Electron did not publish

Hi,

I’m using an Electron to publish some sensor measures, the problem is, sometimes sends and sometimes did not send info to particle.

Does anybody knows why?

thank’s

Seeing what code it’s running would definitely help.
But it mentions the last reset being because of power management. Could the battery be running low?

Like @Moors7 said, please share your code.
Are you getting the same results with the Electron plugged in through USB?

Hi,

Below you can see the code, I hope you like it :slight_smile:

Yes the publishing fails with and without battery connected. The USB is allways on.

Thank’s for your help

You have 20 seconds of blocking code in Setup().
That can’t help the situation.

Hi Rftop

I did not understand, so sorry!!!

thank’s for your help

HI,

The problem is the script has a failure but I don’t know where or why?

I put a publish after every reading to see where the script stops publishing…I found where, I commented these lines, but stops before…a nightmare.

Is it possible to debug the script? that’s critical to find where is the problem…I’m desperated

Thank’s

The battery always need to be plugged in, otherwise it can lose power when transmitting data, due to current peaks. That’s might explain the power errors.

What improvements have you made since (the delays for example?)

Hi #Moors7

The battery has already connected and full power. See below the code, but all stops after leaf reading

There is any way to debug the process? I tryied to do the same process with serial and it works correctly.

Thank’s for you help

a new strange thing:
sometines the info comes from the name of the machine “Electron_XXX” and sometimes comes from a long ID

I’m a newbie, but here is what I would try:

  • Move all the Sensor Readings to loop()
  • Remove any Sleep functions, until you get the code working
  • Remove ALL the individual Publish Events for EACH Sensor, because you have a publishString at the end of the code anyway.

The loop() will constantly read all the sensors and update the variables.
Perform the Publish Event for publishString in an IF STATEMENT that checks for your pre-determined publish delay.
Right now you CODE “attempts” to publish way too often.

Hi Rftop

At last I think I found the problem. Particle did not accept a long Json (I don’t know why) I divided the json in two jsons, and putting 4000 delay between and now it works.

How long was your string?

I had the same issue. The Electron can go to sleep before the publish completes. It is a simple fix, just add Particle.process() after you last publish, before the sleep command. This makes it wait until the publish has finished.

Cheers,
David Barrett

This should have been taken care of with 0.6.0 (probably 0.5.3 already) on Electrons and 0.7.0 should do for WiFi devices too.

Hi DavidBarrett

I’ll try do this, thank you very much

Best
