Stability issues connection to Blynk

Firmware
1

Good afternoon ScruffR, I did the procedure that you indicated and RETURNED TO RUN !!!
Thank you for your help, I am very glad to work again.

I would like to take the opportunity to take another question.

While the Photon is connected in Blynk server keep the Particle Server off and when needed, I trigger via a virtual button. There would be a problem to keep the two servers connected at the same time.
I can not maintain stable hardware using Blynk, sometimes when I enter the APP Blynk the photon restart the Hardware.
You have any suggestions to make the most stable software using the Photon and Blynk?

For now thatā€™s it.

One more time thank you for your help.

Hugo.

@enghugo, posting your code or a cut down version which still causes the problem would be helpful.

Good Peekay 123 days, Iā€™ll be putting down a part of every code of 3 devices that are interconnected by Blynk.

That is, if someone can give a help as best stability between Blynk and Particle I thank you very much.

Thank you, Hugo.

@enghugo, there is a lot here! I noticed that you have reconnect code for WiFi and Blynk but not for Particle cloud (ie Particle.connect()). I suggest that you wrap the Particle.publish() in your timer callbacks with if (Particle.connected()) so it doenā€™t publish while the cloud is not connected.

I am also not sure about call Blynk.notify() from a Software Timer. I suggest you replace the Alerta timer in the Main Photon with a non-blocking timer in loop(). Try moving any network-specific code (Particle.publish(), Blynk.notify() etc. out of the Software Timers and into loop() to see if that makes a difference. As much as they are great to have, Software Timers can behave oddly, especially with threading enabled.

Good afternoon peekay123,
Put on routine condition if (Particle.connected ()).
I disabled the Threand function;
Letā€™s see how will be the systemā€™s stability.

What Iā€™ve been seeing is that the problem appears when Iā€™m long without entering the APP. When Iā€™ll use the APP the hardware resets, losing CONNECTION with all servers.

What Iā€™ve been seeing is that as took updates to the Photon and the Blynk, the hardware is more stable.

Thank you for the good tips.

Hugo.

Blynk doesnā€™t like delays, any delay after calling ā€˜blynkā€™ will cause it to block connections to both particle and blynk, and usually endlessly reboot device. Or just drop connections alot.
