# ObexFTP F.A.Q.

## F: Using ObexFTP left me with all folders and their contents gone.

### A: Don't worry.

Sometimes the phone gets confused. Just power-cycle it and everything should be there again.

## F: Is it possible for the provider to read my flexmem?

### A: Yes.

Roman KRASZEWSKI programmed his phones micro controller to do so. Your provider might do so likewise. Generally the controller can access the phone like your desktop software can. There are memory limits though.

## F: Is there more info on the BFB protocol than your docs?

### A: None that I know of.

I'm always keen on completing my picture on BFB. Please send me all your "strange" logs.

## F: Is there a way to read out the information on my current location?

### A: Yes. It's done with unsolicited messages.

You first need to prepare your communications to expect unsolicited messages and then enable unsolicited messages (AT+CNMI). You can then subscribe to some cell broadcast channels (AT+CSCB). When you recieve such a broadcast via an unsolicited message you can easily decode the payload.

The GPRS_AT_CommandSet.pdf lists the messages to be expected in section 2.4.3 on page 96. The commands involved are described in section 2.3.9. "GSM 07.05 for SMS" page 60pp.

## F: I would like to archive both my pictures and SMS.

### A: To do daily SMS backups I recommend gsmlib.

            gsmsmsstore --source /dev/mobilephone --baudrate 57600
             --store SM --backup --destination $HOME/S45/my.sms

and for your phonebook

            gsmpb --source /dev/mobilephone --baudrate 57600
             --phonebook SM --destination $HOME/S45/sm.pb

To backup your pictures and alike you need ObexFTP.

## F: How can I listen to the voice memo (.vmo) files?

### A: There is a converter available. It's called "vmox"

The voice memo files are plain gsm coded audio with just some strange padding added.
