Hello everyone! I would like to ask if it is possible for two HC-05 bluetooth modules to receive and transmit data. Is it possible that the Master can receive as well as transmit data at the same time, the Slave can transmit as well as receive at the same time?
In my project I need to control to Arduinos (Mega & Nano) in a way that the Mega can send data to the Nano and the Nano can send data to the Mega.
Thanks!

If you would take the time to read the Bluetooth specs, you would have the answer to your question. Bluetooth is time sliced. The master transmits on one slice while the receiver receives on that same time slice. Then the reverse takes place on the the second time slice. Then back to the first time slice.
So, no, Bluetooth CANNOT transmit and receive at the same time. They can alternate very rapidly, especially on the newer versions.
