Episode notes
App-Driven Portable Wi‑Fi Tool
- The WLAN Pi Go is purpose-built as a portable, app-driven Wi‑Fi testing device rather than a throughput tester.
- It focuses on sniffing frames, measuring signal, and decoding packets while tethering to a phone or tablet.
MagSafe-Like Phone Attachment
- The Go snaps magnetically to the back of an iPhone and connects via a USB‑C cable for data and power with no battery to charge.
- It includes a port to attach an external spectrum analyzer like the Lucid for combined Wi‑Fi and spectrum scans.
Update The Go Via App, Not SD Cards
- Use the Go's AB partition layout and the WLAN Pi app to update firmware without reflashing EMMC manually.
- Keep home directory data non-persistent to protect user data across updates while enabling safe updates.
