python3-improv: report Foundries enrolment/OTA state in Device-Status (ota block) - #45
Merged
Conversation
… (ota block)
Add an `ota` block to the Improv Device-Status superset (vendor char
e5f10002) so the app/cloud can see, during onboarding, whether the board is
enrolled to a Foundries factory and running the OTA client:
- registered: /var/sota/sota.toml present (the config lmp-device-register
writes and aktualizr-lite.service's ConditionPathExists gate); absent =>
not enrolled to any factory
- factory/tag/hwid/target/os_version: from /etc/os-release
- daemon: aktualizr-lite.service active
- up_to_date: null on the board on purpose — authoritative "on latest target"
comes from the cloud->Foundries API, not a possibly-OFFLINE device
All signals are root-free/best-effort and self-reported (untrusted until
attested, roadmap P2-1). Verified on eink-0167 (currently un-enrolled):
{"registered":false,"factory":"eink","tag":"main-imx93-jaguar-eink",
"hwid":"imx93-jaguar-eink","target":25,"os_version":"5.0.11-25-96",
"daemon":false,"up_to_date":null}.
Supports the app/admin onboard/offboard-to-Foundries feature (BLE-triggered
on-device registration + cloud offboard via Foundries API).

Hot-patching the ota block onto eink-0167 showed the characteristic value truncatedating mid-JSON at 512 bytes (full payload with the legacy flat mirror was ~580). Drop the flat top-level state/ssid/ipv4/rssi/iface mirror (the app has preferred nested net since #41) and add a progressive shrink (time.iso → ota.os_version/hwid) before publish so a long SSID can't silently corrupt the JSON. Re-verified over BLE: complete ota block with registered:false/factory:eink/target:25/daemon:false. Co-authored-by: Cursor <cursoragent@cursor.com>

Summary
Adds an
otablock to the Improv Device-Status superset (vendor chare5f10002) so the app and cloud can see, during BLE onboarding, whether animx93-jaguar-einkboard is enrolled to a Foundries factory and running the OTA client.This is the board-lane half of the Foundries onboard/offboard feature (Alex-directed 2026-07-20): report Foundries state over Improv, with app/admin controls to onboard (BLE-triggered on-device
lmp-device-register) and offboard (cloud→Foundries API, admin-only).
