Hey i'm a newbie. I'm presently working on with the sim900 with gprs shield and i wanted to use AT+FTP commands for file transfer, but when using the AT commands for FTPGET i'm gettin a error called "net error". The module when came across the AT+FTPGET=1 should return ok, +ftpget:1,1 but i'm getting the response as
ok followed by +ftpget:1,61. Can someone provide a solution for this command.
thank you
 

Hey,
did u attach your module to gprs using at+cgatt? and did u open bearer profile using at+sapbr before executing at+ftpget?
 

This is my situation.... where the problem ? DNS problem ? European GPRS/protocol standard ? Also ftp/ip pdf application of Simcom doesn't go. Regards
