hey guys just wondered if you could clear the confusion iv been having
regarding some of your documentation on the fbus protocol.
so far iv been using an old nokia 5130. It works with Andreas
Schmidt's nmon program across a serial cable so i assume its not duff.
Referencing the "nokia" and "nk6110" files in the "docs/protocol"
folder i have worked i should be using the FBUSv2 protocol for the
phone.
I used the example on embedtronics
(http://www.embedtronics.com/nokia/fbus.html) and have managed to
implement working code that extracts the version details (not to
difficult as he gives the exact byte sequence to send). The problem i
have encountered comes when i compared the byte sequence i had to send
to get version info compared to what i thought i would have to send
using the documentation u guys have put together.
the sequence to send to extract the version referenced from
ebedtronics is this
1E 00 0C D1 00 07 00 01 00 03 00 01 60 00 72 D5
this is all good up to byte 7, byte 6 is the frame length and the next
5 bytes are the the {block} or payload from what i understand from
consulting the "nk6100" file is that the block should be 03 00 ... i
see this in the ebedtronics example (byte 10-11) but there is also
00, 01, 00 before... i can not find any description of why these bytes
are there but when i modify the frame to exclude them i get no
response...
really i want to send msg type 0a and block 0x0070 so as to get the
network info but it doesn't work so im hoping you guys could lend me
some help as im tearing my hair out haha
my end aim is to be able to query the phone for info on its current
cell and strength and also surrounding available cells and their
current strengths... if anyone knows a better way of doing this that
isnt going to give me the same head acks please let me know
cheers for everyone work on the project hope you all had a great
Christmas's and are looking forward to an awesome new year!!!
