I can't get the nRF8001 echo demo to work on a Teensy 3.5. I have tried to pin map the 3.2 to the 3.5 and uno that are discussed in length here on the forums, but have had no luck. The serial monitor displays "Adafruit Bluefruit Low Energy nRF8001 Print echo demo", but never shows "Advertising starting"; so I removed (!serial) from the code, but that didn't help.
SCLK - SCK0 on D13
MISO - MISO0 on D12
MOSI - MOSI0 on D11
REQ - CS0 on D10 - I've tried this on D6 as well
RDY - D2
ACT - NA
RST - CS0 on D9
GND
5V
Thank you for any help you can provide!
