LED color setting (from sketch) problems #176

Open thorathome opened 3 years ago

thorathome commented 3 years ago

Hi. I use Blynk LED widgets, blinking them on and off using a timer to show a heartbeat from my devices. 

#define HEARTBEAT_COLOR "#D3435C" // red
#define HEARTBEAT_VPIN V29
Blynk.setProperty  ( HEARTBEAT_VPIN, "label", "Working" ); // this does not work
Blynk.setProperty  ( HEARTBEAT_VPIN, "color", HEARTBEAT_COLOR ); 
Blynk.virtualWrite ( HEARTBEAT_VPIN, 150 ); // or Zero

I observe that the LED widgets do not operate consistently, often start working only when I manually set the LED color from the tile, but not always. This applies to "color", "label", and value. I see this behavior on iOS and on Android. Sometimes they work, sometimes they do not. When I put a Value Display widget in on the dame datastream, it shows the correct values. The LED stays off.

Any suggestions for me?

@thorathome Do you have a V29 data stream on the webdash in the template of this device? Which value type is it using?

thorathome commented 3 years ago

Yes, thanks, I do.

The web dash widget was initially set as a Label. I also tried setting it as a Slider. Either way, the correct values show on the web.

Suggestions?

@thorathome what's the setup of your datastream: it's min/max and type?

thorathome commented 3 years ago

It's set up as an Integer 0-255.

One thing I have noticed... I have 14 Datastreams numbered 1-4 and 6-15. I deleted number 5 after initially creating them, then added the last one numbered 15, also the same Datastream we are writing about. So we have a gap in Datastream IDs, number 5, and a last Datastream added, number 15.

I also notice that when I add any widget for Datastream 15, Integer -255, the LED widgets in the same Tile stop working on iOS. When I remove the widget for Datastream 15, the LEDs all seem to work on iOS. When I add a Value Display for Datastream 15, it works, but still causes the Android Tile to fail with the Parsing error I noted.

When I have a moment, I will create a totally new Template, Device and Tile running the same code to see if it works any better.

Hope this is helpful.

@thorathome, We had found the cause for that parsing error, looks like you had some set property call on that datastream in the wrong format. Soon it will be fixed.

Thanks for fixing this. The Blynk 2.0 System is getting more reliable day by day. I am submitting another Issue on Android LED behavior...

Thanks, all. Enjoying the power of the new Blynk server-side logic.
