Welcome in the forum, Dimitris!
The PSoC 4 BLE is quite more versatile regarding the internally available hardware components in addition to the BLE radio.
The PRoC is (more or less) just the radio and a very few components.
I would suggest you to: Download and install the CY8CKIT-042-BLE Kit Setup files
Then you have access to the example files and while your kit is on the way, you can go through the differences.
Hello Bob, thanks for the quick reply!
Ok, I see. For sure I will check out the examples, plus the nice videos that you have. Can't wait to receive my kit :)
