Re: [android-developers] Re: Problem getting Bluetooth RSSI (Signal Strength)
This only gives the RSSI value found during the device discovery process.

[android-developers] Re: Problem getting Bluetooth RSSI (Signal Strength)
does this give the most recent rssi value or the value from when the
device was connected? does it update the rssi value whenever we call
it?

[android-developers] Re: Problem getting Bluetooth RSSI (Signal Strength)
will the rssi value be the newest updated value? because from what
i've read, the value is from when the device was connected, not the
current state of the device. if that is not the case, awesome.

[android-developers] Re: Problem getting Bluetooth RSSI (Signal Strength)
It may not work because EXTRA_RSSI value is a short type instead of
int. This works great for me:
short rssi = intent.getShortExtra(BluetoothDevice.EXTRA_RSSI,
Short.MIN_VALUE);
Take into consideration that rssi values are usually negative (it
could be dBm but I am not sure).
