Thanks, it looks like a bug in the E1750. The E1750 hangs when Diafaan SMS Server requests the list of received messages. You can try setting the 'Modemreboot' command in the advanced settings to AT+CFUN=1,1 (this is the default value in Diafaan SMS Server 1.7.1.0) but this is not the ideal solution.

There is a newer version of the firmware available for the Huawei E1750 on the Huawei download page (search for E1750). The Huawei firmware usually only works for devices that are not branded to a specific network.
Be careful with applying new firmware, it may disable the device!

I sent you an email with communication log.
I forgot to write, but when I plug modem into USB port, modem is working for a while in a good way, but after some time, the following error shows up.
I tried enabling the 'ResetAfterTimeout' and 'ResetAfterNetworkFailur' but it still doesn't work.

Hi Michal,

I just tried the Huawei E1750 but I can't replicate the problem. One thing you might try is using the other COM port (the Huawei E1750 uses two COM ports). Another option is to enable the 'ResetAfterTimeout' and 'ResetAfterNetworkFailure' options in the Advanced properties of the GSM Modem Gateway.

If you send the communication log (see http://www.diafaan.com/how-to/log-modem-problems/) to dms@diafaan.com I can have a look to see if there is a possible explanation for this behavior.

Regards, Henk

Hi,
I have a problem with Huawei E1750 reconnecting after error on AT+CMGL=4 command.
Is it normal? How can I fix this?
Best regards,
Michal
