Ashu Joshi.
Felix GalindoI am aware that the conduit runs a mosquitto mqtt broker to communicate with LoRa mDot sensor node. Is it possible to write a node.js app that retrieves the LoRa data, process it, and when then publish something to another mqtt broker like Amazon AWS IOT?
Note, I am not “forwarding” the LoRa sensor data itself, I am processing it and then pushing some data to AWS.
Thanks in advanced for your help.
Jason ReissThis sample nodejs app shows how to connect to the local mqtt.
Felix Galindo@Jason, I understand that part and plan on doing that. What I want to know, is if I am able to connect to amazon AWS IOT mqtt broker and push some data to it?
Jason ReissI do not see why that would not be possible.
Ashu JoshiJason – can I use a remote broker – by changing the LoRa-network- conf file – by specifying the host and port?
Jason ReissIf I said no, would you still try it?
It should work as long as it doesn’t require authentication. There is no config for username and password.
Ashu JoshiJason love,love your answer. I actually tried it – because I saw the option in Advanced LoRa Configuration to set the MQTT Host and Port! You may like the story 🙂
I am beginning to understand this much better. The first baby step I had taken was to run the SUB client on Mac on the same local network as the GW. That works like charm – of course it has to.
Then I made the STUPID mistake of using the IP address of the MT GW as the Host Address yesterday – not because I did not know what I was doing BUT simply because I was using the IP Address of the MT GW constantly to do SSH and it was on my mind.
When I read your response, I corrected it – and VOILA it is indeed working 🙂
