SYNOPSIS¶

isotpsend [options] <CAN interface>

OPTIONS¶

-s <can_id>

(source can_id. Use 8 digits for extended IDs)

-d <can_id>

(destination can_id. Use 8 digits for extended IDs)

-x <addr>[:<rxaddr>]

(extended addressing / opt. separate rxaddr)

-p [tx]:[rx]

(set and enable tx/rx padding bytes)

-P <mode>

(check rx padding for (l)ength (c)ontent (a)ll)

-t <time ns>

(frame transmit time (N_As) in nanosecs) (*)

-f <time ns>

(ignore FC and force local tx stmin value in nanosecs)

-D <len>

(send a fixed PDU with len bytes - no STDIN data)

-l <num>

(send num PDUs - use 'i' for infinite loop)

-g <usecs>

(wait given usecs before sending a PDU)

-b

(block until the PDU transmission is completed)

-S

(SF broadcast mode - for functional addressing)

-C

(CF broadcast mode - no wait for flow controls)

-L <mtu>:<tx_dl>:<tx_flags>

(link layer options for CAN FD)
