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 |
|
| 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 |
|
| 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 |
|
| NA | EAP security in the aws_device_shadow application is unsupported on the EFR platform due to memory constraints. | None | None |
|
| 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 |
|
| NA | Auto channel selection is not supported in AP mode when the EXT_FEAT_IEEE_80211J feature is enabled. | None | None |
|
| 1250359 | This build is not WFA-certifiable due to RSNO and WMM issues; fixes are planned for the next release. | None | None |
|
| NA | In Wi-Fi client mode, disconnections may occur if the AP does not acknowledge QoS null frames when powersave is enabled. | None | None |
|
| 1532130 | This build is not WFA-certifiable due to RSNO and WMM issues; fixes are planned for the next release. | None | None |
|
| 1535439 | Observed repeated beacon misses every 5 seconds when using 1.4A7 board 5G band. | None | None |
