mbed-os-5.2.2

We are pleased to announce the mbed OS 5.2.2 release is now available.

This release includes support for new targets: Sara-N, MAX32625, FRDM-K82F and k22512.

Other key highlights are:

• Implementation of the API for serial port flow control in NRF51 targets.

• Support for 6LoWPAN PAN ID filter added to mbed mesh API configuration.

• Updated u-blox ODIN-W2 drivers.

• A number of bug fixes and tool improvements.

Known issues in this release

There is currently a DNS resolution failure in Thread mode. This causes a failure in the mbed-os-example-client and will be fixed in a subsequent release. This can be worked around by reverting to mbed-os-5.2.0.
