Generate last byte for MBUS IMEI

[Test_]

Hi!

I'm trying to write program for IMEI on DCT3. I am able decrypt MSid and encrypt IMEI, but in the MBUS frame i don't understand where to find this last byte:

1F 00 10 40 00 1A 00 01 B6 57
[98 BD C2 7F 09 A3 82 AB D9 E8 B5 C5] - Enc IMEI
[35 07 70 10 89 24 92 FF] - Clear IMEI
[B1] - How to claclulate this?
FF
06 - Seq
35 - Chksum

any help?

Hi,

There's alot of samples on using mbus communication, including source codes.

Eg, http://nokiafree.org/forums/t11773/s.html

There's many more around, just make some time to look through the dct3 archives.
