Goal The goal is to start using a Digilent Pmod ESP32 module with AT commands. Hardware Requirements: Software Requirements: Challenge The default Firmware on the PmodESP32 module uses USRT0 for logging, and listens to UART1 for AT commands. But UART1 is not exposed to Pmod pins, so you cannot work with it until you change…
Goal Develop a project on a PC and store it in a Git repository (e.g. GitHub).Deploy it on a Raspberry Pi by cloning the repository, installing dependencies, and running the application.Keep a clean and repeatable workflow for updating the project from PC to Pi. Intended workflow PC (development) → GitHub repository (source of truth) →…
Contents Part 1 — Introduction When designing a wireless sensor network, one of the first challenges we encounter is communication. In many cases, the requirements are quite different from traditional wireless systems. We are not trying to stream video or transfer large amounts of data. Instead, we typically need to transmit only a few bytes…
Event-driven Wi-Fi ↔ hotspot switching on Raspberry Pi using NetworkManager. Automatically falls back to hotspot when no network is available while allowing manual hotspot override.
