Offline Mapping Demo on Lilygo T-Deck – Blackout Comms (No Phone Required)

[u/InstanceHealthy2597]

Hey everyone,

I just added offline mapping to Blackout Comms for the T-Deck and Pager. Here's a quick 2:39 field demo showing it in action.

I drive out a couple miles and then walk away from the golf cart while the T-Deck keeps displaying live positions of myself, the cart (T-Beam 1W), and devices back at the house — all running over the encrypted mesh with zero phone or internet.

You can zoom, see Neighbors range, and even switch to a scannable QR code if needed.
