Is it still an issue to connect the HC05 to Rx0 and Tx0 when I've got the Mega not connected to the computer? When I run my final code I have it powered off of a battery and figured the Rx0/Tx0 would be fine to use since the USB isn't being powered.
That's a really good point about serialEvent as when I have it connected to any input except Rx0/Tx0 is doesn't read a value in, because it isn't being directed to do that. Thank you.
I've read that page up and down but I'll give it another go. Is it as simple as and if statement about Serial1 or Serial2 and then reading in that data?
Ultimately my goal is to have Serial1,2,3 read in data then push it out Serial through my HC05 to a computer. The whole system will be powered by battery and will have no hard connection to the computer except through the HC05 connected to Rx0/Tx0.
Thank you for your speedy response and help Robin2.
