WM2000 Programmable Wireless IIoT Module

The WM2000 is the first programmable wireless Industrial IoT (IIoT) module offered by Tibbo. This cloud-native device incorporates Wi-Fi (802.11a/b/g/n over 2.4GHz/5GHz) and Bluetooth Low Energy (BLE) interfaces that introduce several new features, such as Wi-Fi auto-connects, wireless debugging, over-the-air (OTA) updates, and TLS support. As a vendor-agnostic product, it can communicate with Microsoft Azure, Google Cloud, Amazon AWS, and virtually any other cloud services provider.

The WM2000's hardware incorporates two high-speed serial ports. It also features software I²C/SPI ports, onboard flash and EEPROM, a real-time clock, and ten GPIO lines — two of which work as external interrupts. Nine lines can be configured to provide pulse-width modulation (PWM) output.

The WM2000 is fully supported by Tibbo IDE (TIDE) and has a dedicated platform that covers all of the module's hardware facilities. The module runs Tibbo OS (TiOS), our highly reliable operating system that achieves exceptional stability thanks to radical OS structure simplification, static memory allocation, full ownership, and meticulous curation of the code base, as well as complete sandboxing of the user's application.

The WM2000 is ideal for creating IIoT solutions that are free from the limitations of traditional wired networks. The simplicity of Tibbo BASIC/C — aided by Cody, our template project generator, and TIDE — ensures timely and cost-effective development of stable, dependable applications.

To test and evaluate the module's capabilities, purchase our WM2000EV Kit.

Dual Tibbo BASIC/C apps

The WM2000 is the first Tibbo device that can store up to two compiled Tibbo BASIC/C binaries (only one can run at any given time). All our earlier products store a single app that can take up all of the flash space not occupied by system files and TiOS. The WM2000 — which has at least four times the flash storage of any predecessor — allows you to store the second app in the space left over from the first one.

A Device Configuration Block (DCB) of the WM2000 allows you to define which of the two apps runs when the device is powered up or reboots (there is an override through the MD button/line that forces execution of the first application). A web app called BLE Terminal is provided for interacting with the DCB through the WM2000's BLE console. Tibbo BASIC/C applications can access the DCB through a provided API.

Simplified Wi-Fi connectivity

The WM2000 features a significantly revamped Wi-Fi API facilitating automatic association with a designated wireless network. This makes the module's Wi-Fi interface as easy to use as the Ethernet port on "wired-first" Tibbo devices. Set the target Wi-Fi network's SSID and password, enable "autoconnect," and the WM2000 will automatically associate with the network and keep associated when in range! This also enables wireless debugging of your Tibbo BASIC/C apps.

All parameters related to automatic Wi-Fi association are stored in the DCB and can be configured via the BLE console or through Tibbo BASIC/C code. A companion app that ships with the module also allows for configuration of the Wi-Fi interface.

Fast Deployment With the L.U.I.S. App

Anyone who has ever deployed a device on a target network knows that complications often come from silly little things, like the configuration of Wi-Fi parameters.

Enters the Loadable User Interface System (L.U.I.S.), our wireless configuration solution for Tibbo devices.

L.U.I.S. allows you to configure compatible Tibbo devices via their BLE interface. The L.U.I.S. app (iOS, Android, web) automatically discovers nearby devices that support BLE configuration. After you select a device to work with, the app loads configuration pages from the device itself. Wi-Fi parameter configuration, IP selection, and many other settings are suddenly within easy and convenient reach!

It gets even better: The WM2000 also supports over-the-air firmware upgrades via BLE using our Tibbo Updater app (iOS, Android, web)!

  1. Although two independent Tibbo BASIC/C compiled binaries (apps) can be stored in the WM2000's flash memory, only one can run at a time.
  2. Several of the WM2000's configuration parameters are stored in the DCB, which is accessible via a new integrated console. Our BLE Terminal web app leverages the Web Bluetooth API (compatible with the Chrome, Chromium, Edge, and Opera web browsers) to connect to the WM2000's console. Configuration properties can also be read and set through Tibbo BASIC/C code.
  3. TLS is supported on a single outgoing TCP connection.
