Hi,
I'm using a lightly modified copy of the Multilink central S120 example code. When I get to ble_stack_init() the first thing it does is SOFTDEVICE_HANDLER_INIT(NRF_CLOCK_LFCLKSRC_XTAL_20_PPM...
I found the Ble Serialization here and the example sourcecode within the sdk sources.
It uses uart with 38.400 Baud and hardware handshake (Rtc/Cts).
Is there also example...
Hi,
Looking at the manuals for the S110 and S120 soft devices, I don't see mention of the bootloader in the S120 manual. Does S120 support bootloaders?
