AT+CFUN=7 not supported by Huawei E173

Hi Marcel, I got a problem with the change "huawei: Use correct command for setting offline mode". The command AT+CFUN=7 is not supported by all Huawei modems and so the E173 is not working anymore. PCUI: > AT+CFUN=7\r PCUI: < \r\n+CME ERROR: 50\r\n This modem supports only these functionality level: 0, 1, 4, 5 and 6. I don't have the specification of this modem and so I don't know what level we need to set here. Do you have an idea on how we can resolve this problem? Thanks. -- Nico
