I konw that the WICED studio support freeRTOS and ThreadX. In the project, how to configure for freeRTOS or ThreadX?
You can modify or create a new make target on the right hand side of WICED Studio to include the appropriate RTOS-Network stack for your project. For FreeRTOS, the make target would be snip.scan-BCM943364WCD1-FreeRTOS-LwIP download download_apps run. For ThreadX, it would be snip.scan-BCM943364WCD1-ThreadX-NetX_Duo download download_apps run.
