Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Hi, is it now possible to flash (via DFU OTA) a nRF51X without the nRF Dongle, but with a generic BLE dongle on Windows 10 ? Thank you for your answers.
Hello,
I am using Nordic's iOS library to perform DFU in our app to upgrade firmware on some BLE devices. Before the DFU, the app scans it as "Paradevice", but reads it as...
Hi,

Hi
in pcb designing of the nrf52832 we use two oscillators one is 32 MHz and another one is 32 kHz.
can't we use both 32 kHz instead of one 32 MHz for saving power consumption...
Hi,
I can't seem to find an example for receiving an update about restored value of CCCD when a bonded peer reconnects. I'm using SDK14.
NUS and HRS examples which use...
