We are pleased to announce the Mbed OS 5.9.2 release is now available. This is the latest patch release based on the feature set that Mbed OS 5.9 introduces.

Summary

In this release, we have updated mbed-coap to version 4.5.0. This brings fixes for the following issues:

• Hardfault during reconnection retry with Thread
• mbed-coap: extra response received after registration
• Incorrect CoAP request blockwise response handling

There was a LoRaWAN issue LoRaWAN "Tx Timeout" does not trigger Error Event, which has been fixed in this release. If the radio is unable to transmit, it is considered a fatal error and the application is now notified.

In the FSM of the Cellular Connection module there was an issue where the code would crash if the SIM interface was closed too early. This has also been fixed in this release.

To allow the application to choose the default WiFi interface by calling the function, WiFiInterface::get_default_instance() , we have provided default WiFI interfaces for Ublox and Realtek devices.

We have added iAP and Bootloader support for GR-PEACH and GR-LYCHEE, and binary WiFi drivers for MTB_MXCHIP_EMW3166.

There are also a number of other fixes and code improvements.
