I have a Wismo 228 with version L10-00g.WISMO228. Modem is attaching to cellular network and an IP number is generated using the command
AT+CGACT. I am trying to use AT WIP commands and they all return ERROR as result. I am trying to open a socket connection to a server, but
I don’t seem to find the way to do it without the WIP commands.
Can this AT WIP commands be activated by another AT command? Do I have to update Wismo’s firmware? If that’s so, anyone would care to
explain how?..and where I can obtain the firwmare.
Any help is greatly appreciated,
