Topic: help help red mesh with lora rfm95 and raspberrypi b+ (Read 842 times) previous topic - next topic


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

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


mounting the mesh server involves first installing the nodejs software package

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
