I want to use aws greengrass on esp32 but after lots of debugging I came to know that i have to use free RTOS to use AWS greengrass on ESP32. still i dont have anything concrete. can anybody help me in this matter?
If I understand correctly you want to connect an ESP32 to AWS IoT Greengrass. There is a library in the AWS org in Github for doing that which uses FreeRTOS, but that uses standard protocols, so if you have implementations of those protocols for the ESP32 then you don’t need FreeRTOS.
