The GND pin on the Bluefruit LE SPI Friend should be connected to the GND pin on the UNO.

Re: Arduino connection
Missed your reply - yes , w/ the Uno it´s just fine.
Should I try other pins on the Mega board?

Re: Arduino connection
Since the 8, 7 and 4 seem OK, what other options on the Mega?

Re: Arduino connection
It should just work on the Mega with the same pins. As it did in my test setup.
It seems like there is possibly something wrong with your Mega. If you have a second Mega, can try that. Otherwise, would need to investigate and determine what might be wrong with that Mega. Try another SPI device and see if the SPI pins are OK. For the other pins (8, 7, 4), could use LEDs and buttons to verify basic digital in/out is working as expected.

Re: Arduino connection
I only have a LE UART module, can that also be connected as a SPI?
PS tested the Mega, the other pins work at least w/ the Blink sketch.

The Bluefruit LE UART Friend:
https://www.adafruit.com/product/2479
only supports serial UART. It does not support SPI.

Re: Arduino connection
Thanks for your help - as of now, I don´t seem to get any further
