nRF Sniffer for Bluetooth LE is a useful tool for debugging and learning about Bluetooth Low Energy applications.
This project is a patch to the original nRF Sniffer for nRF51 boards with slow UART.
The original original nRF Sniffer v2.0.0 set the UART to 1000000 baud. This high baudrate is not supported by some development boards such as the BLE400.
The firmware sniffer_pca10028_uart_115200.hex sets the UART baudrate to 115200 bps and the extcap Wireshark capture script has been modified to recognize this baudrate.
