l2ping not responding even working PS4 Dualshock Controller (bluetooth connected)

[bopnrgi]

Good morning all,
I have a PS4 bluetooth wireless controller. I have successfully connected it to the onboard bluetooth module of my raspberry pi 4.
It is functional and I can play SNES :)

The command shows that I am well connected

root@retropie:/home/pi# hcitool con
Connections:
	> ACL 98:B6:E9:BF:37:42 handle 11 state 1 lm MASTER AUTH ENCRYPT

However, I cannot ping my controller. I would like to put it in SLAVE mode, which obviously greatly improves performance.

root@retropie:/home/pi l2ping 98:B6:E9:BF:37:42
Ping: 98:B6:E9:BF:37:42 from DC:A6:32:6F:D8:D9 (data size 44) ...
no response from 98:B6:E9:BF:37:42: id 0
no response from 98:B6:E9:BF:37:42: id 1
no response from 98:B6:E9:BF:37:42: id 2
no response from 98:B6:E9:BF:37:42: id 3

I have read the thread https://retropie.org.uk/forum/post/59910
I understood the process and I want to do the same. I disabled the wifi by configuring the /boot/config.txt file. The wifi is correctly disabled.

I suppose that's a bluetooth driver problem or ACL ... But don't find a way.

Help would be highly appreciated to tell me which direction to look for.

Thanks
Clement

@bopnrgi Not sure if the said topic is still relevant today or how much latency difference is between the 2 connecting modes.

On my system (Pi4, PS4 Dualshock controller) things looks a bit different:

hcitool con
Connections:
	> ACL DC:0C:2D:86:41:F6 handle 12 state 1 lm SLAVE AUTH ENCRYPT

pi@retropie $ sudo l2ping DC:0C:2D:86:41:F6
Ping: DC:0C:2D:86:41:F6 from DC:A6:32:04:CC:76 (data size 44) ...

Thank you for your reply.

I see that your gamepad is in "slave" mode, while mine is in master. According to the subject this changes quite a bit.

But what I don't understand is why l2ping is not working on my retropie installation. Do you have an idea ?

No, I'm not familiar with it. How did you pair the controller ? Did you pair it manually or with the RetroPie Bluetooth configuration ?
