STMicroelectronics B-L475E-IOT01A Discovery Kit for IoT Node | Engineering Bench Talk



hello I'm Jay Paul carpenter technology specialist here at Mouser electronics I'm here today to introduce the STMicroelectronics BL 475 e IOT zero one a discovery kit for IOT node or the esti IOT discovery node for short STMicroelectronics is a global leader in innovative semiconductor solutions for smart driving and the Internet of Things or IOT the esti discovery IOT node is designed to be a smart node which means that it sits on the edge of the network right before the internet gateway it includes a multitude of sensors and communication platforms to enable a wide range of interfacing options the esti discovery IOT node includes a wide variety of sensors including to digital microphones a three axis magnetometer a 3d accelerometer a 3d gyroscope an absolute digital pressure barometer time of flight gesture sensor capacitive digital relative humidity and temperature sensor it includes four different communication interfaces including btle Wi-Fi dynamic NFC a sub gigahertz transceiver in two frequencies either 868 or 9:15 megahertz depending on your region the esti discovery IOT node is powered by an STM 32 l 475 VG t processor which consists of an armed 32-bit cortex m4 CPU running it up to 80 megahertz the software boasts more than 18 communication interfaces and uses both Arduino and P mod connectors for adding to this already capable board to connect your st discovery IOT note to your host computer for configuration you will need to provide a micro USB a/b cable a host computer running Windows with available USB port and internet connected Wi-Fi router with known SSID and password you will need to download and install the following software for setup st-link v2 driver which can be downloaded from the link provided account creation or Givaudan may be required teraterm our other serial software and a text editor the board now comes with the Amazon AWS demo that publishes temperature humidity orientation and other sensor data to the cloud service and allows a web interface follow the instructions provided on Mauser comm at this link to setup the AWS cloud service the directions describing what I am doing can be found here all links will be provided in the video description as well after completing the Amazon AWS setup you will need to have the following information ready device name as configured in the Amazon AWS setup root certificate ending in dot PE M things certificate ending in dot p.m. CRT private key ending in PE m ke Y and the rest API endpoint address to configure the device open tera term and start configuration select serial in the new connection window select the correct comport from the drop down box to the right and click OK click setup then serial port and set the baud rate to one one five two zero zero and confirm that all other settings match my configuration on screen then click OK click setup then terminal and set the new line receive to auto and new line transmit to LF enable local echo and click OK press the black reset button on the development board and you should start seeing the development information scrolling across the terminal screen configure the device for internet access the instructions will prompt you to press the blue user button to enter configuration mode enter the Wi-Fi SSID and press enter select the Wi-Fi encryption mode input the password and press Enter give the device the AWS credentials to set the root certificate open the file ending NPM with a text editor copy the entire contents of the certificate file I suggest using ctrl a and ctrl C right click to paste the certificate into teraterm do not press control V and click OK then press ENTER to set the things certificate open the file ending NPM CRT in a text editor copy the entire contents of the certificate file using ctrl a and control see right click to paste the certificate into teraterm do not use control-v and click OK and press enter to set the private key open your file ending in PE mkay in a text editor copy the entire contents of the certificate file using ctrl a and ctrl C right click to paste the contents of the certificate into teraterm do not use control-v and click OK and then press ENTER to set the server and thing names copy the rest API endpoint address right click to paste the address into teraterm do not use control-v set the device name as defined in the AWS setup the board will start sending data once it is connected to AWS every 10 seconds for 10 minutes to view the connectivity select the AWS console on your browser select registry select things and then select your thing click on activity you will see a graph showing the connection rates to interact with your thing select the MQTT client under publish window input the following command that you see on the screen or found in the setup document in the black JSON window below copy the statements on the screen or in the setup document click the publish to topic button and watch your boards LED turn on to turn off go to the publish window and repeat the previous instructions changing the word on to off your iot solution is now live are you ready to start development with the smart IOT node then consider the st discovery IOT node the easy way to get an IOT solution started for more information on the st discovery IOT node go to the link shown you
