Hi,

I am developing a project with NRF51822 and i want to block signals in one direction. Is it possible ? And if it is possible, how can i do this ?

Thanks !

Thanks for advice Turbo J, but i have already tried it. I used a aluminum foil behind the pcb and nothing changed. And also tried Faraday cage and again nothing changed.
