Hi Nordic Support Team,
I'm currently experimenting with Channel Sounding using a couple of nRF54L15 boards.
I am trying to obtain raw I and Q samples so that I may analyze...
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...
I am struggling with the correct value to use for DFU_APP_DATA_RESERVED in the bootloader. My application uses the Device Manager and has one block allocated for to pstorage...
My app is generating hardfualts. Based on this post I looked at memory location SP + 0x14, which points to the address that generated the fault.

Hi.
Is there a (lazy) (dummy) comfortable way to make an nRF518 chip (in my case, nRF51822) communicate with the built-in bluetooth adapter of a laptop with windows 7 or...
Hi,
I am trying to connect a GPS through UART to nRF52 and get the reading and write it to the serial USB of my PC. I am using app_uart_init() and app_uart_close(). My idea...
Hi, I would like to handle in the twi_event_handler the case when the p_event->type == NRF_DRV_TWI_EVT_EVT_DATA_NACK differently and not treat it as an internal error.
