Possible to detect a double press vs a single press for media buttons via bluetooth?

[Frank O]

I'm trying to use Tasker to bring up Voice Commands via bluetooth
headset button (via my car's media controls). I can get Tasker to
detect a single button push, but not a long press or double press. My
car is a 2011 Subaru Forester and it really only has forward/back
buttons available to send via bluetooth.. so I'd like to figure some
sort of method out to get my media buttons working for single presses
(as it does now, without Tasker) and either a double press or long
press to bring up voice commands. I think long press will not work, as
the Subaru interface seems to drop the button command if I send it too
long (I tried switching my single press command to use Long Press and
it didn't work at all).

Ideally I'd like:
Single forward -> next song
Single back -> prev song

Double forward -> voice commands


I sort of had an idea with setting variables, but I can't really time
out a variable set can I? i.e. set variable to 1, if no button press
within 2 seconds set variable back to 0.

Any ideas? Thanks! :)

I would like to be able to detect long/double press as well.
Any way of doing that?

Hi V,

Thanks for that, unfortunately it did not work. The phone got very
confused between single and double pressing. I double pressed and the
OneClick flash kept flashing every second or two.

Little trick is there :) You have to make two "oneclicks" with a short pause in between. Tasker grabs media button clicks, detects how long the pause was and if it less then threshold says "that was double-click" and vice versa.

You have to run some experiments with my suggestion and tune it for Your environment.

P.S. I didn't use it myself, because sometimes delay from one click without Tasker's grabbing is too long. Maybe the cause in the hard load of CPU with other tasks (continuous video recording, Tasker's tasks, etc.). So, if I'll put it through Tasker it'll be much more, even with 10-th priority of profiles. This DoubleClick was a next  brain-twister, only.

What about run it on QUAD-core platform? LOL
