Hello,
In my quest of working with pstorage_raw.c I found an annoying situation when I tried to clear small portions (as I thought by using raw I would have full control...
Hello!
I have based myself on the ble_app_uart example, taken out the UART bit, and all that remains is the bluetooth functionality.
I have also implemented SPI communication...
hi guys, :)
I used SDK 6.1.0., Softdevice version is S110_nRF51822_7.0.0.
I compiled the template project. (in the "C:\Keil_v5\ARM\Device\Nordic\nrf51822\Board\nrf6310...
I want to use the UART to get and send data to another MCU on ble_app_beacon of SDK 8.1.0.
But after I add the UART function to the project, the UART can't work.
Can the...
Thanks for the SDK 8.1.1 fix. Please make it available also as a .zip in developer.nordicsemi.com/.../
Currently the fix cannot be used with a GCC toolchain as it is only...
