@Stef_Weicks hello
Apparently we exceed th elenght of you discussion thread :slight_smile:
How did you set up your Blynk for BLE mine does not work

(Stef Weicks) #2

Ha omg … yes i thought my handy app is crazy… before i couldn’t write back to you

Unfortunately I had to leave the pc because my girlfriend was grumpy
She said I’m just sitting on the pc instead of doing something with her :smiley: haha

Maybe would be better we write over an messenger?
Are you on Hangouts ?

(Stef Weicks) #3

There is an example on blynk for esp32. You need two libraries
Did you install the lib on Arduino?

(Yves BAZIN) #4

@Stef_Weicks yes I did it work on WiFi but not by

(Stef Weicks) #5

#define BLYNK_PRINT Serial
/*
#define BLYNK_USE_DIRECT_CONNECT
#include <BlynkSimpleEsp32_BLE.h>
#include <BLEDevice.h>
#include <BLEServer.h>

(Stef Weicks) #6

I read that there could be a problem /conflict with the library and the espressif files

(Stef Weicks) #7

I did an update of my idf and it worked

(Yves BAZIN) #8

Oki I will do so

(Yves BAZIN) #9

@Stef_Weicks btw U prefer blink via WiFi or ble ?

(Stef Weicks) #10

I like BLE because the radiation is much less than wifi.
But i think the connection works better with wifi because the developers say ble is in beta on blynk

So you could deside

(Yves BAZIN) #11

@Stef_Weicks are u on iOS or Android ?

(Stef Weicks) #12

Did you get Ble to work with your controller?

(Yves BAZIN) #13

@Stef_Weicks no :wink: it’s like my phone does not want to connect to my board

(Stef Weicks) #14

No there is a trick to get it … switch off the Bluetooth connection on your phone wait a few seconds and try it again … you can also try play stop switch pressing a few times on the right upper side of blynk and/or do the left upper switch one time should do it. And still wait … mine was running than

(Yves BAZIN) #15

@Stef_Weicks it’s like the app does not see the phone witch is really strange because my ble scab sees it

(Stef Weicks) #16

Replaced the first fastled.show by
FastLEDshowESP322();
And the second one by
FastLEDshowESP32();

tried also FastLEDshowESP322(); on the second one which worked little bit better -> this result: http://drive.google.com - IMG_2749 (http://convert-video-online.com).mp4

but with FastLED.show(); it was much better

(Yves BAZIN) #17

You have the same issue on WiFi and on SD ?

(Stef Weicks) #18

i can´t really say its so much better than with FastLED.show(); … there are already sometimes flashes in there.
between switching not connected to connected i already get sometimes a white flash for about 3 seconds.

i could try an other wifi router … i think the connection with my iphonewifi is not as good…and therefore this problem appears …

(Yves BAZIN) #19

@Stef_Weicks it’s not your router it’s the fact that we ask in contineous if the WiFi is connected or not. That provokes interruption what ever the core apparently.

(Stef Weicks) #20

so i tried my wifirouter with standart g . the animation is running much-much-smoother! and i got no flashes anymore on wifi… couldn´t be there a problem with the speed of image delivery (ping ) or so… i read something in an forum anywhere about this
