Connect the project to your laptop or phone and then chat between the devices without internet or SMS using just LoRa. Serial terminal based
Hey whats up Guys! Akarsh here from CETech.
Today we are going to make a project which can be connected to your smartphone or any computer and it makes that device LoRa enabled messenger. Now when that will be done you would be able to message any other device using the same LoRa messenger. This all is done without presence of 4G/LTE/3G/GSM/WiFi/SMS.
Lets start with the project now
To make this you will need an ESP8266 board, I suggest to use a NodeMCU style board, I used Firebeetle board from DFRobot as it has on board battery charging and monitoring solution.
For the LoRa purpose I used a RYLR896. I highly suggest this module as it is very easy to use over UART using AT commands.
I would also recommend using a PCB to make the project so that adding battery/OLED display/switch/esp8266 doesnt remain difficult. You can order your PCBs from PCBWAY as they offer 10 PCBs for just 5$. Check out their online Gerber viewer function.
The Firebeetle board ESP8266
1. The LoRa module we have is a UART module which is configured using AT commands.
2. The module houses a STM32 MCU which does all the talking to the SPI LoRa module onboard the RYLR896.
3. The commands in the picture are basic ones you may refer to this document for more: REYAX-Lora-AT-COMMAND-GUIDE
4. I still strongly recommend you to go through my YouTube video where I explain this properly.
Awesome diagrams and neat project! Why did you decide to use an ESP8266 as the controller board? Hope to see more projects from you in the future!
Hello Alexander. I liked these esp8266 boards. for this project any board can be used. I will be posting weekly projects. Check my youtube channel for the same video uploads on every sunday.
This is indubitably interesting. I will review it later this week. What other uses can apply to this invention? Can we implement it in a drone/quadcopter or similar?
Yes LoRa technology is certainly interesting and I will be making more projects with LoRa in the months to come. You can certainly implement this in drones but Lora is not reliable and is sometimes slow so you should not definitely use for controlling the motion of the drone but you can use it for sharing data.
Another great video ,congratulations .On the code you put AT+SEND= 0, Normally is the adress of the device we gonna send the message right ?Soould it be changed according different devices ?
