the most device I have seen are using R1 by default and the only R2 are
my HID devices.

I am no baseband expert, so let me see if I understand you right. In the
case we don't know the page scan repetition mode we should use R2 in
prefer of R1 or even R0? Does this have disadvantages if the devices is
in R1 or R0 mode? I ask because we found that connecting with R1 by
default gives us a significant page time improvement.

If only R2 makes sense in case that we don't the exact value, somebody
should bring up an errata to the HCI working group ;)
