Yes, you need to make a previous connection before you can read the status parameter (e.g. RSSI or link quality) of a connection. You may do it at the HCI level (though not recommended by Marcel, e.g. hcitool cc ) or by upper level transport protocol (recommended, e.g. rfcomm). >handle and to "handle" is the connection handle of the connection u have made and "to" is the timeout field.

Yes, you need to make a previous connection before you can read the status parameter (e.g. RSSI or link quality) of a connection. You may do it at the HCI level (though not recommended by Marcel, e.g. hcitool cc <BD_ADDR>) or by upper level transport protocol (recommended, e.g. rfcomm).

>handle and to
"handle" is the connection handle of the connection u have made and "to" is the timeout field. You may need to look into the source-code of "hcitool" which comes with bluez-utils - then everything will be clear.

Hi everyone!

I want to program an example using the hci_read_rssi function but I don't
know how to do it because I don't understand its parameters, specially the
uint16_t handle and the int to. I don't know how ti initialize them.

Moreover, I don't know if its necessary or not to make a previous connection
with another function.

Can anybody help me?

Thanks a lot.
