Hello,
I'm having difficulty getting the GPIO set up in a way that behaves predictably on the nRF9160 DK. As far as I understand it, the nRF52840 is what controls the GPIO...
Hi All! My question is that while using coded PHY is it possible to enable the ACK? In case no ACK receives then retransmission of the same packet to the receiver. Thanks...
I am trying to measure the frequency of the square wave on the ARDUINO_6_PIN on the NRF52840 Dev Kit. It seems like it works well until the square wave goes above 2MHz. Is...
Hi,
I see that in the latest SDK 17.1.0 there seems to be no example for regular UART but only for LPUART.
That made me wonder if there is any advantage in any scenario...
I have an external flash
