3:有效通信距離15到30米
4:支持PWRC引腳控制睡眠
5:支持IO口控制斷開連接
二引腳功能說明
DISC引腳:用於主動斷開藍牙連接(默認高電平,低電平斷開連接)
PWRC引腳:用於喚醒睡眠(默 認處於睡眠狀態),使用當中此引腳接地才能發AT指令
VCC引腳:為模塊的電源引腳,供電電壓範圍3.6V到6V之間
GND引腳:電源地
TXD引腳:串口輸出引腳
RXD引腳:串口輸入引腳
三接線方法
此圖為透傳時的接線方式、目前DIS引腳沒有接,如果用戶是使用MCU與JDY-08模塊連接的話,DIS引腳可以接到MCU的IO口上。
四:AT指令: JDY-08為多功能模塊、AT指令具體請仔細閱讀JDY-08模塊標準手冊
JDY-08 Bluetooth transparent transmission module
Bluetooth main chip models: CC2541 Product Introduction JDY-08 transparent transmission module is based on the Bluetooth 4.0 protocol standard, the working frequency of 2.4GHZ range, modulation scheme is GFSK, the maximum transmit power of 0db, maximum transmission distance of 80 meters, the use TICC2541 chip design, allowing users to modify the device name through AT commands service UUID, transmit power, pairing password instructions, convenient to use and flexible. Description: The new V508 firmware upgrade to support serial Ultra-low standby power consumption 400uA ~ 800uA Ultra-long connection distance 100 ft / 60 m Fast reaction speed 0.4 seconds For Apple, Android Receive no byte limit, up to 6K Bytes / sec. MFI does not need to do Android 4.3 perfect support.
Feature
- Tested on 3V3
- Module enter into data transmission mode when it paired.
- Pull P00 to low to wake up the module from sleep mode, then module can accept data tranmission.
- serial data send need “/r/n”
- Power supply must use 3.3 or 3V for final products
- master module can only allow one slave module connect
- in room distance is 15-30 meters, max to 60 meters.
- Tranmission data speed is 1KB/s
- Do not support 2.0 or 3.0 bluetooth version.
Operating mode state current
- Slave Transparent Mode Connected / Not Connected / Standby 0.8mA / 300uA / 1uA
- Slave Broadcast mode (IBeacon, sensor) Connection / Not connected / Standby 0.5mA / 300uA / 1uA
- Host Transmitted Mode Connect / Unconnected / Standby 20mA / 9mA / 1uA
- Host observer mode (Sensor) connected / not connected / standby 25mA
