This is my first message to this forum, for this reason, excuse me if I'm using the channel incorrect.
Well, I'm doing a university project using the bluetooth shield V1.2 and arduino mega, between others points I need to measure the bluetooth signal to then use it on arduino logic.
Could someone help me in this case?
Thanks

measure the bluetooth signal
The Bluetooth radio must provide that data. It is part of the BT spec, and on iMac it is easily viewed:
Similar to Wi-Fi connections, Bluetooth uses a radio as a means of communication, so if you are experiencing drop-outs then the first thing to do is check the signal strength, which is computed for Bluetooth devices as a Received Signal Strength Indication (RSSI) value. While the connection stability may vary a touch with different RSSI values, the following is a general guide to what constitutes a good or bad connection:
0 to -60 --> good
-61 to -70 --> OK
-71 to -90 --> poor
less than -90 --> bad
So, look at the BT spec, look at your module datasheet, and determine how to interrogate the module for the RSSI. Then translate that to Arduino code.
