How to Read Specific OBIS Codes in 48 Association without getAssociationView() ?

Hi,

I want to read only these two OBIS codes in the 48 association:

This is my input:

sampleclient.main([
'main.py',
'-S', self.S,
'-c', '48',
'-a', 'High',
'-P', self.HLS,
'-C', 'AuthenticationEncryption',
'-T', '54333435',
'-A', self.A,
'-B', self.B,
'-D', self.HLSHX,
'-g', '1.0.0.2.0.255:2; 0.0.96.1.0.255:2'
])

Currently, it takes 20 to 24 seconds to execute getAssociationView(). How can I read the required OBIS codes directly without using getAssociationView()?

my code

reader = GXDLMSReader(settings.client, settings.media, settings.trace, settings.invocationCounter)
settings.media.open()
if settings.readObjects:
read = False

try:
reader.initializeConnection()
except Exception as ex:
msgbox.showwarning("Error", str(ex))

if reader:
reader.close()
finally:
pass

if settings.outputFile and os.path.exists(settings.outputFile):
try:
c = GXDLMSObjectCollection.load(settings.outputFile)
settings.client.objects.extend(c)
if settings.client.objects:
read = True
except Exception:
read = False
if not read:
reader.getAssociationView()
for k, v in settings.readObjects:
obj = settings.client.objects.findByLN(ObjectType.NONE, k)
if obj is None:
raise Exception("Unknown logical name:" + k)
if k == "1.0.0.2.0.255" :
val = reader.read(obj, v)
print_to_log("firmware :",val)
if k == "0.0.96.1.0.255":
val = reader.read(obj, v)
print_to_log("Serial No.:",val)
RTC = GXDLMSClock("0.0.1.0.0.255")
rtc_val = reader.read(RTC, 2)
rtc_str = str(rtc_val)
