Hello,
I know that FTP feature is not enabled on some of the modules. And FTP feature can only be enabled by a password protection AT command. But this is the case when using wip library. Maybe yours related to an other issue.

What does this error CME 842 stands for? Did you check documantation?

Hi,

thank in advance for your help, in documentation CME error 842, is destination host unreachable( whether host unreachable, Network unreachable, response timeout). This error appears after several seconds after a connection request. This let me believe that’s a response timeout error.

I have tried connections to others port:

at+wipcreate=2,1,“212.3.190.77”,8080
+CME ERROR: 842

but result is the same.
this is a random trasparent proxy located in my country that works in this moment.(from my pc)

last thing i tried
at+wipping=“212.3.190.77”
OK

+WIPPING: 1,0,0

and response is a timeout

it seems work only on port 80

Maybe your gsm operator allows your sim card to access only through port 80. Operator may block other ports. Or you may be need to register with a different apn name which has access to other ports.
i think you can ask your operator for help. And ask your distributor too. They know which problems people face with and their solutions.

Yes, u are in right !!
I found an apn list on the operator website, and i’ve found one with full functionality ! all works well now ping and all kind of connections !

Thx for ur suggestion !

Best regards
