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.

Command	Response	Note
AT	OK	Usefull to check connection and baudrate
AT+VERSION	Linvor1.5	Get the version of the module
AT+BAUDx	OKyyyy	Set the baudrate. x can take the following values: 1 for 1200 bps, 2 for 2400 bps, 3 for 4800 bps , 4 for 9600 bps, 5 for 19200 bps, 6 for 38400 bps, 7 for 57600 bps, 8 for 115200 bps , 9 for 230400 bps, A for 460800 bps, B for 921600 bps, C for 1382400 bps
