First time here? Check out the Tour!
i have added pwm into proximity profile example and now i am able to make beep using buzzer with pwm library.Now i want to make some sort of Tune instead of beep.
Can any one help!....Thanks.
Hi, I'm working on a design with nRF52832 + chip antenna. I'd like to add a PI network to be able to tune the antenna before production.

Hi, i am going to tune my PCB meander antenna by soldering center conductor of semi-rigid coax cable directly on to the coplaner wave-guide trace and outer conductor on to the ground. Can somebody here please suggest me the semi-rigid ... (more)
Hi, i am designing a board using balun in it. Also, i am going to use meander antenna of nordic dongle(reference image is attached). As i can see, there is no RF coplaner waveguide strip but there are RF ... (more)
I've developed a board with NRF8001 module mounted on it. Antenna on the board is much longer than in reference designs, so I can change the length. I also can add shunt capacitor/inductor. The problem is that ... (more)
We decided to add NFC functionality to our nRF52 open source sensor beacon design, RuuviTag: http://ruuvi.com
I would like to ask your opinion about the antenna design, because Nordic hasn't published (correct me if wrong) any ... (more)
I am designing a board based on the SoC nRF51822. Since this is a homemade project I do not have lab equipment so I can not measure antenna impedance and therefore tune it. I found this design note from ... (more)
