I changed the TeleGPS firmware so that it just keeps appending data to a single log buffer instead of the separate flight buffers present in our flight computers. There is 2MB of storage on the board, of which 64kB is used to store configuration parameters, leaving 1984kB of space for the log. I did this because several fliers noticed that simply power cycling the board a couple of times while testing things would "fill up" all available log space on the device, leaving it unable to log data for the actual flight. > It records flights (simulated by putting in my pocket while going on a run > around the neighborhood.

Right, there should be only a single "flight" on the device at any time. > At this point I still can't change the maximum log size. I'm using the > TeleGPS app 1.6.5 and I've updated firmware to telegps-v1.0-1.6.5. Given the above description, do you think the firmware is doing something wrong? I'm thinking of how I might change the ground software to take the single log and split it into sensible "flights"; with GPS date information, I should be able to identify sections of the log that are close together in time. -- -keith
