hi ,
i am using nrf52832 dev kit , using which i am capturing accelerometer data from LIS3DSH for an RTC interrupt of 2 minutes, i.e., for every 2 minutes it should capture accelerometer data,
first interrupt it is working fine with capturing data , but for second time it is going for a breakpoint condition, not able to understand , can anyone please help
