A full Arm IoT stack from sensors to the cloud
summary
Complete Arm stack from sensors to cloud: Raspberry Pi endpoints run Arm Mbed and Python libraries, send temperature, humidity, barometric pressure, TVOC, eCO2 and GPS via MQTT to 96Boards Hikey 970 edge nodes that translate into InfluxDB queries and feed an Ampere eMAG cloud server on Packet. Most of the pipeline works and dashboards show multi‑region data (edge nodes in Arizona and India, cloud in Newark) but lightning detection never came online and TVOC/eCO2 need a special init string. Major surprises: 90‑day developer certs expired in the field, embed Linux OS lacked I2C by default, development toolchain required building on Arm laptops.
