SRU Justification ================= [Impact] Less beacons were found in BLE scanning with RS9113 chipset.
[Fix] BLE Scanning is happening for less scan window, which is causing this issue. Scan window value is adjusted (increase)dynamically in firmware when there is no activity on WiFi/BT. Along with this fix i firmware, we have added deep sleep feature in driver. Driver will put chip in sleep state when there is not activity. [Test Case] Conducted tests to confirm BLE scanning results are improved with the driver and firmware changes. Also, ran suspend resume s3, s4 and s5 stress tests to ensure it passed with newly added sleep changes -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1753439 Title: Redpine: BLE scanning for nearby beacons per second is too low and result high loss rate. Status in linux package in Ubuntu: Incomplete Bug description: Steps to replicate the issue: 1. Power on the BT device, then change the terminal by "Ctil+F1" or open another putty to ssh SUT. 2.Use command below to discover BLE device. $ sudo stdbuf -i0-o0 -e0 /snap/bluez/current/usr/bin/hcitool lescan --duplicates --passive | perl -nle 'print scalar(localtime), " ",$_' 3. log as attachment.
