In src/nrf52840/transport-config.h, and replace it with #define UART_BAUDRATE NRF_UARTE_BAUDRATE_460800.

Find the line #define UART_BAUDRATE NRF_UARTE_BAUDRATE_115200 Openthread/ot-nrf528xx and set up the build environment: git clone -recursive. To set up the Nordic nRF52840 example for use as a sniffer, clone NRF52840 DK connected to the host machine by its debugīuild and flash an NCP device to serve as the sniffer, using the ot-rcp binary output. Install Pyspinel and dependencies without extcap.īuild the sniffer Note: This guide was tested with and written for the Nordic Semiconductor.Review the Packet Sniffing Requirements.Set up the sniffer environmentīefore you begin, complete the following steps: To use the Wireshark extcap plugin for packet sniffing, refer to Packet Sniffing This guide covers how to configure Wireshark and run Pyspinel to sniff packets
