Nr52 Arduino Core / NRF Propriatery Wireless

[Kiko Lobo]

Hi I am planning a new product and doing some research, it is going to be an educational product, my question is if there is support in the arduino core to use the propriatery NRF protocol? Or supported by third party libraries. 

i am planning also to talk with older NRF2401+ devices, so I also want to know if this is possible.

lastly... If you have the option of PCB antena, wire antenna or chip antenna, which one would you pick for best Rx performance?

Hi,

I am not familiar with arduino, but google may be of help in specific. 

For non-arduino you may find this useful:

The most important for any antenna design is that it is optimized (tuned) in the final plastic casing placed in a realistic location. In such case any antenna design can perform equally well. So typically it is more a question of space available (size) and cost.

Best regards.
