Most importantly, to link your Nucleo device to the IBM Watson IoT Cloud, you will need this information for use in the serial terminal after flashing the FP-CLD-WATSON1 firmware (MQTT_IBM_STM32F401RE_Nucleo-IKS01A1.bin)

In Registered mode the format of the string is:

ssid=<YOUR_SSID>, seckey=<YOUR_WIFI_SECURITY_KEY>, authtype=<WPA2>, qos=0, username=use-token-auth, password=<IBM_WATSON_SECRET_TOKEN>, hostname=<IBM_WATSON_ORG_ID>.messaging.internetofthings.ibmcloud.com, devicetype= <IBM_WATSON_DEVICE_TYPE>, orgid=<IBM_WATSON_ORG_ID>, deviceid=<IBM_WATSON_DEVICE_ID>, ibmmode=registered,
