Bug fixes and/or feature enhancements#

Firmware version: 18.99.6.p34 to 18.99.6.p40#

Component

Description

Zigbee

Zigbee Coordinator and Router are disconnected during BLE connection pairing and bonding with a mobile app for the first time.

Parent topic: Bug fixes and/or feature enhancements

Firmware version: 18.99.6.p40 to 18.99.6.p46#

Component

Description

Wi-Fi

Fails to establish a persistent connection when the device attempts to reinvoke the second stored Persistent Group

Bluetooth

NCP cannot work after flash uart bins for both host and device side

Parent topic: Bug fixes and/or feature enhancements

Firmware version: 18.99.6.p46 to 18.99.6.p47#

Component

Description

Wi-Fi

Enabled mbedtls 3.x

Parent topic: Bug fixes and/or feature enhancements

Firmware version: 18.99.6.p46 to 18.99.6.p47#

Component

Description

Wi-Fi

  • Enabled mbedtls 3.x
  • Host sleep with WoWLAN fails due to command response timeout (cmd 0x10d) during MCU sleep/wake transitions on WiFi NCP over UART, leading to system assert during sleep exit
  • Ping failures observed during concurrent network operations (fast ping from AP backend and DUT), with ICMP unreachable errors indicating routing/forwarding issues and performance degradation under specific network load conditions

Parent topic: Bug fixes and/or feature enhancements

Firmware version: 18.99.6.p50 to 18.99.8.p10#

Component

Description

Wi-Fi

  • Enabled mbedtls 3.x
  • Fail to set band to 2.4G in wifi_test_mode application

Parent topic: Bug fixes and/or feature enhancements

Firmware version: 18.99.8.p10 to 18.99.8.p68#

Component

Description

Wi-Fi

  • Fixed WPA3 SAE security failure observed in WiFi CLI app during initiating connection with AP.
  • Fixed TX power increase of ~3 dBm observed after connecting to a DFS channel and then reconnecting to a non-DFS channel. TX_POWER_LUT_EXTENSION_SUPPORT did not account for the one-channel DPD case, causing TX power to exceed the configured limit on subsequent non-DFS channel connections.

BLuetooth

  • Implementation of PaWR (Periodic Advertisement with response) feature

Coexistance

  • Fixed driver assert issue when wake up wifi cpu1
  • Wi-Fi throughput drops to 0 when Wi-Fi and OT traffic run concurrently on non-overlapping channels at an RSSI of -80 dBm.
  • Fixed high PING latency (up to ~1876 ms average ~397 ms) and packet loss observed with external FEM in Wi-Fi + Thread coexistence mode. RF control lines were switching excessively between Wi-Fi and Narrowband, disrupting Wi-Fi PSM operation and degrading throughput/latency.

Parent topic: Bug fixes and/or feature enhancements

Firmware version: 18.99.8.p68 to 18.99.8.p141#

Component

Description

Wi-Fi

  • Fixed Wi-Fi RF Test Mode continuous-wave tone transmission stopping when run for a long duration (30 seconds to 15 minutes).
  • Fixed an issue where DHCP renewal was not triggered when roaming between independent APs sharing the same SSID.
  • Fixed an issue where EAP-TLS authentication failed with TLSv1.2 in the wpa_supplicant example.
  • Fixed an issue where wlan-scan-opt parameters incorrectly applied to subsequent normal scans.
  • Fixed an issue where the ip_addr_t type field was left uninitialized in net_configure_dns() when IPv6 was enabled.
  • Fixed an issue where Wi-Fi ceased to function after receiving an 802.11k RRM beacon request for a 5 GHz channel when CONFIG_5GHz_SUPPORT=0.
  • Fixed an issue where the DUT failed to fall back to legacy roaming after 802.11k/11v roaming returned no usable target AP.

Bluetooth LE

  • Fixed an issue where BLE TX power set above 10 dBm via vendor command 0xFC87 was reset to the OTP/calibration default (~8.3 dBm) upon BLE connection establishment.
  • Fixed an issue where all Bluetooth commands became unresponsive while Wi-Fi continued to function normally after approximately 3–4 hours of Wi-Fi/BT coexistence testing.
  • Fixed an issue where both Wi-Fi and the DUT hung up after approximately 50 iterations of a concurrent Wi-Fi connect/ping/disconnect and BLE init/advertise/disable loop stress test.
  • Fixed an issue where BLE advertising and scanning failed after repeated bt init / bt disable stress cycles (~600 out of 1000 iterations).
