inertia. the state of being surrounded by so many questions arising out of self-doubt that it renders you action-less. do I even have what it takes? am I actually creating value for somebody? why do I keep thinking of such big things when I can’t accomplish the smallest ones? why? why? why?

To understand all about nodes, gateways, and servers, first, we must understand what a LoRaWAN or LoRa network is. LoRaWAN (long-range wide area network)LoRaWAN is a low-power, wide-area network (LPWAN) protocol designed to enable long-range communication between LoRa-based devices and the internet. LoRaWAN builds on the underlying LoRa technology, adding network and application layer features that make it a complete and standardized solution for deploying IoT devices and services.

Communication between two LoRa end-node devices can happen seamlessly. Both end-node devices include the LoRa E5 Mini Board, which switches quickly between sending and receiving messages — making two-way communication possible. In this setup, communication begins with one device sending a message and waiting for confirmation. Upon receipt, the receiving device sends a reply confirming the message was received.

LoRa (Long Range) is a type of wireless communication technology designed to send information over long distances with low power consumption. It uses a special technique called chirp spread spectrum (CSS) modulation, which operates by continuously changing the frequency of a transmitted signal over time. This varying frequency generates a waveform (resembling the sound of a bird chirping), allowing it to send signals over long distances without using a lot of power.

I know things are not working well for you, you are doubting yourself again, aren’t you? But, can a sword take its shape before being burnt? this is your journey. you are in the making. don’t just stop yet. no. no. choose to burn, choose to let go of everything that’s been holding you back, choose to burn away the doubt that has creeped up in your mind, choose to let go of the inner voice that keeps telling that you are not enough. you are not that voice, you are the owner of that voice.

A single cell is not sufficient for some devices. To achieve the desired voltage, the cells are connected in series to add the voltage of cells. To achieve the desired capacity, the cells are connected in parallel to get high capacity by adding ampere-hour (Ah). This combination of cells is called a battery. Sometimes battery packs are used in both configurations together to get the desired voltage and high capacity.

When launching EC2 instances, it's important to understand different storage options:🔹 Block Storage vs Object Storage:👉 Object Storage (S3): Best for large volumes of unstructured data (e.g., images, backups). 👉 Block Storage (EBS, EC2 Instance Store): Best for transactional data and frequently accessed small files. 🔹 File Storage:👉 EFS (Elastic File System): AWS-managed network file system, scalable across instances.

👉 EC2 Instances = Devices in your home (like your phone/laptop) 👉 NACLs = Firewalls that control who/what gets in or out 👉 Route Table = Traffic director – decides where packets go 👉 Internet Gateway (IGW) = Modem that connects your home to the internet 1️⃣ These EC2 Instances resemble devices in our home N/W NACLs resemble firewalls; they are also called virtual firewalls 2️⃣ We have to allow for any traffic to communicate through our NACLs 3️⃣ If traffic is allowed in NACL, it is passed to...
