Bug Fixes#
Resolved an issue where the EAP-TLS client failed to send the complete certificate chain during mutual authentication.
Sending Keep-Alive/GARP at the configured Keep-Alive periodicity (default 30 s), independent of data transfer, to avoid interop issues.
Added a new SAPI error code STORE_CONFIG_NOT_AVAILABLE (0x6C) for RSI_REQ_CFG_GET to distinguish "no store configuration available" from generic memory-allocation failures
Beacon drops should not be seen in power save mode in 5 GHz.

Known Issues and Limitations#
| ID | Issue or Limitation Description | GitHub / Salesforce Reference (if any) | Workaround (if any) | Affected Chip Revision, Hardware, Host Interfaces |
|---|---|---|---|---|
| 1582409 | Station forward compatibility with APs advertising various AKMs in the RSN IE is currently failing. | None | None |
|
| 1638284 | The PTK reinstallation test with a random ANonce in the 4-way handshake is passing functionally, but the certification suite is reporting an incorrect failure status. | None | None |
|
| 1484360 | The new cipher suites ECDHE-RSA-AES256-SHA and ECDHE-RSA-AES128-SHA are not recognized in the latest versions of radisus server. | None | None |
|
| 1592218 | WPA3_Personal and WPA2_Enterprise with wrong PSK is triggering Timeout callback handler. | None | None |
|
| 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, 1532130 | 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 |
|
| 1535439 | Observed repeated beacon misses every 5 seconds when using 1.4A7 board 5G band. | None | None |
|
| NA | During mutual authentication in EAP‑TLS, the client transmits both the leaf and intermediate certificates to the server only when using combined certificate chain loading. Intermediate certificate support is not available in individual certificate loading. | None | None |
