I'm using an HC-05 and I have it successfully wired up to my ATMega328P so that the HC-05 Tx is tied to the ATMega328 Rx and HC-05 Rx is tied to the ATMega328P Tx.
So I'm assuming that the data received on the wireless signal is then written to the HC-05 Tx pin. That sends it to the Rx pin of the ATMega328P (since it is wired as I explained above).
Is that a valid description?
Just trying to untangle this in my mind so I understand that received data (via wireless) appears on the Transmit (Tx) pin. I could almost see that wirelessly received data could be found on Rx pin since it is really data that is received but I think the two are separate.
Guess About HC-05 Chip and Wireless Data
I'm guessing that a chip on the HC-05 writes the received data to the serial port (Tx), right? And then data that i want to be sent over the bluetooth from the HC-05 would be read on the Rx pin which is then converted to wireless and sent by the HC-05?
Can someone clear it up for me?
