AT Commands

Da http://byron76.blogspot.it/2011/09/one-board-several-firmwares.html

           ...boards seem identical, they had different firmwares. 
The suntekstore ones has HC05 firmware, the DealExtreme ones has linvor

           1.5 firmware.
           The differences between them is mainly the AT command
           set.Linvor 1.5 also known as HC06
           This firmware offers a very limited set of AT command.
           By default the baudrate is 9600 8N1.

           For this firmware you have to not send LF or CR
           character at the end of your AT command.AT programming mode is up
           when your board is not paired by bluetooth devices. For this
           firmware, you have to copy/paste AT command since timings is
           important. You can send about one command per second.
