Hi Alex,
Denis - I am being directed to the ITU 36.133 spec here

Sure, same document/section where 27.007 refers to for <rsrp>. But
unfortunately 27.007 only defines the range 0..97 where 0 is <rsrp> <
140 dbm. How 3GPP decides to represent <rsrp> values between 156 and
140 is up to 3GPP. If your vendor is using negative integers in AT
commands, then that is a vendor extension and not something that is
permitted by ITU v.250.
This document defines this in 9.1.4
I can't see where RSRP_-17 is defined anywhere but the strong
implication to me is that this number should be -17
Can you confirm where it states that these numbers cannot be negative
numbers as I cannot find that requirement.
V.250 Section 5.3.1. Notice that 27.007 never uses negative integers,
there's a reason for that.

OK - they say it's fine and you say it's not. I don't have the time to
be the middle-man here.
Although I'd like to, clearly I won't be able to contribute this Quectel
support upstream.
Thanks anyway,
Alex
