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,
I'm investigating on a problem we found in our system. It seems not related to our custom pcb or firmware, you can replicate it with the following setup.
Setup...
I will need to store some data (and edit it again later) and fetch it later in the nrf51dk even after turning it off and back on.
How can I store such persistent data in...
Some situations like heavy ble activity causes the nrf52832 to restart without hitting breakpoints in the NVIC_SystemReset.
Assuming there aren't any hardware issues, is...
Can I use J-Link EDU for nRF52840-PDK , nRF Connect , please?
Is it sufficient?
What the J-Link PRO provides for nRF52840-PDK, nRF Connect that the J-Link EDU does not?
Question preamble
I am writing a bluetooth application where two nRF5 devices will be in a master / slave configuration. However, I want to be able to flick a physical...
Hi.
I have an application that needs a low security encryption. Therefore I want to use "Just works" encryption. The pairing process is assumed to be in a "safe" place...
I am having a strange problem. After I flash the program to the NRF52 and do a reset (does not matter whether it is a soft reset or pin reset) the system (DK and my own board...
