Wireless Controller keeps disconneting

[LAKY911]

Hi, thank you for this library. I am using it for a car controller in my bachelor thesis. I have used Dualshock 2 wired controller but I would like to switch to wireless controller. I have bought a chinese clone from Aliexpress but sadly I can't get it working neither via bitbang nor HW SPI. Bitbang doesn't work at all. HW SPI works, but the controller keeps disconnecting every 3-5 seconds. Do you please have any clue what might be wrong?

Thank you very much Best Regards

Maybe to add - the controller disconnets for 1 second and then connects again for the 3-5 seconds. During this connected time it works flawlessly. And it is being recognised as Dual Shock.

First of all make sure that the wiring is solid. Then please try some of the suggestions from this post and thread.

[LAKY911]

Hi, thank you for your help. I can confirm that the wiring is solid and correct. Although my controller works good with the Psx library as in the post you mentioned, I wasn't able to get it working via editing the parameters as you described.

So it still remains the same: HW SPI disconnects every 3-5 seconds, recognised as dualshock. Bitbang nothing, the controller isn't recognised at all. I noticed one thing, on the receiver there are two LEDs, one is PWR LED, this one is simply on. And a second one is RX, this one usually blinks 1 second on, 1 second off - when disconnected from the controller, turned on when connected. But when I upload the bitbang sketch, it somehow blinks completely randomly.

I will try adding the external pullups 1k Ohm resistors on the CMD and DATA lines as you suggested and will let you know.

Thanks for your help.

Are you using 1k pull-ups?

[LAKY911]

Hi! Yes, I am using 1k pull up resistors on the DATA and ATT line. Is that correct? I just tried the bitbang example with DUMP_COMMS. You can see that the controller (probably) gets detected, but cannot enter config mode.

Again, thank you for your help!

I don't think the pull-up on ATT is necessary, but it won't hurt anyway. I'd also add one on CMD. In any case, this also all depends on how you did the 5V <-> 3.3V level-shifting.

[LAKY911]

Hi, thanks for your help. Seems like the problem was low voltage. In the manual I got was recommended voltage 3.3V which was not working. I have changed the voltage to 5V now and everything works fine. It looks like I have a new desing of the receiver so maybe they changed the circuit desing to 5V now? I don't know. Anyway, thank you so much for this library. Best wishes, L

[SukkoPera]

That doesn't make much sense, actually. Controllers were designed to work at 3.6V and 3.3V is usually fine. I don't recommend powering them at 5V, despite what maaaaaany crappy tutorials out there say.
