Re: [Bluez-users] Is "HCI_Read_Rssi" is the only option to get RSSI value from "Non-discoverable" Device?

[Ichigo Bleach <sara200t@hotmail.com>]

Thank you Marcel for your reply.

As you pointed out, I went back and read the spec and found that it is absolutly true.

My understanding, Read_RSSI will give the result after compare with the golden recieve power range, instead the Inq_result_with_rssi will just give me the real power recieve in dBm.

I think I would be better off go with the inquiry option. However, my next concern is:

1.) Can the Non-discoverable mode device response to the inquiry_result_with_rssi of the connected device or not-conected but pair device(Known the address)?

Thank you very much for your time.

Best regards,
