Hello, I'm new to the forum, I do not handle English very well, I use a translator. I tell you I am making a mesh network of mobile sensors, the mobile sensors are arduino and lora rfm95 and dth11, the gateway I want to implement with raspberry connected by serial to arduino and rfm95. between searching and searching I found an interesting experiment link https://nootropicdesign.com/projectlab/2018/10/20/lora-mesh-networking/.


I want to modify this project, since arduino and raspberry communicate through the mqtt protocol, my idea is to connect them by serial port, once that has been modified, how can I mount the server ?? , here are the programming codes. https://github.com/nootropicdesign/lora-mesh


someone can guide me, I also do not understand how to mount the mesh server, since it has
.DS_Store
app.js
package.json
publico


Thank you very much for your answers, any help is welcome.

mounting the mesh server involves first installing the nodejs software package
https://www.w3schools.com/nodejs/nodejs_raspberrypi.asp
 or

Then I recommend the pm2 module to keep your server running even after the raspberry pi reboots

Then download the software from https://github.com/nootropicdesign/lora-mesh  (either 'git clone' or download the zip file and unzip it in a subdirectory on your Raspberry pi)

Then cd to the mesh-server directory and start with 'pm2 start app.js'


Modifying it to talk to your sensors over serial will be more difficult. Start with https://www.npmjs.com/package/raspi-serial or https://www.npmjs.com/package/serialport
