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...

Hello,
I am having an issue with the GPS on the nRF9160. I have been developing a custom program that will switch between NB-IoT and GPS when an interrupt pin is triggered...
Hi.
I am curious to know if it is possible to use the ANT-only Softdevice with the Zephyr RTOS. The goal is to create a BT BR/EDR + BLE 5.0 + ANT+ device all on the same...
Hi,
What is the maximum frequency that i can capture on GPIO port of nRF52840 ?
I'm planning to capture a frequency of 32MHz from a sensor on GPIO pin , can I do this...
Hi,every one!
As far as i konw, the original connection interval that ios sets is about 50ms, that is a little too fast for me, so i want to change the connection interval...
Hello,
Ive got an question of my Central BLE nRF54280 Dongle. I want to read the advertising packets of Sensors with the Name "RH". Shouldnt be a big problem. But i got...
Our device is based on nRF52840 with SDK 15.0.0
The device communicates over BLE with PC application (aka client) via "uart" service.
PC (client) messages are signed using...
Hi ,
