Device to Device communication without internet

Question

Hi,

I am trying to figure out the best way to establish a communication channel between two telpo t10 devices without requiring internet.

Do you have a recommended approach for this? Do you know if both WIFI direct and Bluetooth Low Energy would work?

Also, does Telpo support 5 GHz WIFI range  (if I were to use WIFI direct)

Answer 1

T10 can connect 2.4G+5Ghz WIFI.I think you can try RS232

I wanted to avoid using extra cables. Is there any reason why you would recommend RS232 over WIFI/bluetooth?
