Hello Support,
This post is a continuation of the previous post WL1835MOD: Wi-Fi beacon loss while scanning with Bluetooth
As instructed, firmware version (Rev 8.9.0.0.72) was loaded into our custom board and Wi-Fi logs were captured using the gLogger tool following the steps found in here.
Attached are two .csv files of the logs captured. In the first log a download test using Wi-Fi was tested while Bluetooth was not used; meaning that SS1BTPM was not actively running and nothing from Bluetopia was used. The second log used the same Wi-Fi connection; however, this time Bluetooth was being used where SS1BTPM was actively running and a Bluetooth connection with a HSP/HFP device was maintained.
The test command used was:
wget --output-document=/dev/null http://speedtest.wdc01.softlayer.com/downloads/test500.zip
In the first test, it is observed that the time to download the test file was 2 minutes and 31 seconds.
4743.wifi_no_bt_connections_v72.csv
In the second test, the time to download the same file was 17 minutes and 22 seconds.
Version (Rev 8.9.0.0.85) was also tested and yielded the same results.
As mentioned previously, throughput of Wi-Fi drops as well as constant beacon loss is experienced while a Bluetooth connection is maintained. Is there a version for WL18xx that corrects the issues we are experiencing?
Furthermore; it has been observed that there does in fact exist a known issue with co-existence between Wi-Fi and Bluetooth based on the following release notes:
