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!
I have BMD-350 -A-R and I want to program this by using SWD pins (SWCLK, SWDIO, GND Detect, and VTG) of Nrf52Dk . I make all the connections properly but for some reason...
Hi,
for evaluating purposes I'm trying to send quite big amount of data (100 kB) via socket interface. Sending proceeds fine until approximately 60 kB is transmitted. After...
Hi,
when powering up the nRF52840 PDK its interface MCU LED is blinking fast and the board is not recognized. I've tried to update its firmware by putting the board in bootloader...
On some android phones we have observed that if we try to scan using nRFToolbox for nRF51/ nRF52 controller advertising with UART they do not show up in the scan list. But...
Hello,
I am developing a wireless sensing device using the nRF24L01+ module and I'm planning to use a u.FL connector in my design. I can't seem to find any manufacturer...
