Hi,
I'm using the nRF52832 with SDK version 17.0.1.
I've noticed that when the device wakes up from NFC and remains in proximity to the NFC field, it sometimes experiences...
Greetings! I've applied all the optimizations in the books but I cannot get our application to be ~50% of the available flash memory on the NRF52832, currently it is precisely...
Hello,
I'm working on a project that involves using an NRF52832. Basically, I want to collect data, send it over bluetooth, and then have the device enter system_off mode...
I got started with bluetooth learning. But it's too hard to understand ble protocol. Do I have to learn BLE protocol even If my purpose is only ble communication with simple...
Hi,
Could someone help me about the following questions?
Q1: What are the connection parameters set by the Android app nRF Connect? Can I change them?
Q2: How can...
I have a bit of a strange problem.
I am designing a signal Gazell signal repeater.
It listens in host mode then sets itself as a device to pass the data along.
However...
Is it possible to put the nRF52 into recieve only mode (say through direct test mode) so that the input impedance can be measured using a VNA? Is the input impedance of the...
When I initialize PPI after timer1 has been initialized I get a fatal error (and reset).
Code:

Hello,
we were measuring sleep modes and it consumes around 1.3uA which is correct.
But when we needed to be woken up on edge we found out it consumes extra 8uA! Are you...
