From: Jérôme Pouiller <jerome.pouil...@silabs.com> It seems that in the old days, the RSSI information could be missing. In this case, in order to not pollute the RSSI stats, the frame was dropped (!).
It is far better to mark the frame with the flag RX_FLAG_NO_SIGNAL_VAL. In add, the problem seems now fixed in the firmware (at least, it has not been encountered with recent firmwares).
