I’m testing BG95-M3 (BG95M3LAR02A03_01.011.01.011) and I get this sequence:
Really 1024 bytes is the correct length for “1k.bin” .
Why first call returns error code 550 = “Requested action not taken: file unavailable”
Is it always required a directory read command, before AT+QFTPSIZE ?
Before querying , pls check your current path with the below cmd
Thank you for your support. It seems this problem to be related my specific FTP server ! I have changed test setup from my WEB provider to a local FileZilla server and the problem disappeared. If the file i need to get the size is located in login directory ("/"), do I need anyway to execute QFTPCWD and QFTPPWD sequence ? I thought “3.4 File Operation” session log was only an example and not a mandatory sequence !
