https://devzone.nordicsemi.com/f/nordic-q-a/808/nrf51822-dk-keil-mdk-armHello, Does Keil&#39;s Lite/Evaluation MDK-ARM tool chain version suffice for development work on nRF51 devices? Please advise! I have seen questions about using GCC and Eclipse in place of this tool chain. Is it because of licensing issues?
