I have a custom nRF52832 device acting as a peripheral and a central. Acting as a central device it reads the device information from a nRF52832 peripheral device. Now I want...
Hi
We've some trouble with the UART (not UARTE) of the nRF52840. We use a baudrate of 38400. Because of HW limitations and power constrains, we do either have flow control...
Hello,
I am trying to test using NFC pairing with the nRF52840, but I am having trouble connecting to the device with the built-in android NFC Pairing prompt without the...
Came across a weird anomaly the other day when doing some temperature testing. One of our boards came out of it not running code and the reset line on the 52840 was stuck...
Hi,
I am trying to do geolocation using the NB-IoT chip on the nRF9160 DK. Therefore, I need the PCI and RSRP from multiple nearby base stations.
After enabling the radio...
