[BitPim-devel] question about sending data to phone

[Tomáš Bezouška]

Hi, I am using Siemens SXG75 and I like your program. I want to try to make a program to comunicate in same way as BitPim does, but I need your help. I dont know the structure of commands for copying files into phone. FE:

str: Y . . . . 5 . . . . . . . ( b r e w / m o d / j a v a _ a m s / c o n f i g / g a m e s / s p o t . j a r . . .
hex: 59 05 00 01 01 35 E2 02 00 FF 00 01 00 28 62 72 65 77 2F 6D 6F 64 2F 6A 61 76 61 5F 61 6D 73 2F 63 6F 6E 66 69 67 2F 67 61 6D 65 73 2F 73 70 6F 74 2E 6A 61 72 00 00 01 50 4B 03 04 14 00 08 00 08 00 B8 5D 7C 33 00 00 00 00 00 00 00 00 00


I dont know what does 35 E2 02 mean. It is the same for one file. I know it is not the file size. But what is it? Could you help? Thx in advance

Look at p_brew.p and com_brew.py in the bitpim source tree.

Thx for it. I can already see the structure of the commands. Still, I d=
ont undestand last 2 B - F.E.: D6 F2 7E. I know 7E ends every command b=
ut what are those 2B before it? I found in p_brew.p note, that they do=
n't include the trailing CRC and 7f. I guess thats what I am looking fo=
r. But how is it counted? Had a look into com_brew.py, but as I dont pr=
ogram in Python (I use Delphi) it is very dificult to see any sense her=
e.

They are the CRC. The method used is the same as X.25 and PPP.
You can find specs via a Google search.

The .p file specify the various commands. The phone module
then adds the CRC.

Read the BitPim developer doc, especially the bit about the
analyser.

I read what I could on https://svn.sourceforge.net/svnroot/bitpim/trunk=
/bitpim in dev-doc directory but didnt find anything

Pls, help with CRC calculation. I tried several methods, but with no success. I had a look into p_brew.p but there is written "We do not include CRC" So where am I supposed to find it? Just show me an example or something. ThanQ

[Stephen Wood]

BitPim's crc calculations are done in common.py.
