Unable to blink virtual LED

[ebolisa]

Hi, I assisted the webinar yesterday on the new version and later on tried a simple test: blink of a virtual LED. However, the led didn't blink (on my iOS), but if I used a label widget in place of the LED widget, I did receive 0s and 1s. Am I doing this wrong or is it a bug related to the LED widget?

define BLYNK_TEMPLATE_ID "TMP"

define BLYNK_DEVICE_NAME "Demo"

define BLYNK_FIRMWARE_VERSION "0.1.0"

define BLYNK_PRINT Serial

//#define BLYNK_DEBUG

define APP_DEBUG

include "BlynkEdgent.h"

WidgetLED led1(V1);

void blinkLedWidget() { if (led1.getValue()) { led1.off(); Serial.println("LED on V1: off"); } else { led1.on(); Serial.println("LED on V1: on"); } }

void setup() { Serial.begin(115200); delay(100);

BlynkEdgent.begin(); timer.setInterval(1000L, blinkLedWidget); }

void loop() { BlynkEdgent.run(); }

Seems like iOS specific LED issue. We'll check.

I did receive 0s and 1s

@doom369 Are we removing the 0-255 LED range?

[doom369]

@eepetrash I think it should depend on the DS min/max settings. So maybe LED example is not valid for blynk 2.0. @alexkipar how you did it on your side?

[alexkipar]

@doom369 same on my side as on ios, as led is the only widget I don't know how to apply to DS model.

@ebolisa you can send 0 and 255 (set them as min/max of DS) and it will work for now

Actually, I did try it before posting. Same results:

// V1 LED Widget is blinking void blinkLedWidget() { if (led1.getValue()) { //led1.off(); led1.setValue(0); Serial.println("LED on V1: off"); } else { //led1.on(); led1.setValue(255); Serial.println("LED on V1: on"); } }

@ebolisa please make sure DataStream assigned to the widget has 0-255 min/max values. @vshymanskyy firmware should send 255 for led1.on(). Is that a firmware bug?

@boom369

@ebolisa please make sure DataStream assigned to the widget has 0-255 min/max values.

Not sure I'm following you. No such option with that widget on iOS. I can only select the color. Unless, I'm missing some here.

Ok, Got it!! Changed to V5 and worked!!

[alexkipar]

@ebolisa it should be connected with your data streams, have you checked them on web dashboard?

[doom369]

@ebolisa in the new version, values are always truncated to the min/max of the datastream. So if you send 1000 into the V1 with max = 100, it will be cast to 100.

Yes, Blynk 2.0 has has assigned datatypes to virtual pins. We just cannot use any pins as 1.0.

@ebolisa correct. From one side - it complicates the setup. From the other side it gives more flexibility, especially when you have a fleet of similar devices.
