Hi. I'm quite new to nRF programming. I successfuly solved how to compile/link/flash the software onto nRF52 DK using just a simple editor (Notepad++), the ARM toolchain and...
Wondering if there are any example/reference implementations of a bootloader for the nRF51822 that support Device Firmware Update over both UART and BLE? We've got the BLE...
Hi,
I have met problem when apply dfu of nrf52810.
I used dfu sample of 52810 from devzone link: https://devzone.nordicsemi.com/f/nordic-q-a/28471/about-ota-for-nrf52810...
I met a big issue when implement the voltage level switch. I used nRF52832's SPI to communicate with an ECG sensor which has 1.8V SPI. The issue is that, 3.3V signal from...
Having just got the DFU functionality working I got the task of trying to add NFC functionality to the application. The code side was not a problem since I got a c and h file...

Hi there,
I'm putting together a PoC board for a demo - in this case size matters and I've had to make some compromises for the sake of speed (which have increased footprint...
Hi,
After setting up constant carrier, how can one determine that it is working. With no modulation the receiver can't determine anything, can it?
thanks
Hi,
SPI use with SDK14.2.0 leads to very high power consumption (around 400 µA) on nRF52832 (QFAA). The same piece of code running with SDK12.3.0 has much lower power consumption...
