Can't turn the lights on

[tamasharasztosi]

Hi! I cannot make this work. I have a esp8266 (data pin: D4) connected to ws2812b lightstrip with 32 leds. I could connect to it thought the phone app but cannot turn the lights on. The only instruction I didn't do is this because I didn't find this one: Replace avm/pgmspace.h with pgmspace.h what I set up: wifi creditials,

define NUM_PIXELS_PER_LIGHT 32

define pixelCount 32

define pixelPin D4

set #define PRINT_BUFFER_LEN 4096 in aJSON.h and this one shows as many device in the app as I write into it:

define MAX_LIGHT_HANDLERS 2

What have I missed?

Are you sure the electrical connections to the LED strip are correct, can you use it using other sketches using the same LED library (e.g., its example sketches)?

[tamasharasztosi]

I have tried the LED library's examples and it worked great with both GPIO2 and GPIO3 connection/method. And your project is also looks like working on my device because the strip goes white-red-green (on all the 50 leds) and the pairing process in the app also looks good but after that I can't control the added lightstrips (however in the serial monitor the state and stuff change after I set something in the app). Could you write down your config? How should I set NUM_PIXELS_PER_LIGHT, pixelCount,MAX_LIGHT_HANDLERS? Have I missed something? And where should I replace avm/pgmspace.h with pgmspace.h ? Thank you for your help.

Same issue here. I get the white / red / green scans indicating I've got wifi connection. My Android Philips Hue app establishes a connection, but is not switching the strip on. Serial monitor indicates communication is happening. Did you get it working tamasharasztosi?

Sadly i didnt manage to make it work so i gave it up..

@tamasharasztosi can you control your LED strip with the example files that come with the https://github.com/Makuna/NeoPixelBus library?

Last time it worked with bitbang method I think, but now I can make it work at all. Im using Wemos D1 mini board which is based on ESP-12, the data pin is connected to D4 (GPIO2).

I have the same issue. I have it working with NeoPixelBus from this example: https://www.reddit.com/r/arduino/comments/4yb6cl/wemos_d1_mini_internet_status_led/d6mmc7b/. My LED ring has 12 pixels and I have modified the code in that post to use 12 pixels and they all light up.

With regard to the ESP8266HueEmulator, when I plug my Wemos D1 mini in the USB controller I see first a red led running (2-3 times), then green led running (1 time) and finally 1 led of 12 leds stay on.

Ok guys, finally it started working with bitbang method! (only with that)

My setup:

define MAX_LIGHT_HANDLERS 2 //in LightService.h

define NUM_PIXELS_PER_LIGHT 21

define pixelCount 41

define pixelPin 2 //(D4 on wemos d1 mini)

NeoPixelBus<NeoGrbFeature, NeoEsp8266BitBang800KbpsMethod> strip(MAX_LIGHT_HANDLERS * NUM_PIXELS_PER_LIGHT, pixelPin);

Also replace avm/pgmspace.h with pgmspace.h in Arduino/aJson/aJSON.cpp

Bitbang solved it for me too! Thank you @tamasharasztosi .

Now how to get the iOS version see the same setup that I created with the Android version of the app.
