I use SPWF01SC.11to send data to server (about 6KB every 4 minutes).I split data to 2 packages (3KB each package) then send to server by TCP Socket.But sometime 1 package is lost.

Can anyone help me to solve this problem?My mail is

Hi,

since a long time I tried with different STM32Fx and STM32Lx and others, and I never experienced a behavior like this.

I always use also PC scripts (bash, pyton, etc), without any problem.

Module is able to catch bytes up to 921600 baudrate, with and without flow control.

I can only assume that module is not really receiving 5 bytes when your printf sends out 5 bytes. Check your STM32 application (before), and use an oscilloscope (also) to be sure that STM32 is really sending 5 bytes.

There is an application note, with related firmware package running on

STM32F0DISCOVERY

. If you want, you can use that package as reference ( http://www.st.com/web/en/catalog/tools/PF260583 )
