Dear Nordic,
I have built a board using nRF51422, and I've just manage to populate it and start it up.
I'm using a modified example (peripheral_lbs), and everything seems...
Hi, I have an Adafruit Feather52 board which is preloaded with a serial DFU bootloader and the S132 Softdevice, of which I also have the merged Hex file. I would just like...
Hi,
I am designing a custom PCB using the nRF51422 chip. I have a program that I developed on the nRF51-DK. The program reads the capacitance value of a proximity sensor...
Hi All,
i need some helps. I need a device that can connect with one phone only, so i have created a whitelist wih size of 1.
During the life of device the device can...
Hello, I'm pretty sure the new BLE 5 will come out soon and it will integrate the mesh. And if mesh needs to be done at a protocol level, it must be the softdevice.
So...
