我尝试通过 python 向 Vector CANoe 发送消息。首先我已经配置 CAPL 节点发送循环消息,它可以工作 (id 0x100)。然后我想通过 python 发送消息-我的代码在,但我得到“Not Acknowledge error,dominant error flag”1。你知道可能是什么问题吗?我已经在网络硬件配置中配置
import can
import time
from can.inteces.vector import canlib
from datetime import datetime
bus = canlib.VectorBus(channel=0, can_filters=None, poll_interval=0.01,
receive_own_messages=False, bitrate=500000, rx_queue_size=16384,
app_name='CANoe', serial=None, fd=False, data_bitrate=None,
jw_abr=2, tseg1_abr=6, tseg2_abr=3, sjw_dbr=2, tseg1_dbr=6, tseg2_dbr=3)
messageSend = can.Message(arbitration_id=0x200, data=b'\x07\x31\x01\x60\x60\x01\x00\x01',channel=0,
is_fd=False, check=True)
bus.send(messageSend, timeout=0.1)
print(messageSend)
received_message = bus.recv()
received_message.timestamp
print(f'Received: {datetime.fromtimestamp(received_message.timestamp)}')`
