Data da publicação: 17 dezembro, 2020

The Azure Sphere 20.12 OS quality release is now available in the Retail feed. This update includes enhancements and bug fixes in the Azure Sphere OS; it does not include an updated SDK.

The 20.12 release incorporates the following changes and bug fixes:

  • Reduced the maximum transmission unit (MTU) from 1500 bytes to 1420 bytes.
  • Improved device update in congested networks.
  • Fixed an issue wherein the Wi-Fi module stops scanning but does not respond with a completion event if a background scan is running and the active Wi-Fi network is deleted.
  • Fixed a bug wherein I2CMaster_Write() returns EBUSY when re-sideloading the app interrupts operation.
  • Fixed an Ethernet connection issue for devices with both Wi-Fi and Ethernet enabled. In some cases, upon rebooting the device the Ethernet link-up appeared to be down when it is connected to a network.
  • CVE-2020-17002 - a patch for this CVE addresses an issue where the Azure IoT C SDK did not enable host name validation when using wolfSSL to establish a TLS connection with Azure IoT.
