Ok, so I got around to testing this.
echo "0 1000 10 2550 0 1000 0 100" > pattern
makes expected pattern [ .-xXx-. ].
But when I do
echo "0 1000 10 2550 0 1000" > pattern
I only get expected pattern on the first iteration, then I get [ Xx-. ].
I'm using led-controller:flash on nokia n900 (so everything in software).
