Tapping signal/battery in header now also shows device's own telemetry
(temperature, humidity, pressure, GPS) when available. Triggers a self
telemetry request on sheet open. Data comes from the device contact's
telemetry field.
Room servers forward messages with the original author's 4-byte public
key prefix (roomPostAuthorPrefix). Was ignoring this — all room messages
showed the room server's name as sender.
Now resolves the actual poster's name from roomPostAuthorPrefix by
matching against the contacts list. Falls back to room server name if
the author isn't a known contact.
Also fixes findContactByPrefix to accept 4-byte prefixes (was rejecting
anything shorter than 6 bytes).
Fixes#22
When firmware sends telemetry via both pushTelemetryResponse (0x8B)
and pushBinaryResponse (0x8C), the same LPP data was parsed and
applied twice, causing duplicate sensor entries.
Added hash-based dedup: same payload for same contact within 2s is
skipped. Also added minimum length check for binary responses.
Received message path: Sender → hop1 (near sender) → ... → Us
Outbound path: Us → hop1 (near us) → ... → Contact
Was using outbound path which placed contacts near OUR repeater.
Now uses first hop of the received message path — the repeater
nearest to the sender. Only triggers on received messages, not sends.
When a contact has no GPS, estimate their position from RSSI
observations through multiple repeaters:
- 1 repeater: offset by RSSI distance in deterministic direction
- 2 repeaters: weighted midpoint between circle intersections
- 3+ repeaters: weighted centroid with inverse-square weighting
(closer repeater observations dominate)
Observations stored per-repeater (latest wins), max 8 per contact,
expire after 30 minutes. Each incoming message updates the estimate.
For contacts without GPS, estimate their position by:
1. Finding the first-hop repeater from their routing path
2. Estimating distance from RSSI using log-distance path loss model
3. Placing them at a deterministic offset from the repeater
Uses LoRa outdoor path loss exponent (n=3.0) with reference RSSI
-30dBm at 1m. Distance clamped to 10m-50km range. Bearing derived
from contact public key hash for stable positioning.
- maxRetryAttemptsFloodOnly: 1→0 (was causing an extra retry for
flood contacts that the official app doesn't do)
- isLastAttempt: fix off-by-one (retryAttempt already incremented
when called from _scheduleRetry)
- Reduce ACK timeout jitter from 1-8s to 0.5-2s to avoid long waits
that make the UI appear stuck
- Contact.isFavourite reads bit 0 of firmware flags field
- Toggle favourite via contact action sheet (writes to device)
- Favourites section shown first in contacts tab
- Path size options corrected to [1, 2, 3] bytes
- pushAdvert (0x80): import advert into firmware via cmdGetAdvertPath
before fetching contact, so name/type/location are available
- pushNewAdvert (0x8A): fire-and-forget importReceivedAdvert to store
contact in firmware (data already in push payload)
- controlData (0x8E) discovery: no firmware import (matches official app),
just lookup existing contacts and show generic labels for unknown nodes
- Update meshcore_client git ref to bcbeff0 (burst sync + advert import)
