Los Gatos, CA 95032
Initial production release version on BC04 modules supports 2.0
Changed behavior of PIO7/ DIP Switch 4, forces 9600 baud if set, regardless
of baud rate set in firmware.
New Bluetooth stack with 2.1 support
Added: command “S-,<name>” allows custom name with serialization
Added: CT (connect with timer) command
Added: support for SPP & DUN simultaneous profile appearance
Fixed: disconnect followed by a fast reconnect (< 100ms) would often cause
the module to go (deaf) making it undiscoverable or connectable, requiring
reset.
Fixed: <CR><LF> characters often were sent out the UARTwhen entering
fast data mode using the F,1 command remotely.
Added: S| command to reduce power while waiting for a connection
Added: CF, CFI, CFR commands for fast data mode connect
Added: L command to display Link Quality
Added: + command to toggle local echo of chars in command mode.
