https://devzone.nordicsemi.com/f/nordic-q-a/6184/softdevice-serialization-rpc-spi-exampleI 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 code available for using the Spi interface?en-USTelligent Community 13Tue, 24 Mar 2015 10:16:22 GMThttps://devzone.nordicsemi.com/thread/21656?ContentTypeID=1Tue, 24 Mar 2015 10:16:22 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1b960737-07a2-4ea2-9f6d-8ff65008b46aStian R&#248;ed Hafskjold<p>You can find a list of the available examples here for both the connectivity board and the application board: <a href="http://developer.nordicsemi.com/nRF51_SDK/nRF51_SDK_v7.x.x/doc/7.2.0/s110/html/a00042.html#serialization_software">developer.nordicsemi.com/.../a00042.html</a></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/21655?ContentTypeID=1Mon, 23 Mar 2015 06:06:53 GMT137ad170-7792-4731-bb38-c0d22fbe4515:9d5a3188-2f55-4b32-963a-81a3a415b0bbKrzysztof Chruscinski<p>Hi,</p> <p>there are couple of physical transport layers available for serialization: SPI (6 wires - additional request,ready lines), SPI (5 wires - additional request line), UART, reliable UART (HCI transport) and low power UART (to be used only with STM MCU as application).
