Problem with wifi connection after program update

Hello .
It has been 2 days since the orca I do the update of my program on a photon.
It does connect more to the cloud (green LED flashing slowly).
My system works no longer.

orca? I assume that’s a typo, not that you’re dealing with killer whales :wink:

What do you mean by “program update”? Did you upgrade to a new system version, or are you talking about new application software (your program)? I think we will need to see your code to diagnose the problem.

Yes it is my application software.
I currently have 5 photons with 5 diferent application software. They are all in firmwar 0.6.0.
On Tuesday I brought some improvement to my programs. I have to download in OTA. The 5 system does not work anymore blinking green.
All functionality cordially from 2 years.

I updated the library Blynk.

Just to be sure, is it blinking green or breathing green?
Could you try safe mode to see if that works?


yes is breathing green .
I test safe mode tomorrow (I am not at home).


Next time, try to explain the issue as accurately as possible, since breathing indicates a different situation than blinking. Breathing green indicates the cloud connection is lost, most likely due to blocking code. In the process of:
Code works -> make changes -> code no longer works, it’s often a good idea to check what you’ve changed and whether or not that could be the culprit. You’re most likely blocking the cloud connection for too long, though it’s impossible to tell without seeing code.

I use this code for debug.
I have the same problem .
I think there is a problem with the Blynk library

Thank you for your support

Could you try Safe Mode, and flashing Tinker or Blink An LED?
