Is it possible to support iso15765-2 message over neovi interface?

Here is the example from python_ics:

https://github.com/intrepidcs/python_ics/blob/2201cba0344e923aa6bc2472d5e61c3661b63658/examples/iso15765_example.py#L50

Iso15765 Fuctions

def transmit_iso15765_msg(device, netid=ics.NETID_HSCAN, is_canfd=False): number_of_bytes = 64 msg = ics.CmISO157652TxMessage() msg.id = 0x7E0 msg.vs_netid = netid msg.num_bytes = number_of_bytes msg.padding = 0xAA

Flow Control

msg.fc_id = 0x7E8
msg.fc_id_mask = 0xFFF
msg.flowControlExtendedAddress = 0xFE
msg.fs_timeout = 0x10 # ms
msg.fs_wait = 0x3000 # ms
msg.blockSize = 0
msg.stMin = 0
# CmISO157652TxMessage.flags bitfield union isn't implemented as of 2.12, we need to do it manually.
msg.flags = 0
# paddingEnable
msg.flags |= (1 << 5)
# CANFD: Enable + BRS
if is_canfd:
    msg.flags |= (1 << 6) | (1 << 7)
# tx_dl
msg.flags |= (8 << 23)
# Data
msg.data = [x for x in range(number_of_bytes)]

# Transmit the message
print("Transmitting iso15765 message on {}...".format(dev_name(device)))
ics.iso15765_transmit_message(device, netid, msg, 3000)
# Wait for the messages to be transmitted, this can be calculated a lot better but works here.
time.sleep((((number_of_bytes/8)*msg.fs_timeout)/1000.0)+0.5)
#print_message(msg)
print("Transmitted iso15765 message on {}.".format(dev_name(device)))

Closing since ISO-TP support is handled by python-can-isotp, so there's nothing actionable here. Driver-level support can be handled there.

Please feel free to comment if you feel otherwise.
