Example LoRaWAN application for Mbed-OS
But the bulk of the code and the radio pins will be the same on the STM32 side, you just need to modify the 'Board Support Package'.
You're going to have to add in code to initialize SPI or I2C buses to which you've attached sensors, and add code to talk with those sensors. And login to murata and download new reference sheet. And in old reference on antena part is capacitor with value of 0ohm probably should be resistor.
And in new is resistor maybe best thing is to just put wire. Thank you for your advices Goran Mahovlic, actually i already past this step, i have a card with sensors connected in I2C, i need to modify the ST's provided code.
LoRa radios are exceedingly effective at point-to-point communication. You can also own both ends of the communication link, rather than deal with the complexity of a multi-channel gateway radio.
When that is working I just check what I need to copy paste into LoRa code All rights reserved STMicroelectronics. Cookie Notice Cookies and similar technologies enable us to provide you with an optimized user experience and functionality of our website.

Thank you. If your hardware differs marginally from the DISCO implementation you'll need to fork that code into a branch which addresses your board's differences.
I had few design mistakes so here there are Yes, it's my job.As this is a popular subject among those following my posts, I decided to talk about LoRa today. I always wanted to post about the STM32, as it composes a whole family of bit microcontrollers produced by STMicroelectronics. I have several friends who are using this chip outside of Brazil.
They can attest to the successes of this European manufacturing device. This video will show you an STM32 development kit not meant for programming in Arduino, but instead with C language or those that are native to STMicroelectronics. If I'm not mistaken, there are eight companies that produce compilers for STM32, which shows us that there is a sizable global culture concerning this chip.
It consists of architectures ranging from very small chips to STM32 F7, which I consider to be "super powerful". However, it is much more powerful. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. This assembly transmits the data to our "beloved" ESP32, which has an embedded i2c display that displays the packages.
You can see that it only takes 81 milliseconds for preparation, sending, and receiving of the package by the ESP32, as well as for the on-screen display. If the distance is increased, and there is a change in the software, this time tends to increase. Our aim with this assembly is to show the STM32, which is a different chip, sending data in the standard Lora radio. It is important to remember that there are two different hardware pieces that are talking via LoRa radio protocol.
Basically, we have here the Semtech LoRa chip, with some discrete components on the board, including an antenna output. The interface is SPI. At this moment, we must bring up the question of chip speed, which is at above Kbps.
To go far, you must lower the bit rate. It is important to remember that speed is not a concern of LoRa, but rather its scope. The frequency of this device is MHz, and the transmission power is at about 18 dBm, with 3v3 power. I consider this special concerning the STM The kit is more powerful, but the Maple Mini works in the Arduino IDE, which makes it a lot easier for those who are not as knowledgeable with regards to the programming.
Here you can see how simple our scheme is. Then, follow the steps in this picture. This part of i2C has already been removed from the code that I downloaded below. To find out how this code works, simply watch the video. By Fernando Koyanagi Visit my Site! More by the author:. About: Do you like technology? Follow my channel on Youtube and my Blog.

Also is the data in AppData the ones to be transmitted? I want the count and the timestamp to be sent every time the LoRa device transmits.

Do you want to know whether your code is going to work? Or knowing what data will be sent physically? I want to know what data will be sent physically. Is it the data in AppData?
Because the data I want to send is count and seconds. And I stored them in AppData. But, I'm not sure if that is the data that will be sent.
