Arm-based hardware enables IoT devices to talk to each other and transmit critical information either to the cloud or between devices.

Choose the appropriate connectivity protocol and access resources for your application.

Wi-Fi

Wi-Fi is one of the primary protocols used for internet communication. At 5GHz radio bands, Wi-Fi provides the highest speed of any standard. Because of the amount of power that it uses, Wi-Fi is typically used in gateways.

Trigger-based warning system

Develop a trigger-based warning application in this guide. The application sends sensor values to the cloud through an MQTT broker, then triggers actions based on sensor values. This guide uses the Texas Instruments MSP430F5529 LaunchPad, a CC3100 WiFi BoosterPack, and the open-source Energia IDE.

Get started

Learn the basics of BLE development with the Silicon Labs EFR32xG21 2.4GHz SoC starter kit.

LoRa

LongRange (LoRa) connectivity protocol allows IoT devices to communicate short messages over long distances with low power consumption. LoRa is the physical layer protocol as defined by the Open Systems Interconnection (OSI) seven-layer network model. This means that LoRa implements communication at the bits level. The related LoRaWAN protocol sits on top of LoRa. LoRaWAN sits at the data packet level of the stack, and allows low-power devices to communicate with internet connected devices over long ranges.

Set up a LoRa node

Learn how to allow your Arm-based ST boards to send messages from sensors to a LoRa network.

View guide

Get started

Create a private LoRa network that can connect to your IoT devices from several miles away.

View guide

LTE-M

LTE-M enables your IoT device to send data like sensor readings or geolocation to the cloud using low power consumption. LTE-M is a cellular communication protocol that allows your IoT device to send information without any additional infrastructure. To use LTE-M, you need to have cellular LTE coverage in your region.

Recording real-time sensor data

Connect an ultrasonic sensor to the cloud using LTE connectivity on a Raspberry Pi Zero for real-time data.

Zigbee

Zigbee is designed to carry small amounts of data at speeds of up to 250kbps, and over a short distance in a mesh network topology. Zigbee is ideal for many IoT applications.

Integrating Zigbee

Substitute cables or communication methods on existing projects with an Arm-based Teensy board, to add Zigbee capability to your system.
