Hi all,

I am new in here and also quite new with programming. The issue I have is the following:
I start a simple rotational measurement and try to write the measured data (rpm) to pushingbox and further to my google sheet (all 10 revs.). I have a display, showing me the right rpm values and it works . Also a small testing porgram worked to write data to my google sheet, but with static values.

So here it goes:
after 10 revolutions, a program is started to write the measure and calculated rpm value to my sheet, and it fails. I have to restart my ESP32. Right when I hit "WiFiClient client;" it goes off and shows an error... I can not post the error message right now sorry... But maybe you guys have an idea what's wrong with my code... Already tried to disable interrupts when writing function is called with "noInterrupts()"....

Using ESP32 Heltec WiFI Lora 32 v2 and Arduino IDE...

Many thanks!

At first look, your password is too short ...
Googling "WiFi minimum password length" will reveal you that minimum password length is 8 characters and maximum 64 !

oh well I changed it for posting it here... the original one has 10 characters.

sorry :/

No one has any idea...?
Still having this issue...

Perhaps it helps if you can copy-paste the error message here?
