Problem with receiver frame when skip AARQ

Hi

I am trying to connect meter for PUSH communication. For this i skip AARQ request. Loaded association using xml file. But during read pushSetUp i am getting error of invalid HDLC frame.

Here are logs :

<-7E A0 07 03 81 93 F0 AE 7E

I have found that senderFrame in GXDLMSSettings.java is increased but receiverFrame is still have its previous value. Which is giving error.
Eg. First time Sender Frame is 16 and receiver frame is 14.
After first request Sender Frame change to 50 but receiver frame is still 14. Which calculate expected sender frame is 48. But i receive 82 which is correct. So expected sender frame should be 82.

Note: Here frame values are in decimal.

Please help me to get out of this problem.
