Using fds write in GPIOTE interrupt handler

[ref]

Hi,

Is it possible to write/read the flash memory, from within the interrupt handler of GPIO? I used an push button connected to a GPIO to wake up the ble chip, then read flash memory, add its counter by one and update it.  All done within the handler of GPIOTE interrupt. The problem is that the chip crashes when the I push the button. I'm not sure what I'm doing wrong here. Any help would be appreciated.

Thanks,

Hi,

What are you interrupt priorities? You cannot make FDS calls from a too high interrupt priority, as described in this post.

You're right. That was the issue. I used a flag and do the read/write in the main(). 

Thanks for the help.
