@Stef_Weicks ok can you copy the readtime function from my old code to this new one ? And see if it works ?
no don´t work
does not connect
omg i think i found the failure…
ha … it was
i must not switch off bluetooth > with the funktion btStop (); … i deleted it and now it works!!!
but I really don´t know what bluetooth has to do with the whole thing?!
@Stef_Weicks ahah cool
thank you so much for helping with my stupid problem 
…
I hope this did not make you even more headache than you had from your parties
@Stef_Weicks aha no problem it’s actually an issue that should be raised. True that before the time is set, it goes to the btstop(). Anyway. Happy that we could make it before I take off.
i am happy too! but you know why this happens? i think it doesn´t matter where i put in btStop (); tried it now in setup or after setting clock …
and you are programming while sitting at the airport? …haha…
why not … you have to wait for the plane
@Stef_Weicks it will require more investigation. Maybe it is due to something else while compiling
ok … i understand!
… are you married or have a girlfriend? because i think you’re really often on the road. … that doesn’t matter her ? 
@Stef_Weicks I am single for now. I was married but never had a girlfriend …
ah ok ! my girlfriend got something from our project and wanted to know that … sorry for this private question 
i tried a little bit to deactivate the bluetooth as well … i had a little success if i am putting btStart() at the beginning from setup()
and did the deactivation btStop() additionally with wifi_off .
it connects than … but the serial out shows always " could not create buffersize"… so i putted it after the pin settings and than it doesn´t connect anymore.
i also tired now deep sleep … it´s working but I donnt know how exactly the integrated RTC is? do you know is it possible to set a specific time or is there only the timer function?
@Stef_Weicks ahah no problem. I don’t have any issue with that. I am a proud geek nerd gay ;).
I guess some more investigation about the btstop() needs to be done. The best place will be to post an issue on github/dépressif.
For deep sleep you have two choices either waking up using the internal clock or using an external trigger.
This external trigger could be your RTC but it will need an alarm functionality. I know there are RTC with this capability. You need to look for your model.
ah … ok … i will do
maybe i will buy an other RTC clock for this purpose… !thanks for the tip! today i want to try the timer of the deep sleep to see how exactly this is
an other question … i have in the sd-card-mode (but only in sd-cad mode) a problem with screen-flickering of two pins… i tried it also with other pins which were not taken and got the same results… i checked the wires and so on … but in artnetwifi there is no problem with this pins!!
maybe you know how to handle this… in daytime its not the problem because of the light around … but at night its annoying, especially if i dimm the panel, than there are very bright light flashes of the flickes.
i posted a video so you can see better.

@Stef_Weicks do you have the same issue with the older version of the code ?
Do you have the issue with every animation ?
I remember having this issue two at some point. I need to remember what I did.
i have had this problem since the beginning … but i thought i could solve it with rewiring i didnt know this is only in sd-mode … because in artnetwifi it works without issue. Therefore i changed the pins pin1 from 2 to 15 and pin4 from 12 to 25 (i also tried the other pins of the controller which were not taken, which i think work worse)… the flickers are mostly at the evening very annoying because than i switch the brightness of the screen darker.
could it eventually be because of the wifi ?search./connecting/disconnecting. because than i think i see more flickers. but also if the controller is connected to the wifi or the controller is not connected there are such flickers which you can see in my video from above (but are not as much as while the dis/connecting processes).
@Stef_Weicks I think you’re right because the reading of the SD happens at the same time as the check of the wifi which may have an impact when the two collide.
you could add this
Serial.println(“SD-Card”);
wifistatus=false;
…
else
{
myFile.seek(0);
}
wifistatus=true;
it will interrupt the check while reading the SD card almost i would say
hm yes I would say now it is better … while connecting disconnecting there are still flickers but its not as bad as before… still testing
i did it also here
if(MatrixTime==0){
Serial.println(“on”);
wifistatus=false;
matrix->print (datestring);
wifistatus=true;
because the clock was still flickering… think this is so also better
