Hi,
I am using nRF52832 with NUS and buttonless DFU running well next to each other (SDK13). Instead of the standard way to jump to the bootloader (writing a 0x01 to the...
We have a device running SDK 11, without a crystal. It was using:
#define NRF_CLOCK_LFCLKSRC {.source = NRF_CLOCK_LF_SRC_RC, \
.rc_ctiv = 16,
.rc_temp_ctiv = 2}
