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.
