Hello,
I am trying to follow the tutorial SDK UART coexistence example , but it seems like the last step cannot be completed. As you can see, that .hex file does not exist...
I am working on a low power peripheral project (similar to the Nordic blePeripheral/uart example). I'm going to be using an nRF52805 with SDK 17 and s112. I found the Apple...
Dear all,
I have tried my best to find answers in questions posted previously but I still have a few questions that I would like to clear up. I will keep it concise. Thank...
I want to configure the UART1 (not the UART0), and I want to know if there have some examples that introducing the UART configuration by directing accessing the register....
Does Nordic have programming for the nRF52840 that enables both 802.15.4 and BLE, so the board can both become part of an 802.15.4 network and pair with a mobile device like...
Hi All,
i played with the /examples/dfu/secure_bootloader/pca10056_S140_ble_debug.
The application works fine so far.
I do have the following questions.
Is it...
Hi,
I am running into some problems with libuarte. I have two nRF52840-DKs talking to each other over UART. My setup is not ordinary however. The hardware configuration...
Hello -
We are developing a product for the nRF52840 using SDK v17.0.2 and FreeRTOS. Our application uses the RTC configured by FreeRTOS to implement a System ON sleep...
