we received new party of wavecom product Fastract supreme 20. On these producs, we can not connect ftp server while we can still connect on previous products. Previous products and new party products have same firmware, we installed same application file on both. Strangly new ones can not connect ftp with wip_FTPCreateOpts function. It returns NULL.
I searched a little and found a topic which says it may be about Internet Plugin disabled with new modules. I executed AT+WCFM=5 and it returns +WCFM: 00000070,0 on new modules. On the other hand, this command returns +WCFM: 00000031,0 on previous modems. But i couldnt understand what this response come to mean. Does it mean that internet plugin disabled on these modules or what else can cause this annoying problem?
