Hi mourad,
I checked again and I have exactly that version of the RBL shield and had that working on the FRDM KL25Z. I also have the Adafruit nRF8001 breakout board working on the Nucleo boards with a similar library. I just tried this setup out tonight. It seems to work but you might need to press reset on the RBL Shield or the Nucleo to get it working reliably. I think the reset was one thing changed in the version 2.1 Shield.
The SPI connection on the RBL shield is the 6 pin female header J11 in the middle of the underside of the board. I used long wires to connect that to the SPI connections on the ARDUINO headerJ3 of the RBL shield. There are two extra connections to take care of BLE_RDY (D8) and BLE_REQ (D9) they are connected when you plug the shield onto the Nucleo. Maybe the code below will help you change the RBL example to match your board.
// The SPI construct, REQN and RDYN IO construct should be modified manually // It depend on the board you are using and the REQN&RDYN configuration on BLE Shield // config for Nucleo 401RE SPI spi(PA_7, PA_6, PA_5); DigitalInOut BLE_RDY(PA_9); // D8 DigitalInOut BLE_REQ(PC_7); // D9
