Random hang of MKR GSM 1400

[Freshrik]

Hi!

I see some related topics but none without GSM communication running. I am having issues with the MKR GSM 1400 hanging at random times just as other have. Some have related te issue to a hang in a while loop within communication. I howerver, only use pin change interrupts, a timer and toggle an LED. I am yet to set up communication. There seems to be an issue even without the GSM-communication.

Thank you for any input!

hi @Freshrik which is the timer library that you are using?
