We currently set the lwIP pbuf pool size small - to 5 x 576-byte buffers. This is insufficient to hold a single DTLS handshake flight, so can cause cloud client connections to fail. STM-based platforms are failing handshake because of this. (K64F works because it doesn't use the pbuf pool for reception, but lwIP does recommend drivers use the pbuf pool). Not changing the default memory sizes here, as intended for a patch release, but adding mbed configuration options to allow the numbers to be adjusted for memory tuning in an application. In a future minor revision, I would recommend increasing the default PBUF_POOL_SIZE - we are well below lwIP's out-of-the-box default - and offsetting by a reduction in MEM_SIZE for the drivers that don't use PBUF_RAM. |

ARM mbed OS
mbed OS is an open-source embedded operating system designed for the "things" in the Internet of Things (IoT). mbed OS includes the features you need to develop a connected product using an ARM Cortex-M microcontroller.
mbed OS provides a platform that includes:
- Security foundations.
- Cloud management services.
- Drivers for sensors, I/O devices and connectivity.
mbed OS is modular, configurable software that you can customize it to your device and to reduce memory requirements by excluding unused software.
