FTP failure | Telit Cinterion IoT Developer Community

Trying to send files per FTP on EHS6, using the internet services (SISW) I found the following issue:

After sending the last packet and finishing transmission with "^SISW=0,0,1" I get: "^SISW: 0,0,0" and "^SISW:0,2". According to the manual should this confirm successful transmission.

But sometimes transmission failes and no or incomplete file appears on the server.

When transmission was successful, the FTP server reports "^SIS: 0,0,2100,"226 Transfer OK"" before the module sends the "^SISW:0,2" confirmation.

Does any one have experience whether this is an issue of the EHS6 or the FTP server. Customer uses FileZilla Server version 0.9.36 beta? Have I to wait in any case for the "Transfer OK" from the server (would be a problem because e.g TC63i does not provide server messages like this)? Can it be, that regardless of confirmation by "^SISW:0,2" a transmission may fail?

Unfortunately I don't have the possibility to try another FTP server in this case.

I never had such problems before (we have thousands of units in field), so Ithink it may have to do with the server version.

Thanks for your help
