Sample project for X-NUCLEO-S2915A1 using Contiki/6Lowpan available for simple UDP sender, receiver, sniffer and edge router. Is there any other sample project from STM I can refer?

I am working on a project to create a star network between a router to a number of sensors over 6lowpan using Contiki. Router will pass the messages to border router. Router and border router is connected to main power, while sensor is battery powered.
