In Arduino IDE V1.5.7 and V1.5.8 for Windows, I get the following error when i try to compile OpenBCI_8bit_SD.ino ...

SDcard.ino:57:1: error: 'prog_char' does not name a type
SDcard.ino:58:1: error: 'prog_char' does not name a type
SDcard.ino:59:1: error: 'prog_char' does not name a type
SDcard.ino:60:1: error: 'prog_char' does not name a type
SDcard.ino:61:1: error: 'prog_char' does not name a type
SDcard.ino:63:1: error: 'prog_char' does not name a type
SDcard.ino:64:1: error: 'prog_char' does not name a type

This prevents the program from compiling.

I found a workaround (see http://openbci.com/forum/index.php?p=/discussion/271/prog-char-does-not-name-a-type#latest), but IMO the code should be fixed so that they can compile without making any changes.

This is a data capture from the OpenBCI dongle:

https://github.com/keturn/txOpenBCI/blob/75ca8829ddb1ade40ae86e7bfebaa8c6891eb0a2/txopenbci/test/stream_with_bad_end.raw

The data stream begins with data in the expected protocol format, but at the end there are three samples that are missing their 0xA0 / 0xCO delimiters.

My hunch is that the host rfduino code decided to drop out of streaming mode before it received these last three packets, because it does that when it receives the 's' input from the PC, not when the stream is finished.

(32-bit device, but I think this issue is about the code on the rfduinos, which is 8bit.)
