Hello,
i'm developing a custom board with nRF5340 (WLCSP package) that is very constrained in terms of space for a Bluetooth application. I looked on DevZone and i found...
I first tried nrfjprog which didn't work, but I know that's being retired so that wasn't entirely surprising. After that I moved on to testing 'nrfutil', specifically the...
I am building a BLE audio product that is based on the nRF5340. The application is largely based on the nrf5340_audio ncs example application, but I am modifying the the application...
