SIM900 a HTTP

[Richard Kaličiak]

Dobry den,

pouziva niekto GSM modul SIM900 a HTTP protokol?
Mne to akosi vobec nefunguje, tu je vynatok z komunikacie:

AT+CIPSHUT
SHUT OK
AT+CIPSTATUS
OK
STATE: IP INITIAL
AT+CIPMUX=0
OK
at+cstt="web.vodafone.de","",""

ERROR

at+gmm
SIMCOM_SIM900
OK
at+gmr
Revision:1137B04SIM900M64_ST
OK


Naproti tomu TCP/IP spojenie fungovalo, vyskusane s "netcat -l 2001", 
ale HTTP ani za svet, stale ERROR.

V com moze byt chyba?
