Wireless communication among 3 devices


I am doing a project with an insole sending data from sensors to the computer via bluetooth. Now, I want to add another foot and send data to the computer too. I understand that bluetooth protocol just supports communication between 2 devices at the same time.

Would you give me some advice about the best wireless communication technology I could use for this project? Should I send the data from one insole to the other insole and after sending both to the computer?

Thanks in advance!

If you want to stay with the use of Bluetooth communication with the PC from Arduino A you could create a wireless link between Arduino B and Arduino A using a pair of nRF24L01+ transceivers and modify the code on Arduino A so it sends to the PC the data from Arduino B as well as its own data.

Another possibility is to use a third Arduino C connected by USB to the PC and connected by nRF24 to each of Arduino A and Arduino B.
