I am using Argon in a solar powered application. Using System Mode MANUAL. It enables WiFi periodically, do one publish and disable it. If I publish every 10 minutes, it works fine. If I increase the time to say 60 minutes, Particle publishes do not go through. Following is the section of relevant c…

Without seeing your definitions, setup() or knowing your os version - I would try changing the Particle.publish() statement: [image] sunder: if (succ) Particle.publish(eventName,mystring1); You might try using the following and examine the bool result: if (succ) { bool pubSuccess; pubS…

Thanks Rob. Will add code to retry if the first publish fails. There seems to be something unique about MANUAL mode where if the interval > 10minutes, the success rate drops drastically and consistently.

[image] sunder: Will add code to retry if the first publish fails. I'm sorry. I wasn't being clear in my last post. This if statement: [image] robc: if (! pubSuccess) { // get here if event publish did not work } is where you would find out, immediately, the publish failed - n…

Instead of all these while() loops you should rather use the dedicated functions waitFor() and waitUntil(). Also your i < (30000/BLINK_INTERVAL) check will not give you 30 seconds but an arbitrary time as the runtime for Particle.process() is non-deterministic. You will call it 30000 times and howe…

Thanks @robc for your detailed comments. Just to clarify, every delay() implicitly calls the Particle.process()? Also, how often do I need to call Particle_process() in the MANUAL mode to have a reliable connection?

Thanks @ScruffRfor your comments. if using waitFor() with a timeout, does it ensure that the Particle.process() is called periodically while it’s waiting? For millis(): Do I need to take into account the millis overflow/wrap-around when calculating time difference? Is there any example code?

@sunder [image] sunder: if using waitFor() with a timeout, does it ensure that the Particle.process() is called periodically while it’s waiting? Yes [image] sunder: For millis(): Do I need to take into account the millis overflow/wrap-around when calculating time difference? Is there an…

[image] sunder: Just to clarify, every delay() implicitly calls the Particle.process()? No. In general terms, a delay() statement will invoke Particle.process() when a background cumulative counter of delay ms = 1000ms. Example: with no previous delay() statements called - If I call delay(800…

[image] robc: If I call delay(800) four times, by the end of that sequence Particle.process() will have been invoked twice. Oops! That is not right, sorry. The answer to the above should be three calls of Particle.process(). Another example: If I call delay(800) six times, by the end of that …

[image] robc: to publish_count++; delay(2000); Particle.process(); // New line - last statement within loop() } As stated above I'd rather use this for(uint32_t _ms = millis(); millis() - _ms < 2000; Particle.process()); for a 2 second delay when maximum cloud performance is w…
