Moi, seuraavalla koodilla saan jotain onnistumaan, mutta sitten alkaa tökkiä.
Keksiikö joku heti vian koodista?
EDIT: Taitaa olla parempi kokeilla ftp-siirtoa, vinkkejä siihen?
AT+CREG?
AT+CREG?
AT+CGSOCKCONT=1,“193.229.9.132”,“www.kolumbus.fi”
AT+CSOCKAUTH=1,1,“w454921”,“salasanani”
AT+CHTTPACT="",21
Error waiting the request
AT+CHTTPACT="",21
Error waiting the request
