Release Notes for Gecko OS Edition 4
To install the latest version of Gecko OS on your device, use the DFU Update Command or Gecko OS Studio (GSS).
Gecko OS 4.1.11 GA Release December 2019
This documents the changes between Gecko OS version 4.0 and Gecko OS version 4.1.
This Gecko OS release adds many new features and fixes.
This Gecko OS release adds a DMS provisioning feature.
New power management features have been added , including system shutdown.
A coredump facility has been added. See system.debug.coredump_enabled.
You can now specify a TLS client chain different to the server chain. See:
WLAN and SoftAP can now work concurrently, on different channels. The setup web command now works with WLAN/SoftAP concurrent mode. network_verify now works with WLAN/SoftAP concurrent on different channels. The Web app now supports password verification on the fly . See SoftAP Features and Variables.
SoftAP Wi-Fi RF transmit power can be managed independently from WLAN TX power. See softap.tx_power .
A Network Bridge Command API feature allows data streaming between an Ethernet connection and the device Soft Access Point. Inbound Ethernet packets become outbound Wi-Fi packets on the soft AP interface, and vice versa.
The softAP MAC filter allows MAC addresses to be whitelisted or blacklisted for connection to the softAP.
A new wlan.backoff variable allows specifying attenuation per Wi-Fi channel and modulation group.
A new wlan.cca_mode variable allows specifying the Clear Channel Assessment mode.
Wi-Fi PTA support is now provided. See wlan.coex.mode.
There is now a Native C API function to query Ethernet link speed: gos_ethernet_get_link_information().
Timing with 31 microsecond resolution is now available.
GPS is now supported on the Hurricane Demo Platform. A Hurricane GPS SDK example has been added.
New and improved SDK app examples include:

|Topic||Description||Solution or Workaround|
|Peripherals||GOS permits configuration of more than one function associated with a peripheral, such as a USART. However the peripheral does not function correctly when this is done.||Take care not to configure multiple functions for a single peripheral.|
|mDNS||The mDNS service works with Bonjour, but not with LLMNR. See mdns.service.||Install Bonjour.|
|Channel 14||Channel 14 is not supported by WGM160P. See wlan.scan.channel_mask||No workaround|
