Improved LoRa Camera - Part 1
The original ESP32CAM board is a small and low cost camera board and in a previous project I developed code to allow the transfer of the images to a remote receiver with LoRa. That Arduino code will be found in the SX12XX-LoRa library here; https://github.com/StuartsProjects/SX12XX-LoRa. The ESP32 processor used on the ESP32CAM is, when the camera and SD card are connected, critically short of…

How not to read a GPS with TinyGPSplus
I often see posts on forums where users are having problems reading the location parameters from a GPS using the TinyGPSplus library. Latitude and longitude or altitude can report as 0 for instance. Or you can have a situation where the location remains static for some time and only changes sporadically.

Introduction
Testing Antennas Really Is Easy
I have previously written an article about testing the real world effectiveness of antennas on LoRa devices but recently it occurred to me that the availability of the small ESP32 LoRa and OLED display boards such as those made by Heltec and Lilygo made it much easier to have small battery powered portable LoRa devices which have OLEDs for showing signal reception data such as RSSI and SNR. These…
Improved TTN LoRaWAN Node for XIAO LoRa
Despite being very easy to build, this board is a fairly powerful LoRaWAN node, ideally suited for long term battery use which is also very small and light; only 6g + sensor + battery. Can now be fitted with a FRAM non-volatile memory for saving OTAA session state. Can be used for point to point LoRa too. There was a TTN\LoRaWAN node program published for the previous board, but that program did…
