Dear All,
so we have an embedded SoM running OpenWRT and I was wondering if I can make use of nrfutil even if not connecting a nRF52 via USB but via UART.
What I want...
So as far as I can make out, when I load a new application into the flash, the NRF52 will attempt to first load a secondary memory space and if successful, it will then replace...
Hi,
Right now i am using Blinky example in Peripheral section of SDK15 (S140). I would like to enable Coded PHY (BLE_GAP_PHY_CODED) instead of default setting (BLE_GAP_PHY_1MBPS...
