Hi,
I am trying to set an nrf52840 pdk (with SDK14 and s140_nrf52840_5.0.0-2.alpha) as peripheral and central at the same time and another nrf52840 pdk just as a peripheral...
Hi,
I play with pca10040 and the light-switch example from SDK for Mesh v1.0.1. Everything works but I wonder why the advertising signals are not seen by nRF-Connect Scan...
Dear Developer Zone,
I am using nRF51822 with softdevice.
Small question about device reset : To reset the chip, do I need to do NVIC_SystemReset() or sd_nvic_SystemReset...
