multiple data on single node not received

[pragnesh036]

Hello There,
When I try to send multiple data frem to my single node.
From issue:- [https://github.com//issues/751]
I have solved the problem to receive multiple downlinks at the same node successfully.
After the downlink comes we execute some ms oration
But After the first downlink operation, the second downlink is not received and the code generates the "rx TimeOut" Error.
If I will do not perform any operation it works fine.
Is there any way to sync this?

Please guide me to solve this problem.
