    The VX4500 was the first attempt to get CDMA phones working. Bryan did all the testing and it worked for him somehow. Since then, the phone is listed.

    Because we don't have CDMA networks in Germany, I wouldn't get any far with playing around, if the phones doesn't have some test mode, in which a network is simulated (which I really doubt).

    My decision to stop working on CDMA phones is because the protocol implementation for this phones really sucks. I have all the documents from Sierra Wireless and I know that the fully implementation of it more than enough for such software as PhoCo but I haven't seen one phone yet that has implemented more than dialing or retrieving the network quality (except the Moto V710).

    If things are gonna change in the future (with newer phone models) and I have someone with the technical skills needed to do some tests for me, I maybe change my mind.

    Are you really interested???

    Thank you for your response.

    Well I am not an expert but I have done some VS 6.0 C++/VB programming and work with php and perl programmers. I also work for the largest wireless firm here in the states - however in IT, not the cellular part. I may have access to some pretty good resources. I have a qualcomm (cdma - BREW) development kit. With that software and a serial port sniffer I have managed to capture the serial port communication from my vx4500 while it is pulling the ENTIRE file system out of it's memory. This includes phonebook, call logs, in/out sms messages, wallpaper, voice memos, ringtones - everything. The send seems to be all binary but the data coming back seem to be mostly ascii. The only thing missing is notification from the phone when some event occurs such as an incoming call/sms etc. There may be a pin on the connector that goes logic high during an event like that. If you desire to move forward I would be willing to devote some time to helping you with equipment/logs/asking questions around this office etc. You have made such a great software. It would be shame to not make the support wider don't you agree? If it supports CDMA verizon phones better, I'd buy it!

    BTW, I KNOW that LG phones can send battery and signal level info through the serial port. I have seen it on our "Smith Micro mobile office software."

    I will pay what ever it cost as well. That would be really awsome if you can get zorro to get phone control working with cdma phones.

    Lanmanger: Is LG phones the only phones that you have been playing around with to get the battery, singnal, etc..

    Well since I work for Verizon, and since they gave me a LG phone that is all I have tinkered with. I do however have access to most of our upper end CDMA phones as the group that sits next to me carries around an assortment of PDA'S and Blackberrys. I guess if Zorro were willing to work with me I would do some research into them. I believe all our phones use some set of the CDMA at commands.


    I confirmed tonight that Bryan was right:
    AT+CBC? does return the battery level and AT+CSQ? returns signal strength on my vx4500.


    Still trying to detect incoming calls/sms messages.

    I'am willing to work with you but the history has shown that there are very little options. If you find a way to get the phone reporting at least incoming calls/SMS notifications, I'll do whatever is needed to put it into PhoCo.
    But please keep in mind that it has to be the delivered somehow over the AT-Command Interface.

    Don't spend much time on the phonebooks because I know each phone has it's own format, for which it is hard to build a common solution. Beside, phonebooks can be gathered elsewhere (see PBConverter).

    Another interessting thing would be to retrieve call lists.

    Here is what I have found so far.....

    Lg won't divulge the command set; they say it is a trade secret?!?!?!

    The vx4500 is based on the qualcomm MSM6050 chipset.

    Most of our phones are based a qualcomm chipset.

    The at command set would be in firmware. I believe I can extract that from the phone.

    If that yields no clues I may be able to write a small BREW applet that responds to the command set you are already using. Brew is platform compatible with all qualcomm chipsets. So with one small applet, you may be able to cover all Verizon phones.

    The SURF SDK I have retrieves the phonebook, all call logs, all sms messages from my phone.


    This chipset is used in other cdma desktop modems so there is hope.

    I think these chipsets can deliver NEMA GPS location data as well.

    I'll keep you updated.

    Do you know if this would be valid for Sprint PCS CDMA phones too (specifically the SamSung SCH-A700 [aka: MM-A700])?

    If you want to BREW up something, drop me a mail. I'll tell you what commands are needed to work with PhoCo.

    But don't take it too easy.... that's what I'm doing the right now for some other phones... and it's *****ing
