@ajb2k3 Yes I removed the loop because I wanted to add the restart option at the end of the code to use the low power mode basically.
So now, it restarts, reads and sends the data, and goes to sleep.

@ajb2k3 Hello, so after fiddling with it yesterday, I understood the same thing still happens. it works for longer periods, but then stops responding again and dies. This is the sketch I am using now:

@felmue Thanks for the advice.
I added a restart after every 120 seconds to save battery, and downloaded the code to the device, but then every time it restarts, it shows the UIflow logo, beeps, etc etc, until it gets to my application page. Do you have any idea why this happens?

@ajb2k3 Thanks a lot! it seems like it's working for now!

Hi everyone,

I am very new to this, so sorry if my question might be a bit too obvious.
I have made a CO2 monitor on UIFLOW using CORE Ink and a CO2 module. it shows the data on the screen and also I used REMOTE+ to read the data on my phone.
Everything works well for around 5 minutes and then Core INK freezes. I have no idea why.
Can you please help me diagnose this?
