[Bitpim-devel] Re: Better 8100 camera pic protocol

[bfaye <bf...@ya...>]

I just want to add in more packet descriptions so we got it in the mailing list
archive.  I got a rough grasp of the how the camera file reading request and
response packets look like, unfortunately, I only have my phone to try.  So if
anyone else other there want to splice in some code to test with their 8100,
it'd be cool to see if I'm on the right track.  Here are the additions:

p_sanyo8100.p (don't forget to do makepackets after you add in the changes):
PACKET sanyonumofcamerapicrequest:
    * sanyomediaheader {'command': 0x09, 'subcommand': 0x0072} +header
    2 UINT {'constant': 0xffff} +word
    172 UNKNOWN +pad

PACKET sanyonumofcamerapicresponse:
    172 UNKNOWN +pad
    1 UINT numcampics
    6 UNKNOWN +pad2

PACKET sanyocampicfilenamerequest:
    * sanyomediaheader {'command': 0x09, 'subcommand': 0x0073} +header
    2 UINT {'constant': 0xffff} +word
    161 UNKNOWN +pad
    1 UINT reqindex
    10 UNKNOWN +pad2

PACKET sanyocampicfilenameresponse:
    8 UNKNOWN +headerstuff
    154 STRING +filename
    1 UINT num1
    3 UNKNOWN +pad
    1 UINT num2
    1 UNKNOWN +pad2
    1 UINT num3
    10 UNKNOWN +pad3

PACKET sanyocampicfilerequest:
    * sanyomediaheader {'command': 0x09, 'subcommand': 0x0074} +header
    2 UINT {'constant': 0xffff} +word
    155 UNKNOWN +pad1
    1 UINT fileindexnum
    16 UNKNOWN +pad2

PACKET sanyocampicfileresponse:
    8 UNKNOWN +headerstuff
    150 DATA data
    1 UINT packetlength
    3 UNKNOWN +pad1
    1 UINT indexnum
    15 UNKNOWN +pad2
    1 UINT unknum

The following method can be added into com_sanyo8100.py, and you can test it by
calling it at the beginning of getcalendar (at least thats how I've been
testing it, I'm a Python noob).  It assumes you have at least one picture,
since it tries to grab the contents of the file at index 0 (which doesn't seem
to match the fileNAME at index 0, probably 2 separate indices):

    def getcamerapics(self):
        req=self.protocolclass.sanyoinitcampicread()
        res=self.sendpbcommand(req, self.protocolclass.sanyocamresponse)
        req=self.protocolclass.sanyonumofcamerapicrequest()
        res=self.sendpbcommand(req, 
                  self.protocolclass.sanyonumofcamerapicresponse)
        self.log("got %d camera pics" % (res.numcampics,))
        for c in range(0, res.numcampics):
            req=self.protocolclass.sanyocampicfilenamerequest()
            req.reqindex=c
            res=self.sendpbcommand(req, 
                      self.protocolclass.sanyocampicfilenameresponse)
            self.log("campic filename: " + res.filename)
            self.log("campic num1: %d" % (res.num1,))
            self.log("campic num2: %d" % (res.num2,))
            self.log("campic num3: %d" % (res.num3,))
        d=150
        while d==150:
            req=self.protocolclass.sanyocampicfilerequest()
            req.fileindexnum=0
            res=self.sendpbcommand(req,
                      self.protocolclass.sanyocampicfileresponse)
            self.log("campicfile indexnum: %d" % (res.indexnum,) )
            self.log("campicfile unknum: %d" % (res.unknum,) )
            self.log("campicfile packetlength: %d" % (res.packetlength,) )
            d=res.packetlength
            
        return

You can modify getcalendar so it starts like this (optional):
    def getcalendar(self,result):
        self.getcamerapics()
        result=com_sanyo.Phone.getcalendar(self,result)
        ...
