===Use PC to Debug===
−
**Microduino-Core32u4 module can use the USB to simulate the serial 0, and BT uses the 32u4's serial 1 (RX0,TX1), so you don't need to change the existing jumper (RX0,TX1) and it won't impact program download or the serial port's function.
+
*Debug by serial port:  
−
 
+
**Do not stack [[Microduino-USBTTL]] directly and cross connect RX(D4) and TX(D5) of [[Microduino-USBTTL]] and [[Microduino-BT]].
−
*Microduino Shield BT4.0 uses the default serial RX0,TX1 to communicate with Core module, so it can be directly connected with Microduino FT232.

FQA

  • This module can’t make pair with win7?
    • Check the BT version in win7, this module only support BLE 4.0 version and default password is 000000.
  • Does this module can reset by button?
    • No, it can be reset by power down.
  • This module can’t make pair with iphone and Android phone?
    • This issue mostly is caused by the BT version. This module only supports BT4.0 protocol.
    • For Andriod OS: 4.3 release
    • For IOS: iPhone4s upper, iPod touch 5 upper, iPad 3 upper and iPad mini upper
