M95-R data sending problem

I’m using M95-R module in transparent mode with TCPIP protocol. There is no problem in sending data, but sometimes this data is received piecemeal by the server.

Sending Data to the Module with Usart: “Quectel M95-R Module”
Data Received into Server: “Quactel M9” a few x100 ms after “5-R Module”

Note: This problem does not occur when using the M95 module. I’m using the same AT Config set for both.

During your debugging, does the exception module continue to have such exception problems no matter how way you try?
M95 supports flow control. At present, MY preliminary judgment may be caused by flow control
Please replace to a better network environment for debugging and try again

The problem was solved by updating the firmware for the module.
