Hi,
I added some log.
The right information got from device:
00 00 03 12 5B 00 01 3A 46 55 4A 49 54 53 55 20
4D 42 41 33 30 37 33 4E 50 20 20 20 20 20 20 20
34 37 30 32 42 42 53 32 50 41 41 30 31 31 46 34
00 00 00 00 00 00 00 00 0F 00 00 40 0B 54 01 3C
The wrong information got from device:
00 00 00 00 03 00 12 00 5B 00 00 00 01 00 3A 00
46 00 55 00 4A 00 49 00 54 00 53 00 55 00 20 00
4D 00 42 00 41 00 33 00 30 00 37 00 33 00 4E 00
50 00 20 00 20 00 20 00 20 00 20 00 20 00 20 00
Compared to the right log, it seems one extra byte *00* is added after
every byte.
Do you have any idea what can cause the problem?
Thanks for your help.
