Hello Matt,
thanks.
It is Vodafone network NB1, region Greece but the apn is the same for all Europe. CREG is 0,5.
AT+KCARRIERCFG=0. On the Sierra site it says the HL7802 is Vodafone compatible and there is no special carrier setting for Vodafone.
The behavior is weird.
We managed to accomplish ftp changing the procedure as below ,
AT&K3
OK
AT+KSLEEP=2
OK
AT+CMEE=1
OK
AT+CGDCONT=1,“IP”,“ep.inetd.gdsp”
OK
AT+KPATTERN=“9”
OK
AT+KCNXCFG=1,“GPRS”,“ep.inetd.gdsp”
OK
AT+KCNXPROFILE=1
OK
AT+CGATT=1
OK
AT+KFTPCFG=1,“5.172.194.30”,“ftp”,“password”,21,1,0,0
+KFTPCFG: 1
OK
AT+KCNXUP=1
OK
+KCNX_IND: 1,1,0
AT+KFTPCNX=1
OK
+KFTP_IND: 1,1
AT+KFTPSND=1,"","",“ADU6.TXT”,0,0
CONNECT
hello9
OK
+KFTP_IND: 1,2,12
AT+KFTPCLOSE=1
OK
the main difference is we first connect to the GPRS and then initiate the FTP send.
But i pretty sure on a previous firmware the FTP send alone was enough.
Ideas ?
