https://devzone.nordicsemi.com/f/nordic-q-a/6836/disable-sd-for-sometimeHello devzone... My setup: nRF51422 and S110 peripheral My setup transmits IR data on reception of Bluetooth data from a central device. I have used PWM for generating IR pulses. It is configured as GPIOTE, the timer compare event toggles the pin.
