Nordic thingy:52 unable to get RSSI values

Hi, everybody,

I managed, through the Nordic library for Android thingylib (github) , to connect to thingy52 and receive in the callback listener ThingyListener the information about the device (e.g. onGravityVectorChangedEvent, onAccelerometerValueChangedEvent, onGyroscopeValueChangedEvent, and so on…).

What I can’t do (and I can’t find how to do) is how I can get the information about the connection with the device, exactly the RSSI values.

Using the BluetoothLeScannerCompat, inside the onBatchScanResults scan callback, I detect the thingy52 bluetooth device, and their RSSI value, but if I set a high scan frequency, for example .setReportDelay(10), it almost always does not detect devices.

 ScanSettings scanSettings = new ScanSettings.Builder()
                .setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY)
                .setReportDelay(10) // frequency of scan
                .setUseHardwareBatchingIfSupported(false)
                .build();

My need is to get at a frequency of 10Hz, or 100Hz the RSSI value of the nordic thingy52, which I can’t get from the ThingyListener events.

How can I do it? Thank you in advance.

For accurate RSSI values you can’t use setReportDelay. Set it to 0 or remove from the code. First of all, batching works quite ok for delays > 5 seconds. Secondly, the RSSI you get there is an average/last/first/no one knows what. Without report delays you’ll get a onScanResult callback instead. One for each advertisement received.

Please, open an issue in the thingy project for this. Let’s keep things tidy. I’m closing this issue.
