I'm making these project that connects two arduino nano wirelessly using hc-05 master/slave communication but at the same time i want to communicate to my pc wirelessly. i dont know how will my pc receive the datas from the arduinos if they are already using the tx/rx pins. i'm thinking that it is possible to use a esp wifi module on the one arduino to communicate with my pc but since tx/rx pins are being used by the hc-05 i am unable to do it.
Some options you might be able to use:
Bluetooth on one Nano is reconfigured on the fly to talk to other Nano or PC. This means Nano controls Bluetooth's power supply.
One nano has an extra Bluetooth on software serial to connect with PC
retire a Nano and put Bluetooth on a Node-MCU instead, thereby communicating with PC via WiFi
Retire one Nano-plus-Bluetooth, and use an ESP 32, which has both Bluetooth and Wifi built-in.
The list goes on......
i'm trying to create a sign language translator gloves using both hands, do you think master slave communication on arduino will work as i expected it to do ? my knowledge about master and slave communication is only limited and i dont know if its the right thing to do
I haven't the faintest idea of the detail but the principle sounds fine. I assume you will use accelerometers in the gloves, and Arduino analyses the movements. I'm sure that has been done before. The actual communication of the data will be the easiest part.
I would guess that the hardware of choice would be Nano or Pro Mini in the glove bluetoothing to a Node-MCU. Note only does NodeMCU have built-in WiFi, but its extra speed and memory might be important.
I might point out that this master/slave stuff is only a procedure in order to establish the connection. It doesn't actually have any bearing on communication.

thank you very much for your response i appreciate it ! although i am a little bit confused on how will i use the Node-MCU and bluetooth, do i connect the bluetooth to my nano then connect it to the node mcu ? then the node mcu will communicate with my pc ?
