Sony Xperia Z5 Compact RSSI is null if setReportDelay() is used

[Alex K.]

Hi together,

I'm trying to scan for BLE Beacons and I got the problem that if I set setReportDelay() to a value unlike zero, the onBatchScanResults() method is called and all RSSI values are null.

If if set setReportDelay() to zero, the onScanResult() method is called and getRssi() works as expected.

I read in another post that some SmartPhones have a bug with batching scanresults. I logged the isOffloadedScanBatchingSupported() and it is true.

So, is the z5 known for that bug or am I doing something wrong?

Best regards, Alexander

Hi,

This seems to be a common bug with the setReportDelay() functionality. On Samsung 6 and 6 Edge packets reported with this mode will show exactly the same RSSI value. It used to be any number, but now it's often a value between -100 and -128.

So if you want a reliable RSSI measurement, don’t set setReportDelay() to anything else than zero.
