Talaria TWO + STM32 Evaluation Kits
STM32CUBE MCU + Talaria TWO Wireless System Development Platform
Overview
The Talaria TWO software expansion for STM32CUBE is a fully contained application for interfacing STM32L-series and U-series MCUs to the Talaria TWO Wireless Modules. It consists of application software for the STM32Lx and Ux MCU to create ultra-low power Wi-Fi edge-of-network designs for battery-powered, direct-to-cloud connected IoT products.
This package supports the InnoPhase IoT Talaria TWO Wi-Fi + BLE5 Wireless Modules (INP1010/INP1011/INP1012/INP1013). These easy-to-use, integrated modules are mounted on the Talaria TWO EVB-A (INP3010/INP3011/INP3012/INP3013) boards for quick evaluation and development.
The expansion pack software includes a serial interface application running on NUCLEO-L433-RC-P, NUCLEO-L4A6ZG and NUCLEO-U575ZI-Q that enables SPI or UART communication with the Talaria TWO Module EVB-A. The serial applications simplifies the module interface for various functions, including:
- Control: setup/configuration, message send/receive, sleep/wake
- Wi-Fi: scan, connect/disconnect, power management, RSSI, counters
- BLE: HCI command support, GAP/GATT profiles
- Sockets: client/server, UDP/TCP, send/receive message
- mDNS: setup/stop responder, add/remove service
- Cloud: MQTT messaging, Publish/Subscribe, AWS & Azure Examples
The NUCLEO-L4A6ZG, which includes the same functionality as above but scrambles the serial communication between the MCU and Talaria TWO for added security.
Configurations
InnoPhase IoT Host API (HAPI) software commands are integrated into the existing STM32L4 code and accessible through function calls. Once called, the STM32 MCU will send a message over SPI or UART to Talaria TWO.
Talaria TWO receives the messages, interprets the commands and takes action. Wi-Fi connections, BLE usage and network communication are all managed within Talaria TWO.
The process of creating WiFi Cloud Connected devices is simplified to straightforward function calls within the STM32 MCU. For example, connecting to a WiFi network uses the command:
hapi_wcm_connect(hapi_wcm, ssid, passphrase)
Connecting to AWS uses the commands:
init_and_connect_aws_iot()
start_receiving_message_from_aws()
start_sending_messages_to_aws(pub_msg,strlen(pub_msg))
The software is applicable for interfacing and Talaria TWO module with an STM32L4 MCU. Complete example applications are included to further expedite evaluation and development.
Creating cloud-connected products using STM32L4 and Talaria TWO could not be easier!
