init parameters

None

action parameters

padding, like: 'padding':0x55

If set, then all ISO-TP/UDS messages will be padded to 8 bytes with chosen byte value.

range, like: 'range':[1,0x901]

Should be set. Pings will be generated for following ranges of arbitration ID. In this example there will be 0x900 frames in queue to ping.

services,

like:

'services':[
    {'service':0x01, 'sub':0x0d},
    {'service':0x2f, 'sub':0x03, 'data':[0x22,0x22]}
]

Used only in UDS mode. Here we describe which UDS services and subcommand should be sent. sub can be:

Int value:  'sub':0x0d           - check for one sub-command
Str value:  'sub':'0x01-0x03'    - scan for range of sub commands
List value: 'sub':[0x01, 0x03]   - scan for chosen sub commands

user commands
