Hello,
on EG912Y I use the multplexer (CMUX) to have multiple connections at the same time (one TCP, one UDP, and one FTP).
Each connection works on its own cmux channel.
I have a problem with the ftp connection ( the ftp connection is used for upload a file to a FTP server) when this connection in used in parallel with a tcp connection.
The problem happens when the data of the file is uploaded and the escape +++ sequence in send to the modem (on the owner channel).
I don’t recive a response from the modem.
If I resend the file without parallel connection TCP,everything works correctly.
what can I check ?
