Wi-Fi throughput

Throughput test setup

• Environment: Shield Room - Over the Air

• Access Point: Asus AX88u

• DUT: AW611 uBlox (Module: U-BLOX_Jody_W5 M.2) with EVK-MIMXRT1180 EVKA platform

• DUT Power Source: External power supply

• Client: Apple MacBook Air

• Channel: 6 | 36

• Wi-Fi application: wifi_wpa_supplicant

• Compiler used to build application: armgcc

• Compiler Version: gcc-arm-none-eabi-13.2

• iPerf commands used in test:

TCP TX

iperf -c <remote_ip> -t 60

TCP RX

iperf -s

UDP TX

iperf -c <remote_ip> -t 60 -u -B <local_ip> -b 120

Note: The default rate is 100 Mbps.

UDP RX

iperf -s -u -B <local_ip>

Note: Read more about the throughput test setup and topology in 2.

The throughput numbers are captured with default configurations using wifi_wpa_supplicant sample application.

Firmware version: 18.99.3.p10.5 to 18.99.3.p17.9 {#firmware_version_18_99_3_p10_5_to_18_99_3_p17_9_0}

Component	Description
Wi-Fi	After performing independent reset (out-of-band mode), the STAUT fails to connect to the external AP via wlan-connect command, observed command timeout 0x107 error.
Bluetooth	Audio glitches observed with Google Pixel 7 Pro streaming audio after CIS is established with DUT. During Call Gateway (CG) / Call Terminal (CT) Use Case, the firmware periodically sends NULL PDU, which results in frequent Audio Glitch on both CG and CT sides. Heavy audio glitches observed with CIS SRC Google Pixel 7 Pro Continuous audio glitches observed in 1 CIS and 2 CIS for 48_3 and 48_4 config.

Packet lost would be observed in CIS case which causes audio noise. Sequential Removal of CIS Handles as per current Controller implementation i.e CIS Disconnection sequence should be in sequence => CIS - 4,3,2,1 While 4-CIS streaming, audio glitches observed on all CIS SINK with Samsung Galaxy buds While 4-CIS streaming, disconnection with connection timeout observed on first CIS SINK with Samsung Galaxy buds Only two streams (CIS/BIS) with one channel is supported.
