Error code from nrf_drv_gpiote_in_init

[JIYEON]

Hello,

In my project, nrf_drv_gpiote_in_init is used 3 times.

• battery measure
• sleep trigger by motion sensor
• wake-up trigger by motion sensor

After 3rd call of nrf_drv_gpiote_in_init, NRFX_ERROR_NO_MEM(0x04) was returned.

GPIOTE channel might not be available.

Is there a way to use more GPIOTE channel?

I changed NRFX_GPIOTE_CONFIG_NUM_OF_LOW_POWER_EVENTS from 0 to 8.

It works now:)
