set_record(true) on G15 does not work from autostarted script

Hi experts,

still amazed of CHDK even after 2 years using it. Respect!

I have just a small issue:
By powering on my G15 with the play back button or the power button the lua command
set_record(true) from an autostarted script does not switch the camera in record mode.
On my SX260 and my IXUS 85S it works fine.

The following script never prints something:
set_record(1)
while not get_mode() do
  sleep(100)
end
print (get_mode())

Any idea?

It would help speeding up my startup sequence at the field with my copter...

Greetings,
Harald

Is the camera's USB port connected to something when you're trying to run your script?
If not, try using click("shoot_half") instead of set_record(1). This is supposed to simulate half-pressing the shutter button for a moment. I'm not sure why the original method doesn't work on the g15.
Can you tell us the CHDK version you're using (exact filename of the .zip file)?

Try adding a short sleep( ) at the start of the script.

Something like :
Code: [Select]
sleep(1000)
set_record(1)
while not get_mode() do
  sleep(100)
end
print (get_mode())

Thank you so much srsa_4c and waterwingz for the fast answer.
The behaviour is the same with:
g15-100e-1.3.0-4029-full.zip
g15-100e-1.4.0-3963-full.zip
g15-100e-1.4.0-4153-full.zip

But both press("shoot_half") and the wait(1000) did the trick!
With and without 11 pin USB+A/V combo cable from VP Systems.

Have a nice day,
Harald

Did you mean to say "Either press("shoot_half") or the wait(1000) did the trick!" ?

So sorry, it is indeed misleading.
I meant not both together but I can take either one of the solutions...
