Here’s a clear, practical guide to connect a USB–TTL converterwith a Bluetooth HC-05 module for configuration and testing. This is the most common setup used before connecting HC-05 to Arduino or ESP boards. 1. Know the HC-05 Pins (important) Typi…
I was thinking about what could be the relation between a DC motor and an LC tank circuit because both of them are fundamentally based on electrical and electromagnetic principles. A DC motor primarily operates with direct current and converts elect…
Yesterday I went to the site on a mountain where I am trying to distribute internet. I had lot of works there so I went early than usual. I had a good reliable wireless point to point link between the tower in the office to the site with two Power …
I have been working on making a wireless network for internet distribution and have been recording some of my works. I wrote about Ubiquiti Lite AP Link: Line of Sight vs. Fresnel Zone and Struggles with Ubiquiti Lite AP and PowerBeam Connections .…
Earlier this week, I shared how I was struggling to connect two Ubiquiti Lite AP 120 antennas . After two more days of attempts, I’m still facing the same issue between my office and home, which are about 350 meters apart. At one point, I dismounted…
I just wanted to write some notes on difference between two PtP and PtMP radio and antenna for WISP network deployment. I have used Ubquiti Lite AP, Lite Beam and Power Beam. Now I have started using the TP-Link wireless outdoor antenna radio such …
Yesterday I attempted to link two Ubiquiti Lite AP units, one at my home and the other at my WISP office, but couldn’t get them to connect. I tested both ends, using wireless and LAN connections. While I could access the Lite AP interface through t…
I had also bought recently TP-link CPE210, EAP110 and EAP225 for testing and then deploying them a sub urban area in the mountains. Both EAP110 and EAP225 are outdoor AP(Access Point) but their is only few hundreds. EAP110 which is 2.4GHz AP for wi…
