Hello,
I have custom board with nRF52832, and I want to have possibility to DFU over UART.
I tested example bootloader (nRF5_SDK_11.0.0\examples\dfu\bootloader\pca10040...
I am using nrf51 SDK v.12.1.
And I found NRF_LOG_INFO("BLINKY START\n");
where can I find this log?
Is this different from SEEGER_WriteString or something?
Hi
We are using "gcc compiler" to compiler our programs. To download our programs we use "nRFgo Studio" app.
From the above image, when we load SDK into the device...
