HM-10 AT command for RSSI

Hello all, I'd like to measure signal strenght with my android phone of an emetting bluetooth 4.0 drived with attiny or arduino.

the idea is that the arduino reads the RSSI value of the bluetooth signal and send it periodically to the client (here android phone connected). So when I move closer I excpect having a higher signal and when I move away having a lower signal.

I've seen there where AT command for HC-05 ( which is old bluetooth) to get RSSI:
http://forum.arduino.cc/index.php?topic=192696.msg1672099#msg1672099

are there AT command for HM-10? found something here but i'm not sure:

by the way plugin bluetooth on arduino or attiny is quite simple:

thx

So when I move closer I excpect having a higher signal and when I move away having a lower signal.

If a rough order of measure (close, not real close, and far away) is good enough, that might work. But, I doubt it. Don't expect to get numbers that vary linearly with distance. Far too many other factors affect RSSI.

You're the only one that can get to that link, then.

yes indeed, I've seen that rssi value is very approximative, but even with values as close/far, this is good to me.

I've updated the link, as it is an ftp adress, the forum miss understood it.
