From bb7522acf040f41740ecd059e3d5d2480b652420 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Sun, 17 Aug 2014 20:59:45 -0700 Subject: telegps-v1.0: Provide one log and append to it Instead of creating per-flight logs, create a single log and append data to it each time TeleGPS is powered on. This avoids potentially running out of log space just because the device is powered off/on.
