It Started With a Hardware Limitation I have been using Quectel GNSS modules in my designs for a while. They are reliable, well-documented, and the support ecosystem is solid. But the module I had been using had one problem that I kept running into: no external antenna support . For most projects that is a minor inconvenience. For a marine vessel monitoring and control system , it is a non-starter. A vessel hull blocks sky view, antenna placement is critical, and the difference between a clean fix and no fix at all often comes down to whether you can mount the antenna where it actually has line of sight. An integrated antenna in a sealed enclosure below deck simply does not cut it. So I went directly to Quectel. The Conversation With Quectel I reached out through their official sample request channel. I was not expecting much — most component manufacturers have a standard process: fill out a form, wait, get a few uni...
First of all what is ngrok? ngrok exposes local servers behind NATs and firewalls to the public internet over secure tunnels. This can be used by developers who want to run webhooks with https if you dont have a local ssl certificate. For example telegram, Facebook etc use webhook but they only allow ssl. If you want to know more about the ngrok , <---- please click this link for more information. The script after setup the ngrok in the local machine you can run the ngrok command to start the tunnel. in my case i run the ngrok as a service which i have explained in my previous post . After the service is running you can run the python script or your preferred to fetch the public_url from ngrok which can be use to automate the process. For example Telegram Bot with webhook enable only communicates with https urls so from this method you can get the randomly generated https url to use in such scenarios. In case if you have a doubt about usage of ngrok and automation ...
