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.

Bug fixes and/or feature enhancements

Firmware version: 18.99.3.p10.5 to 18.99.3.p17.9

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.

Description

Bluetooth

  • 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.
