alright might sound odd hoping can clear bit. have arduino uno wired 16 channel relay board , hc-06 bluetooth module attached uno. got pins being used including analog pins. have samsung galaxy s4 permanently attached car, , paired bluetooth. want able use samsung galaxy s5 in pocket pair , control relays. if out of car can still show people.
from read can't have 2 devices paired @ same time? wondering if bought second hc-06 , attached in parallel other 1 if both connected? hope isn't confusing. looking see if plausible or not?
sounds should work me...give try ha. don't see issue honest, hc-06 devices should ignore trying input on tx pins. diodes may of use in application?
