Hi,
Firstly a warning I'm a noob in this area.
I'm seeing some strange events consistently returned from the nRF8001 over SPI. I have an example of the SPI traffic below which shows everything working fine until a point. The strange thing is that if I put a printf("delay") in my aci loop when lib_aci_event_get(&aci_state, &aci_data) == FALSE it works fine and I get no spurious unexpected events.
Any advice would be most welcome at this point as I have been looking into this issue for a number of days now.
