| <note important>If you're a fully remote student, you do not have access to the public part of the network (addresses 157.158.56.0/24); thus, you need to use only IoT devices and services available in the internal IoT WiFi network that IoT devices you're programming can access. Still you may access MQTT messaging via the 2nd MQTT Broker bridged, but it requires specific topics organisation as not all topics are forwarded. Refer to the documentation below.</note> | <note important>If you're a fully remote student, you do not have access to the public part of the network (addresses 157.158.56.0/24); thus, you need to use only IoT devices and services available in the internal IoT WiFi network that IoT devices you're programming can access.
