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 linvor1.5 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.
