I will start doing a custom PCB (1.3cm diameter) with a nordic BLE, any recommendations about the components needed and design?. I need to use mbed programing tools, any experience about it?

Hi,
Have a look at this blog describing the recommended design guidelines for nRF52, nRF51. The essential components for the nRF51/52 chip can be found there, with a diameter of 1.3 cm you will want to use the WCLSP package as well as a chip antenna. The rest depends on your application.
Best regards,
Øyvind
Thank you, is there a reference allium design for WCLSP?, i could not found it. greetings
nvm i found them thank you.
which chip antenna should I use?
Antennas are so application specific that I cannot point you to a specific antenna and say that this will work for your custom design. What you will have to do is to evaluate the size and space that you have available and see which antennas meet your specification.
If you have a look at chip antenna manufacturers site (Johanson, Murata, etc), you can look at the size specification and how they should be implemented, to see if they match your requirements. Any 2.4 GHz antenna would do.
