Re-programming OLED as a GPS display

[KeithRB]

I have a QStarz datalogging GPS fob, which has no display. I would like to add a display to it so that I can sync my camera clock for GPS tagging. I have an OLED, and was thinking I could marry a BlueSmirf Bluetooth modem to the OLED to display data from the GPS.

The BlueSmirf defaults to 9600 Baud. Once I have things set up and a GPS sentence is coming in once-per-second, would it be better to use serin with the "$GPGGA" qualifier or the hserin command?

As a blocking HSERIN only allows a single qualifier it would seem SERIN would be better with its multiple byte qualifiers.

On the M2 (the processor on the OLED), I don't even have the option of a qualifier with the Hserin command, anyway, I would just have to poll it, which would probably be pretty much a blocking loop anyway.
