Our multiprotocol solutions for you
Developers adding wireless connectivity to their products face unique and complex challenges. Sometimes, one type of wireless protocol alone does not meet their needs. We offer a range of products capable of hosting different types of wireless multiprotocol solutions.
Concurrent multiprotocol (single-chip)
We provide a software layer called the Dynamic Multi-protocol Manager (DMM), which enables a single radio to run multiple wireless protocols concurrently on an MCU by switching between protocol stacks in real time. This allows the developer to determine a custom protocol priority for every possible state of their system, managing protocol stacks and minimizing latency. While many concurrent multiprotocol solutions rely on fixed-priority implementations, our solution is highly customizable and enables the developer to set priorities according to any state of their system.
DMM currently supports the following combinations (with more to come):
|Zigbee end node (supported devices: CC2652R, CC2652P, CC2652RB)||Zigbee router (supported devices: CC2652R, CC2652P, CC2652RB)||Zigbee coordinator (supported devices: CC2652R, CC2652P, CC2652RB)||802.15.4 Sub-1 GHz collector (supported device: CC1352R, CC1352P)||802.15.4 2.4-GHz collector node (supported devices: CC2652R, CC2652P, CC2652RB)||802.15.4 2.4-GHz sensor node (supported devices: CC2652R, CC2652P, CC2652RB)|
|Bluetooth Low Energy 4.2 peripheral|
|Bluetooth Low Energy 5.1 peripheral|
Example use case: building security system
Security panel running Bluetooth Low Energy and 15.4 Stack Sub-1 GHz concurrently receives an alarm message from a door sensor when the door has been opened. The Sub-1 GHz alarm message pre-empts a Bluetooth Low Energy task in order to deliver the alarm message. Later, the Bluetooth Low Energy task resumes and the user’s smartphone is updated with the alarm status.
Swapped multiprotocol/ provisioning
Swapped multi-protocol is the process of a device exchanging information ((network name (SSID), password, and security type) with an existing wireless network in order to join it, and is often done using Bluetooth Low Energy. This is also known as provisioning.
Bluetooth Low Energy provisioning utilizes Bluetooth Low Energy for the information exchange, but enables a device to join a network for a different wireless standard (Wi-Fi, Zigbee, Thread, etc.). This gives users the ability to provision new devices directly from their smart phone, providing them a user-friendly and consistent experience. SimpleLink MCUs enable both two-chip and single chip, multiprotocol provisioning configurations.
Example use case: thermostat
Bluetooth Low Energy provisioning enables easy setup of devices for the end user. A customer could buy a Wi-Fi thermostat off the shelf, bring it home, connect it to their smartphone using Bluetooth Low Energy, and easily incorporate the thermostat to their home Wi-Fi network using provisioning.
Coexistence (two-chip multiprotocol)
Designers looking to implement Bluetooth and Wi-Fi connectivity in their application can utilize the CC3x35 wireless devices combined with a Bluetooth Low Energy MCU. Using time division multiplexing, two devices are able to share a single antenna without wireless interference, enabling Bluetooth Low Energy (or any 2.4GHz protocol) and Wi-Fi provisioning capabilities, updates to the cloud, and more.
Example use case: electronic door lock
A electronic door lock system implementing coexistence enables the end user to lock or unlock the system using Bluetooth low energy or Wi-Fi on their mobile device. The electronic door lock can also periodically send status updates to the cloud.
