BG77 udp data to retrieve are missing

Hello,

I use a BG77 with Uart connection. I am able to connect eMT network, able to open socket, send data. I receive notification that I have X bytes to receive (48 exactly). But when I ask data to be send from modem to host controller, I am only able to receive the 4 first bytes. I checked with digital analyzer if I missed something (salae logic) but I see nothing more than on my OS … Were are my data ? And why I cant retrieve them all.
Please find at following, what I send and what I receive from open socket to end of get bytes :

Hello,

I checked with an oscillo and I dont see any more data on the line. So that means I dont loose data. Any idea on what I must do for retrieve my 48 bytes of data now ?

Thanks in advance
