Hello, i have a custom board with lot of CRC ERRORS the same code, of course, works on the PDK. The spectrum transmission seems the same of the PDK.
Is it possible that...
Hi Team,
We are using the UARTE(UARTE1) module with DMA for our application with nRF52840 board, for that we are using the " libuarte " example project. For testing purpose...
Is there an example that shows the "Nordic way" of "continuous" conversions using DMA? I think a timer and PPI are needed to generate a conversion task for each timer compare...
Hello, guys!
We are using nRF52840 SoC together with the 15.3.0 version of SDK.
In our project, we basically want to combine BLE_NUS services together with the ability...
Hello!
