Dear nRF Gurus,
I made a board with nRF8001 and PIC24F to stream some sensor data to a computer. I have also developed a simple Mac app to communicate with my board. (similar...
Hello,
I am redoing some experiments with 2 pca10001 and the ble_hrs example (with s110, s120) !
What I would like to do is that the s120 side displays the power received...
I'm designing a small board with an nRF51822. I'd like to use a 'meander' PCB antenna similar to the ones on the Evaluation Kit and 'dongle'. Is there a definitive guide ...
