 Hello, and welcome to this video about the STM32L0 low-RAW discovery kit. The low-RAW WAN protocol is an open global standard used for secure, carrier-grade IOT LP WAN connectivity over a wireless low-RAW network. The low-RAW WAN certification program guarantees the interoperability and the technical flexibility to address multiple IOT applications. The main assets of low-RAW WAN are very low power consumption, very long range capability, the low node cost and the overall cost of the network deployment, an open and standard low-RAW WAN protocol driven by the open low-RAW Alliance, a native AES 128-bit encryption protocol and a true and GPS-free indoor-outdoor geo-location. The B-L072Z-LR WAN-1 low-RAW discovery kit is a development tool to learn and develop solutions based on low-RAW and FSK-OOK technologies. This discovery kit features an all-in-one open module CMWX1ZZ-ABZ-091 from Mirata. The module is powered by an STM32L072CZ and an SX1276 transceiver. Arduino UNO V3 connectors allow you to customize your own node thanks to our huge XNUCLEO portfolio. You will need the B-L072Z-LR WAN-1 discovery kit. It includes an ST-Link V2-1 embedded debug tool interface, LEDs, push buttons, antenna and USB OTG connector. You will also need a computer with the free keel integrated development environment, the iCube-LR WAN low-RAW WAN software expansion package, your favorite terminal, we will use TerraTerm, and of course, an internet browser. For the gateway, we will use a multi-connect conduit gateway from Multitech with an embedded M-TAC-Laura 868 accessory card dedicated to the 868 MHz frequency. A SIM card will be inserted in our gateway to provide internet access through the 3G network. Let's connect to the Multitech gateway. As you can see, our gateway is connected to the GSM network and so to the cloud. The low-RAW link is also operational. So our gateway is ready to relay data between the low-RAW network and internet. We will customize low-RAW WAN software expansions for STM32-Cube to send STM32 low-RAW WAN discovery kit as connected IoT cloud from our low-RAW discovery kit. Then we will compile modified source code. Finally, we will flash the compiled binary to the low-RAW discovery kit. During startup, our discovery kit will display data required for activation by personalization or ABP. These elements provide device identification and data encryption. The discovery kit state is known thanks to logs sent to its virtual serial port. Now let's connect to the low-RIOT cloud network server to check if the gateway is well connected and the data correctly transmitted. We can register our device to the low-RIOT cloud. The low-RIOT cloud is now receiving data from our discovery kit. We can read the STM32 low-RAW WAN discovery kit as connected IoT cloud sent by our device to the low-RIOT cloud. STM32 microelectronics proposes three low-RAW solutions powered by STM32. Low-RAW discovery kit, low-RAW expansion board for STM32-nucleo, and low-RAW-nucleopack. Thank you for watching this video.
