# Transports All scanner share the same basic connection args. The argument `--target` specifies **all** parameters which are required to establish a connection to the device under test. The argument to `--target` is specified as a URI. An URI consists of these components: ``` text scheme://host:port?param1=foo¶m2=bar |location | ``` The parameters support: string, int (use 0x prefix for hex values) and bool (true/false) values. The relevant transport protocol is specified in the scheme. ## isotp The can interface is specified as a host, e.g. `can0`. The following parameters are available (these are ISOTP transport settings): * `src_addr` (required): The ISOTP source address as int. * `dst_addr` (required): The ISOTP destination address as int. * `is_extended` (optional): Use extended CAN identifiers. * `is_fd` (optional): Use CAN-FD frames. * `frame_txtime` (optional): The time in milliseconds the kernel waits before sending a ISOTP consecutive frame. * `ext_address` (optional): The extended ISOTP address as int. * `rx_ext_address` (optional): The extended ISOTP rx address. * `tx_padding` (optional): Use padding in sent frames. * `rx_padding` (optional): Expect padding in received frames. * `tx_dl` (optional): CAN-FD max payload size. Example: ``` text isotp://can0?src_addr=0x6f4&dst_addr=0x654&rx_ext_address=0xf4&ext_address=0x54&is_fd=false ``` ## can-raw * `src_addr` (required): The ISOTP source address as int. * `dst_addr` (required): The ISOTP destination address as int. * `is_extended` (optional): Use extended CAN identifiers. * `is_fd` (optional): Use CAN-FD frames. Example: ``` text can-raw://can1?is_fd=true ``` ## doip The DoIP gateway address is specified in the location. * `src_addr` (required): The source address as int. * `dst_addr` (required): The destination address as int. Example: ``` text doip://169.254.100.100:6801?src_addr=0xf4&dst_addr=0x1d ``` ## tcp-lines A simple tcp based transport. UDS messages are sent linebased in ascii hex encoding. Mainly useful for testing. Example: ``` text tcp-lines://127.0.0.1:6801 ```
