No. 1704 Data Loss wit CSW-M83 Serial RS232 to WIFI 2019-12-04

Hi,

The CSW-M83 is configured with the picture joined from ezManager.
We know this is working very well in serial mode direclty branched on computer.
We use the software Yat to spy and get back data from serial or wireless Lan from CSW-M83.
So in serial no pb the data are always correct.
In wi-fi with the CSW-M83 some data are truncated and we loose some frame.
The serial port send a frame of 23 bytes at 800Hz. The frame always begin with 0x02, then followed by datasize 0x13, then a frame counter in the third byte.
The record below is done via YAT in TCP wireless mode :

//The firs two lines are correct
02 13 83 bf fb bf fb bf eb bf f8 bf fc 81 25 bd a5 82 32 81 4f de 41
02 13 84 bf f7 bf fd bf f0 bf f8 bf fd 81 25 bd a5 82 32 81 4f 20 4f

//Here we miss some data we are not at a frame start 0x02 and the frame number pass from 84 to 91. so we loose data.
e9 d7 02 13 91 80 03 bf fa 80 02 bf f7 bf f8 81 25 bd a7 82 32 81 4e
0f 24 02 13 92 80 03 bf fc 80 04 bf f5 bf f9 81 23 bd a6 82 31 81 4e
67 42 02 13 93 80 01 bf fd 90 02 13 c1 80 01 bf fe bf fa bf f8 bf fa

Is there a buffer instead the CSW-M83 that is full and data are overriden ?
Any idea or clue on why ?

Thanks.

JP Garros.
