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

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

Since the 8, 7 and 4 seem OK, what other options on the Mega?

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.

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:

only supports serial UART. It does not support SPI.

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