Hi,
I have just bought an nRFGo Motherboard (nRF6310) to develop for the nRF24LE1 (nRF2722). I was able to run some example code on the chip like toggling a pin. Next I...
Hello,
I have an application based on SDK 11 and Softdevice v2.0.0. Also there is a legacy bootloader from SDK 11 for performing DFU.
I am wondering whether it is possible...
When I run the UART app nRF5_SDK_12.3.0_d7731ad\examples\peripheral\uart in debug mode, the disassembly window opens, and I seem to get stuck on the second instruction. Step...
I am using a nRF52 and I have to measure two voltages:
the first continuously
when a command is received, the second voltage have to be measured and then...
Hi,
I flashed my nRF52840-PDK with UART/Serial Port Emulation over BLE program. Everything seems to be ok and I can connect with board via Android application. Next I would...
