Key Features | API Changes | Bug Fixes | Chip Enablement

Key Features#

  • Verification of the Roaming feature.

API Changes#

None

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.
