Wireless Mesh Lab: BLE and Lightweight Gateways
Prototype BLE pairing flows and bridge lightweight payloads to HTTP.
Overview
Pair devices safely, manage RSSI thresholds, and route packets through a gateway container you deploy locally. Labs emphasize pairing journals and rollback paths when firmware OTA fails mid-transfer.
Included focus areas
- BLE pairing threat modeling checklist
- Gateway container with structured logs
- RSSI sampling scripts with annotated graphs
- OTA rollback drills with staged artifacts
- Snapshot testing for AT command sequences
- Security review templates without exposing keys
- Load testing scripts capped to classroom scale
Outcomes you can evidence
- Ship a gateway repo with rollback-tested OTA path
- Document pairing decisions for an external reviewer
- Capture latency histograms for three environments
FAQ
Are radios included?
Two certified modules ship with the cohort; spares are available at cost, not covered by tuition.
Can enterprise teams join?
Yes—volume billing routes through our corporate desk with separate MSAs.
What is out of scope?
Carrier-certified LTE modules and tower testing are not included.
Participant notes
“Gateway logging templates from week 4 landed directly in our sprint review. RSSI drill felt tight but fair.”
