connected / standby 25mA
