Hi Naeem,

I no longer use the GPIOTE interrupt for TWI read action now.

Thus, I will close this ticket.

Thanks for your help!

Hi Terry,

Can you show your implementation?

May be I can try to reproduce what you are getting.

Hi Naeem,

I used P0.19 for the GPIOTE.

GPIOTE interrupt is no problem if I do not do the TWI read action inside the GPIOTE event handler.

I think the problem is GPIOTE with TWI issue.

Hi,

Which pins you are using? Can you check there are no conflicts.

If you are using a DK, then the pin P0.09, and P0.10 are used for the NFCT.

Maybe you can change the pins and check again.
