Problem when using dynamic declaration of PS4BT on Arduino

[Oygron]

Hi,

I'm using your PS4BT library for robotics, and it's very great !

Now I'm trying to make a program that allows to switch from hard pairing to soft pairing without uploading a new software. To do this, I need to read a value (digital pin set to 1 or 0) before the creation of PS4BT to know if the "pair" parameter is to set to 1 or 0, thus creating the PS4BT object in the setup() function.

To keep the global knowledge of PS4, I declare a global pointer,

PS4BT* pPS4;

and then do a

pPS4 = new PS4BT(&Btd,pair);

in the setup() function, and then use pPS4->getButtonClick(...).

But when I do this, the remote controller pairs with the Arduino (hard or soft depending on the switch) and immediatly lose the connexion. If I stay with plain object declared as global for PS4BT, I need to change the pairing mode in the source code, but then the connexion works perfectly.

Do you have an idea of why this does not work ?

Thanks in advance

You need to (unfortunately) use a static instance.
This is something I wish to change at some point.

(sorry for the double answer)
Thanks for your answer.
Is there a way to delay the choice of the pairing mode ? Or to change the pairing mode while the program is still running ?

That, is Kristen's department, actually... Kristen?

Yes simply call:

PS4.pair();

When you want to pair with the PS4 controller.

Btw my name is Kristian ;)

Lol, i always seem to mis-spell it.

[Oygron]

That's it, thanks a lot Kristian !

You are welcome :)

@Oygron it turns out that this might have been cause by a missing atexit() function in Arduino - see arduino/Arduino@1bbcb2f and arduino/Arduino#2229.
Could you please try to compile the Arduino IDE from source and see if this issue is fixed?

Hi,

I could not test with sources of the Arduino project because of a conflict
with OpenJDK. But I tested with the nightly build, and the problem is still
there.

Thanks anyway for still takin care of it!

Closing this issue, as one can just pair with devices calling the pair() function.
