Affected app version

2.7.12-open.2

Affected Android version

Android 16

Affected phone model

Pixel 10 pro xl

Affected node model

Rak4631

Affected node firmware version

2.7.18 and 2.7.19

Steps to reproduce the bug

I was told this is happening because a node with an older firmware is repeating these packets.

If this is happening to you, you would need to find a node that has rssi and snr on the node itself and filter by show only direct nodes. The problematic node won't show up in the list any more.

You could also look at the debug log in the app to find packets that are missing the "hop_start" and "hop_limit" fields

Actual behavior

I get packets where hops are missing. The issue is the sender used to show up with -1 hops or ? Hops on the node list but now they look like direct nodes. These nodes will sometimes contain hops but when the packets missing hops show up the node shows up as direct.

Expected behavior

These nodes I would think should not show up as direct or should ignore the packets that are missing hops.

Screenshots/Screen recordings

See Swami

The top packet is missing "hop_start" and "hop_limit"

No longer in the list

I also just checked on an older version I built from source and the issue is the same it also shows the hop count as ?.
This is 2.7.11
