Vincent Coubard c17be7efe4 Fix possible overflow of NRF51 os tick. 
The RTC1 counter can increase while the new value for the CC register
used by the os tick is computed. As a result, when interrupts are enabled
again RTC1 counter and CC register value are equal. If these two values are
equal then the interrupt for the CC channel used by the OS tick will be
generated the next time the RTC counter reach that value.
In other words, the next OS tick will occur 131 seconds latter.

This issue possibly concern all NRF51 targets with 32K of RAM but is
only visible on NRF51_DK target when their is heavy BLE load.

ARM mbed OS

mbed OS is an open-source embedded operating system designed specifically for the "things" in the Internet of Things (IoT). It includes all the features you need to develop a connected product based on an ARM Cortex-M microcontroller.

mbed OS accelerates the process of creating a connected product by providing a platform operating system that includes robust security foundations, standards based communication capabilities, built-in cloud management services, and drivers for sensors, I/O devices and connectivity. mbed OS is built as a modular, configurable software stack so that you can readily customize it to the device you're developing for, and reduce memory requirements by excluding unnecessary software components.

Current release

Our current release series is mbed OS 5.1:
