Known Issues and Limitations#

ID Issue or Limitation Description GitHub / Salesforce Reference (if any) Workaround (if any) Affected Chip Revision, Hardware, Host Interfaces
NA WPA3 Connection with Hunting and Pecking algorithm takes about three to four seconds. None None
  • Hardware boards: All
  • Chip revision: All
  • Host interface: UART, SPI
NA If the station performs a scan in concurrent mode (Wi-Fi STA + AP), stations connected to the AP may be disconnected. Enable AP after the STA connection is completed. None None
  • Hardware boards: All
  • Chip revision: All
  • Host interface: UART, SPI
NA With powersave, PTA 3-wire co-existence does not work. However, if a weak pull-up is applied on the GRANT pin, the PTA 3-wire functionality works while the power is saved. For further information, refer to Application Notes. None None
  • Hardware boards: All
  • Chip revision: All
  • Host interface: UART, SPI
NA EAP security in the aws_device_shadow application is unsupported on the EFR platform due to memory constraints. None None
  • Hardware boards: All
  • Chip revision: All
  • Host interface: UART, SPI
NA In STA + AP, if AP started first station scan is supported only in channel in which AP is brought up. If multiple channel scan is requested, AP behaviour is undefined. None None
  • Hardware boards: All
  • Chip revision: All
  • Host interface: UART, SPI
NA Auto channel selection is not supported in AP mode when the EXT_FEAT_IEEE_80211J feature is enabled. None None
  • Hardware boards: All
  • Chip revision: All
  • Host interface: UART, SPI
1250359 This build is not WFA-certifiable due to RSNO and WMM issues; fixes are planned for the next release. None None
  • Hardware boards: All
  • Chip revision: All
  • Host interface: UART, SPI
NA In Wi-Fi client mode, disconnections may occur if the AP does not acknowledge QoS null frames when powersave is enabled. None None
  • Hardware boards: All
  • Chip revision: All
  • Host interface: UART, SPI
