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 guys,
My question is really general: How do I reduce the TX Power of an nrf51822 BLE beacon?
The situation is the following:
1. I ordered this device: https://www...
We have a problem on our test system: it cannot communicate with our DUT on ATT level after 30 seconds.
Our DUT consists of a NRF52840 with SDK 16.0.0 and softdevice S113...
I have an issue with the NRF beacon code combining with the NRF rtc code.
I want to set up a bluetooth advertisement with an incrementing value. Therefore, want a timer...
Hello,
