rbattery = ble.sockreadhnd(sock,0x47) or ''
I want to ask specifically how this function is implemented when extracting the data I want. For example (sock, 0x47) in why 0x47 must be this, what basis.
I want to figure out a function x = ble. sockreadhnd (sock, 22) or'' about extracting data from Bluetooth.
