Mbed OS 5.8.2 released

We are pleased to announce the Mbed OS 5.8.2 release is now available. This is the latest patch release based on the feature set that Mbed-OS-5.8 introduces.


This release adds new target support for RAK811 and Toshiba TMPM46B.

We have included a new patch version (4.4.1) of mbed-coap. This brings fixes for the following:

  • Block wise messaging call-backs not working logically
  • Allow TCP+TLS transport method to send larger messages without blockwising.

We have also added an update to the drivers for STM32L1:

  • CubeL1: Updated from V1.6.0 to V1.8.1
  • HAL driver: Updated from V1.2.0 to 1.3.1
  • CMSIS device: Updated from V2.2.0 to V2.2.3

We have enabled tickless mode on Silicon Labs targets and added support for the v3.0 pin map on the NUMAKER_PFM_M487 platform.

There are a couple of significant issues which have been fixed in this release:

  • Deep sleep was not unlocking properly in the Timeout class.
  • UARTSerial output not working properly on the REALTEK_RTL8195AM platform,causing the device to crash 6358.

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