I wrote a small application for sending SMS (through Bluetooth) from my X51v. I'd be really interested in some feedback regarding (in)compatibility issues.

Right now, I can say it works fine on my X51v (WM5.0, MS Bluetooth stack, VGA mode, PXA270) with my Motorola RAZRv3.

Basically, the application enables you to write the SMS on your PDA and send it to either a manually entered phone number or to one of your contacts' mobile number. Please note that you must pair your phone and PDA before my application can use it.

More info on that webpage I put together:
http://software.zone17.com/zsms.htm

The UI was done with C# and requires NETCF 2.0, whereas the helper DLL was written in C (in order to use the Bluetooth sockets). Interaction with the phone is done through AT commands.

Any comments are welcome.

I don't have the time to test it now, but if this app works as advertised, I will be very happy.

Could you point me to a good location for downloading CF 2.0 for the Ax? Last time I did it, I wound up downloading a bunch of extra stuff from MS that I didn't need.

I believe the download is around 24 Mb, although only ~2 Mb ends up on the PDA. Just go to that link and click on the ".NET Compact Framework Version 2.0 End-User Redistributable" sublink.

I get a communication timeout error using the same Axim (X51v with ROM A06) and a Motorola MPx 220. I do have CF installed because it was installed together with WiFiFofum 2.0. And the phone is paired appropriately...

same here with SonyEricsson K750i and axim x51v A06

The same error here... Axim x51v and SPV c500

The "Connection timeout" error message means that the AT command sequence did not complete within 10 seconds. Did you guys notice if your phone indicated an incoming BT connection? (my phone has a flashing blue light and the display turns on when the serial link is active). I'll test it with other mobile phones at the office to see.

Another test would be to open a serial port connection from a desktop PC to the phone using a terminal program (HyperTerminal would work) and try the following AT command sequence:

AT
[response: OK]
AT+CMGF=1
[response: OK]
AT+CMGS="xxxxxxxxxx" (replace xxxxxxxxx by the destination phone number)
[response: >]
type in message, followed by CTRL-Z
[response: OK]

I'll put in some debugging feature tonight in order to isolate the issue.

It works fine with a co-worker's Sony Ericsson T610 phone. I'll try as many devices as possible today. Be sure to bind to the phone's "Dial-Up Networking" service - it's how I configured both my RAZR and the T610.

I thought I'd lost SMS functionality when I "upgraded" to x51v. Didn't know why the v551 worked with the X5 + Socket card and not my X51v (stupid jerks).

In any case, how do I pay you for your work?

You don't. I did this primarily for myself and I'm just happy that others can actually benefit from it - that's why I'm asking for feedback so I can improve its features and increase the number of supported devices.

On that last topic, I believe adding support for AT+CGMF=0 (PDU mode) will fix the "connection timeout" issues some are experiencing. For instance, it doesn't work on a co-worker's Sony Ericsson S700i.

thanks. I'll try this out with my V600 later this week and let you know.

Hi BB,
When do you intend to have a new version with this added support for us to test?

Hopefully tonight. I'll post an update on this thread as soon as it's ready. I believe most (if not all) phones support the "PDU" mode but I'll probably add a checkbox to the options panel in order to force it into "Text" mode (which is currently used).

Update: I have almost finished the PDU code. It should be done tomorrow night.
