Add null check for return values of functions that are mostly (but not always) checked for null. E.g., since 98% of calls to protocol_stack_interface_info_get_by_id check for null, it is likely that the function can return null values in some cases, and omitting the check could crash the program. |

ARM Mesh networking stack
This repository contains the ARM mesh networking stack that provides support for the following mesh protocols:
- 6LoWPAN with Neighbor Discovery (ND) and Mesh Link Establishment (MLE)
- Wi-SUN
All networking stacks are using IEEE 802.15.4 based radios.
The full documentation is hosted in Mbed OS documentation.
On mbed OS, mesh networking stacks can be used through Mbed Mesh API and Network Socket API.
To see, how the mesh networking stack works, check the example application mbed-os-example-mesh-minimal.
6LoWPAN with ND and MLE
This networking stack is using standard 6LoWPAN and uses:
- Neighbor Discovery Protocol (RFC4861) to locate other devices in the mesh network.
- Mesh-Link-Establishment (draft-kelsey-intarea-mesh-link-establishment-06) is used for establishing and configuring secure radio links.
Wi-SUN
Wi-SUN (Smart Utility Networks) specification is standardized by Wi-SUN Alliance.
