We found a problem with a client's legacy design. They use two 12 pF load capacitors for the 32 MHz crystal, which has a 4 pF capacitance. This is a somewhat unusual Abracon...
Hello DevZone,
I have a project where I currently use the AT%XPOFWARN feature, in order to turn off the modem in case the battery voltage is too low. It's used in both cellular...
We use several Nordic chips in our BLE sensors. We bond to the devices from Android, connect to update configurations, then disconnect such that the device then advertises...
Dear Nordic DevZone,
I'm encountering pairing issues with mobile devices and a nRF54 DevKit flashed with HCI over UART firmware. After initial pairing, deleting the bonding...
