“Connect the project to your laptop or phone and then chat between the devices without internet or SMS using just LoRa.
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.
Step 1: Parts
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.”
