Still can't gry Huawei E1550 to work

Hi all,

I am running Android on the Mini210 and I have plugged in a Huawei E1550
modem and even after configuring it for MODEM only with AT command it gets
detected by Android but won't dial out.

Here is the debug output

[ 1540.467431] usb 2-1: new full speed USB device using s5p-ohci and
address 2

It has a valid working SIM and I have updated apns-conf.xml to include the
correct APN settings etc.

It just does not dial out when I choose the dialup 3G application.

Anyone for this working and if so, what did you do?

Cheers,

Dave, the MODEMs I'm using set themselves up as 4 or 5 USB ports. Check
/dev and see if you get ttyUSB0 ttyUSB1 etc. when you plug in the MODEM. I
have had to do fiddle around to find which one (usually 4 if there are no
other devices) will dial out with an AT command.

The other problem has been getting attached to a tower successfully, and
one embarrassing lost day because I didn't have quotes around the phone
number in the AT command.

Thanks Charles,

I will have a go at it today and see if I can get it working.

It seems a bit strange that it appears as 3 USB ports as I would have
expected it to only appear as 1.

I have a simple terminal app I can run to send AT commands and see which on
responds to them.

Cheers
Dave...

I think one of the ports registers as a storage device and has driver info,
and some others are like partitions and one might not use AT commands but a
proprietary protocol. I'll have to research and write up the details. I'm
just getting into it with Python code to send SMS with data from monitoring
equipment.

I disabled the storage device with an AT command on the PC so that it now
only appears as a modem.

I would like it work work with the standard Android phone interface if
possible otherwise I will have to do similar to what you are doing and
write my own Android app to do AT commands.

Sorry, I must be missing something in your post but what are you referring
me too?
