Hi,
I am developing a vendor specific Mesh Model, I have already integrated the mesh model sucessfully to my network and is able to send data from each node by multiple hops. I am facing some issues from the mesh model.
1. During data transmission if the device resets, reply attack happens and that data wont be received
2. This is my config. I have done everything I can can to increase the throughput, please advise if there are any other way to increase speed to accommodate my payload size. My payload from one node is 240bytes.

3. My most vexing issue is even with 0 hops sending 240 bytes payload in a single send, I am facing a delay of 2 seconds, The time taken to start the transmission from the callback of START and to reach the callback of END of the message i am getting a delay of 2 seconds. This is too long for my implementation, kindly advice on ways to reduce it.
