Blynk Bridge suspends the program

Need Help With My Project
1

Hello.
I have a program on ESP8266 with a temperature sensor and an oled display. The program was always working correctly until the bridge was added. After adding the bridge, the program freezes at random intervals.
What can be a problem?

}



// Create the MCP9808 temperature sensor object

I know you are somehow using deepSleep(), but your void loop() is the problem… and all the delay() commands… yipes… :scream:

Thank you so much for help.

I changed the program according to the instructions.
There was only one delay in the void setup {}
which is needed for the correct operation of MAX17043.
The program is still crashing.

You are trying to do a whole lot of stuff in that one single loop cycle.

Consider using a Blynk standard void loop() with just Blynk.run() and timer.run() and short BlynkTimer based one shot timeout functions for smaller code routines, giving each enough time to complete before engaging the sleep cycle with a final timed function.

I’d put a delay(2000) after your deep sleep command, to stop the code executing while deep sleep kicks-in.

I’d also put some Blynk.run() commands in your void loop. Put one after each of your blocks of code to ensure that Blynk gets enough processor cycles while all of that stuff in the loop is being executed.

You may also need a short delay - maybe 100 millis - immediately before the deep sleep command, to ensure that the Blynk.virtualWrites have completed before going to sleep.

Lastly, make sure that the link wire between GPIO16 and RST is a good connection. I’ve wasted quite a bit of time in the past with a device that seemed to lock-up, only to find that I had a dodgy contact and that was preventing it from waking up.
