Hello
Cool ! so maybe I should publish it here in the community if you think it’s stable enough
I am not a specialist of that library because I do not use 16x16 matrices. But you can try this one
wich is to be used a lot by the people here
and you have MatrixTilesExample.ino
then when that’s is working it will be pretty straight forward.

Now I am working again with the artnet wifi code and would like to assign a static IP. I set the IP
IPAddress local_ip(192,168, 1, 103);
IPAddress gateway_ip(192,168, 1, 1);
IPAddress subnet_ip(255, 255, 255, 0);
and assigned it in the void setup () like this …
WiFi.begin (“3WebCube568B”, “dcF52eC5”);
WiFi.config(local_ip, gateway_ip, subnet_ip);
the router connects to the IP and is connected … but if i start the transmission … it doesn´t work…
do you know what the problem could be?.. with my esp8266 i did it always like this … and it worked fine 
@Stef_Weicks hello stupid question first. have you changed your mapping in jinx ?
If yes then we will need to have some debug output in the program.
Yves
no … i have set the same ip address in jinx … double checked all… did you set a static ip on your pannel?
@Stef_Weicks I have never used static ip.
Let do some test on my configuration and see if it works or not. Just got home give me couple of minutes
no problem! … i have time 
router : espressif 192.168.1.103
and jinx: 192.168.1.103
@Stef_Weicks hello just go to you router stop and start the WiFi.
When I tried first I had the same issue but in my router I could not see my esp.
certainly because it creates a pair MAC address/dynamic ip (this is why you esp always had the same IP address)
So I just stop and restarted it and it worked I have tried two different ip adresses.
Btw I put the line WiFi.config before WiFi.connect
@Yves_BAZIN hm… first test … didn´t work…
…i rebooted my router … router says …
Static-30:AE:A3:18:36:6A 30:AE:A3:18:36:6A 192.168.1.103 Statisch
jinx is running … if i delete the lines all works well
@Stef_Weicks ‘if i delete the lines all works well’ you mean when it goes dynamic ip ?
Have you exchanged the two lines ?
on the serial monitor … it does not connect … the router says it is connected…
yes i meant if its dynamic ip it worked
yes i have exchanged them…
@Stef_Weicks reboot the esp?
i rebooted with no improvements
maybe … there is something in my code … i don´t see

@Stef_Weicks try with another IP address
Or just reboot sometimes issue of connectivity with esp32 to the wifi
@Stef_Weicks I meant reboot the esp once I had to do it 5 times before it connected correctly 
ah ok … i tried it now with an other wifi-router … same result…
i will try to reboot a few times…moment
@Stef_Weicks wait couple of second when the 6 become 1 before rebooting
