ok, I found the encoding of the first byte, which represents the first 2
numbers of the oid string.
this program gives:
0x55 => 2.5
0x60 => 2.16
0x2A => 1.2
0x2B => 1.3
0x09 => 0.9
#include <stdio.h>
int main(void)
{
int i;
int v[] = { 0x55, 0x60, 0x2a, 0x2b, 0x09 };
int first;
int second;
for (i=0; i < 5; i++) {
first = (v[i] >> 3) / 5;
second = v[i] - ((first * 5) << 3);
printf("0x%02X => %u.%u\n",
v[i], first, second);
}
return 0;
}
