The following sections contain sample code for inspiration on how to use Kvaser Python kvrlib.
Connect to your remote device¶
Use the discovery functions to scan and connect to a remote device. Our remote device has serial number 16 and is already connected to the same network as our computer:
from canlib import kvrlib
SERIAL_NO = 10545
print("kvrlib version: %s" % kvrlib.getVersion())
print("Connecting to device with serial number %s" % SERIAL_NO)
addressList = kvrlib.kvrDiscovery.getDefaultAddresses(kvrlib.kvrAddressTypeFlag_BROADCAST)
print("Looking for device using addresses: %s" % addressList)
discovery = kvrlib.kvrDiscovery()
discovery.setAddresses(addressList)
deviceInfos = discovery.getResults()
print("Scanning result:\n%s" % deviceInfos)
# Connect to device with correct SERIAL_NO
for deviceInfo in deviceInfos:
if deviceInfo.ser_no == SERIAL_NO:
deviceInfo.connect()
print('\nConnecting to the following device:')
print('---------------------------------------------')
print(deviceInfo)
discovery.storeDevices(deviceInfos)
break;
discovery.close()
This results in the following:
kvrlib version: 2070
