!!!before all: please be CAREFULL, you can destroy electric parts.!!! You have two options for connect BT module to PC. 1) you can use some FTDI (usb <=> serial), with 3.3V logic. Like this http://www.dx.com/cs/p/ftdi-basic-progr ... UMNiBfdLnY 2) you can use cable from spirit (usb pc cable), but you have to add some axternal power (4V - 6V, !!!6.5V is DEADLY for BT module!!!), do you need better wiring? Attachment: bt-wiring.png RX to orange on spirit USB cable TX to red on spirit USB cable or can be inverted, it depend on marking USB module. For communication with BT module you can use some PC SW like this http://www.compuphase.com/software_termite.htm#_ . Your BT module look like JY-MCU http://www.instructables.com/id/Success ... th-Module/. Different type BT module can use other commands. AT -> response OK AT+BAUD7 -> response 57600 for more onfo http://ecno92.blogspot.cz/2012/11/jy-mc ... -name.html (search text "List of available ATcommands:") Its all. ----------------------------------------------------------------------------------------------------- And again, please be carefull you can destroy PC, USB cable and BT module. A better way is to buy original BT module. ----------------------------------------------------------------------------------------------------- |
