Say I have two HC05 modules set to communicate with each other. They are 50 feet away from each other, and since the range of the sender is 30 feet and the range of the receiver is 30 feet, will they be able to connect? Or is it the range of the sender that matters?
Considering upgrading to a BlueSMiRF Gold for a car remote project, and I want to know if I am 360 feet away since the BlueSMiRF has a range of ~328 feet if the BlueSMiRF will be able to communicate with the receiver at 350 feet and if it is beneficial to upgrade the receiver as well.
HCO5 range depends on the smallest range. Edit: corrected.

Note that any given range in a specification is normally under ideal conditions. In practice you will get nothing like that.
You can not add up the ranges like that.
I'm sure @weedpharma meant to type HC05 rather than HC03
For measuring 2-way communication distances both devices must be able to work over the full distance.
If there is only 1-way commnication in theory only the transmitter needs the range. However a more sensitive receiver (and or better antenna) can make up for a poor transmitter so it is a complex issue.
If you plan to work at the edge of a devices's capability I reckon you will just have to suck-it-and-see.
