Thanks for the reply!
Have you read the rather long thread on the topic. http://forum.rfduino.com/index.php?topic=30.msg3181#msg3181
I have read the above thread, a few times now. It is long, so I still am not sure I caught everything.
The subroutines of Sam Decrock do work for me. I can control the LEDs with a preset routine. I also have had success with the FastLED library at http://fastled.io/
, though it is unnecessary.
However, I'd like to send data bout which routine to run via BLE. But, upon BL receiving data, the routine goes awry and the RFduino resets, or colors are thrown off, etc. I am being informed that this is due to not being able to handle interrupts while using the WS2812B's, and thus I will have difficulty sending data while a pattern is running (which I would ideally like to have a looping LED-routine, which I can change to another looping routine as desired).
AVRISP is not used to program RFduino or Simblee. How are you able to program the RFduino or Simblee now?
Disregard this... I am not using a "programmer" after all. Rookie misunderstanding. Just ctrl+U.
