Send data inbound to devices with TCP, UDP, and SMS using Hologram Cloud Messaging

Hologram makes it easy to send messages to your devices. You can send messages to your devices using TCP, UDP, or SMS.

To send TCP, UDP, and SMS messages to your device through the Dashboard, go to the device's page via the general Devices page and select Messaging.

TCP and UDP

Our Cloud Data feature allows you to send a TCP or UDP message to a specified port on your device. This is helpful when you want to send messages to your device using only data.

SMS

SMS is commonly used by IoT devices to send command, configure, and control messages such as setting the APN because it does not require setup.
