Hi,
I have been trying to study how to implement support for over-the-air (OTA) updates in my current S110-based project. But I'm already stuck in the very beginning. How...
I am using softdevice and RTX at the same time.
RTX is using RTC1, softdevice is using RTC0, so no problem there.
But sd_softdevice_enable require a clock source as one...
Hi,
I have problem with nRF51 antenna orientation. I used nRF51 developement kit (mKIT) board and I had problem with communication if I just change a little inorientation...
