orangeLearner:
Do we have the same board? Mine says JY-MCU BT_BOARD 1.02. If it is the same board then I do not know how to proceed save for searching online.
I have same board (JY-MCU BT_BOARD V1.02), but here: http://www.ebay.com/itm/150763254858 says that default baud rate is 9600 and I tried with 38400 and 9600 and it works only with 9600.
But another problem: when I type AT I get OK, but when I type AT+VERSION (or ATVERSION, like You said before) I get nothing.
Maybe You connected State or Key pins on BT board?
Thanks!
