I kept seeing those ESP32 toys where you plug it to your PC / Linux and have a touch screen change when Claude Code / Cursor / Codex is asking for some permission, but I didn t want to go that far. I also missed a way to remote control the agent chat when away from the computer. I glanced at my mobile and then it hit me: why not bluetooth? BT got a decent reach, doesn t depend on WiFi (specially with AP isolation), never exposed to the internet (looking at you TailScale). So here s my first attempt. There are some rough edges on Linux, non-working on OSX, but we ll get there.
