Cayenne library problem

Hello Community,

I program a nucleo board STM32F401RE with a WIZnet ethernet module using the mbed and
this library : https://os.mbed.com/teams/myDevicesIoT/code/Cayenne-WIZnet_Library/ but this library has mbed 2 which is deprecated and has not RTOS feautures. Is there any similar library with a new version of mbed with RTOS?

Thanks in advance.

Can you find a generic MQTT library working with your device and add implent the topics https://developers.mydevices.com/cayenne/docs/cayenne-mqtt-api/#cayenne-mqtt-api-mqtt-messaging-topics
