Meck v1.12: RX log, RX packet counter, plus T-Deck Max power fixes

[pelgraine]

v1.12 is a polish-and-power release across all three companion devices. The headline addition is an on-device Rx Log packet sniffer -- a live view of every packet your radio hears -- available on every build. Alongside it: an unread badge for the SMS inbox, a batch of T-Deck Max power, wake, and GPS fixes, and a set of channel and repeater refinements.

What's New in v1.12

Rx Log packet sniffer -- all devices

A new on-device packet sniffer, mirroring the Rx Log in the MeshCore companion app. Open it from Settings -> Rx Log >>. It captures every packet the radio receives -- including relays destined for other nodes, since capture happens before filtering -- into a buffer of the most recent 100 packets, newest first. Each entry shows the route type (flood/direct) and payload type, the receive time and wire size, the packet hash, the hop path, and the channel hash/name (group messages) or the From/To node hashes (addressed packets). For channel messages your device can decrypt, the decoded "sender: message" line is attached too. The log is RAM-only and clears on reboot.

A running RX packets count also appears on the radio details page on the home screen, just beneath the noise-floor reading. It counts flood and direct packets received since boot and resets on reboot or when you change radio parameters.

SMS Inbox unread badge -- 4G and Max

The SMS app's inbox entry now shows a count of unread received messages in brackets (e.g. SMS Inbox [3]), and the badge disappears once everything is read. Read state is stored per message on the SD card, so the count survives reboots and modem power-cycles. Opening a conversation marks it read.

T-Deck Max power, wake, and GPS fixes

• USB-C wake after shutdown -- after a full power-off, plugging in USB-C now reliably powers the Max back on. The Max uses the SY6970 charger (0x6A); its BATFET shutdown is now handled to match, so charger plug-in re-wakes the board.
• GPS power -- GPS power on the Max is routed through the XL9555 I/O expander rather than a dedicated pin; powering it on and off now works correctly.
• CPU frequency scaling -- idle / boost / low-power CPU management to trim current draw, with the low-power floor held at 80 MHz (40 MHz breaks I2C on the Max).
• Idle BLE power -- the BLE controller now stays powered down until you first turn Bluetooth on, reclaiming its idle current in the standalone-first default. This applies to all ESP32 BLE builds, not just the Max.
• Minesweeper -- grid alignment fixes and a larger 15x20 / 50-mine board sized to the Max e-ink panel.

Channel and repeater refinements -- all devices

• Region on incoming messages -- the message path-detail view now shows the resolved region for scoped channel messages it recognises.
• Path detail -- the route line now reports hop count and bytes-per-hop (e.g. "2 hops (2-byte)"), and the last-message age line shows hop/byte info.
• Repeater admin -- two new configuration commands: Set Flood Max Unscoped (flood.max.unscoped) and Set Flood Adv Max (flood.max.advert).

Documentation

The README and the hyperlinked Meck_README_v1.12.pdf are updated for this release.

First-Time Flashing

Each build comes in two forms:

• <name>-merged.bin -- bootloader, partition table, and firmware in a single image. Flash at address 0x0. Use this for a first-time flash, when coming from other firmware, or if a device will not boot after an update.

• <name>.bin -- application firmware only. Use this to update an existing Meck install, including OTA updates from your phone (Settings -> OTA Tools).

The partition layout supports dual OTA slots, so the previous firmware remains on the inactive partition as an automatic rollback target if a new image fails to boot.

Build Files

Grouped by device. Each variant ships as a merged (-merged.bin, first flash) and non-merged (.bin, OTA / update) pair.

T-Deck Max (every variant runs the 4G modem and ES8311 audio together)

• Max -- BLE / WiFi / Standalone

T-Deck Pro

• Audio -- BLE / WiFi / Standalone (PCM5102A: audiobook player, alarm clock, voice notes)
• 4G -- BLE / WiFi / Standalone (A7682E modem: SMS & phone app)

T5 E-Paper S3 Pro

• T5S3 -- BLE / WiFi / Standalone (NOGPS)

Documentation PDF

Meck_README_v1.12.pdf is included in this release -- it covers all keyboard controls, touch gestures, screen navigation, settings, and feature documentation for every platform, in PDF form for convenience.
