Not a question, but a big thank you to Nordic Tech Support (Kristin) who reviewed our nRF24 design several times until we got it right :)
Implementing the recommendations...
Hi,
I am creating the first prototype for my BLE product and for now I used the suggested layout from the datasheet, but I am kind suspicious of that layout it seems very...
I follow the example, as below
