nRF8001 not working with Arduino YUN

[vincentd26]

Good morning,

I have a problem with a nRF8001 board : https://www.adafruit.com/product/1697
( bought on september 2014 from amazon.fr )
I never could make the sample sketch "echo demo " to work
The problem is that the display on the console stay on : Adafruit Bluefruit Low Energy nRF8001 Print echo demo
No other line is printed, no error displayed

I reset the Arduino YUN board, checked the wires, the soldering, changed the breadboard but nothing worked : still same result.
Checked the voltages : nothing on RDY, 3.2V on 3V pin
I made the connexion to the Arduino through WIFI and with USB : same problem

Thank you for your feedback on this matter.

The Arduino side of the Yun is the same as the Leonardo. You have to follow the wiring instructions for Leonardo:

Posting my problem on sunday morning, I didn't expect an answer by the sunday afternoon...
But it came, and the right one !!!
Shame on me to not have better read the documentation of the YUN board....
Thank you very much for your presence by the side of your users !!

I replaced the following pinouts for my Yun and as a UART (with Echo) it worked great! However using it with Adafruit_BLEFirmata to control does not... :-( Using Arduino 158Beta)

Changes Made: based on: http://arduino.cc/en/Reference/SPI
nRF8001 -> UNO -> YUN:
SCK -> 13 -> ICSP-3
MISO -> 12 -> ICSP-1
MOSI -> 11 -> ICSP-4

I then had to modify the boards.h file to even get the "StandardFirmata" to compile. But still no luck. I ran across this which seems helpful but so far no luck.

Any ideas?

Thanks! ~LegoZebra

Bummer.. Looks like a known issue, despite Firmata 2.3.2 being updated to support Leonardo (BANNED), BLE_Firmata is not... See: viewtopic.php?f=22&t=58293

If can be resolved, that'd be cool!

I'll give the engineering team a nudge.
