Contact list display bug fix for all devices: MyMesh.h — added onAdvertRecv override declaration (line 214), alongside the other contact-related overrides.
MyMesh.cpp — added the implementation (lines 374-387). It calls BaseChatMesh::onAdvertRecv() first to let all normal processing happen (auto-add, replay guard, path caching, etc.), then unconditionally looks up the contact by pubkey and bumps lastmod to local RTC time. This way, even when the base class's replay guard early-returns (because timestamp <= last_advert_timestamp), the contact still bubbles up in the recency-sorted contacts list since we're actively hearing it.
SPIFFS.begin(true) auto-formats on mount failure, but the auto-format
itself can fail if the partition contains residual data from a previous
firmware (e.g. stock LilyGo, Meshtastic, or MeshCore with a different
partition layout). When that happens the firmware previously printed
"SPIFFS format FAILED!" and continued in a broken state with no
persistence.
Now on auto-format failure:
1. Find the SPIFFS partition via esp_partition_find_first()
2. Erase it completely with esp_partition_erase_range()
3. Call SPIFFS.format() + SPIFFS.begin(false) with up to 3 retries
Added #include <esp_partition.h> under ESP32 guard.
The existing first-boot display feedback ("Formatting storage...
First boot - please wait") is unchanged -- it fires on the initial
mount failure. The new partition erase code only triggers if the
auto-format also fails.
Hibernate (deep sleep) leaves the BQ25896 charger IC powered, drawing
~30-60uA quiescent from BAT. This adds a second option on the shutdown
page -- "power off" -- that writes the BATFET_DIS bit in BQ25896 REG09
to fully disconnect the battery from VSYS. Leakage drops to ~12-23uA
(IC internal only). Wake requires USB-C plug-in.
Shutdown page now shows two options with a cursor (up/down to toggle):
> hibernate: long press/Enter (T-Deck Pro)
power off: long press/Enter
> hibernate: long press (T5S3 / other)
power off: long press
Selecting "hibernate" triggers immediately (unchanged behaviour).
Selecting "power off" shows a confirmation prompt:
power off device?
usb-c to wake
Enter:yes q:no
Power-off display suppresses the header (node name, clock, battery)
and shows only "powering off..." and "plug in USB-C to turn on".
The 's' key shortcut to settings is gated on the shutdown page so it
passes through to the hibernate/power-off selection toggle instead.
Both the TCA8418 handler (loop) and the broader handler
(handleKeyboardInput) are gated via isHomeOnShutdownPage().
PRESS_LABEL macro: removed dead UI_HAS_JOYSTICK branch (no Meck
device has a joystick), collapsed to a single #define "long press".
Joystick input polling block in loop() also removed (dead code behind
#if UI_HAS_JOYSTICK, never compiled for any Meck build).
BQ25896 I2C sequence follows TI recommendation (E2E forum, Jeff/TI):
1. Read REG09
2. Write BATFET_DLY=1 (bit 3) -- delays disconnect so I2C completes
3. Write BATFET_DIS=1 | BATFET_DLY=1 (bits 5+3) -- last I2C write
The write happens after display turnOff but before board powerOff, so
I2C pull-ups on VDD3V3 are still alive. Board enters deep sleep, then
BATFET opens after tSM_DLY (~10-15s). Skipping the delay risks leaving
the BQ25896 I2C engine in an undefined state that can prevent wake on
USB-C plug-in (device soft-brick requiring battery disconnect).
REG09 bit map (confirmed from Linux kernel bq25890_charger.c):
Bit 7: FORCE_ICO
Bit 6: TMR2X_EN
Bit 5: BATFET_DIS (0x20) -- disconnect battery
Bit 4: JEITA_VSET
Bit 3: BATFET_DLY (0x08) -- delay before disconnect
Bit 2: BATFET_RST_EN (0x04) -- QON wake (not wired on T-Deck Pro)
Bit 1: PUMPX_UP
Bit 0: PUMPX_DN
Schematic confirms QON (pin 12) has R4 10K pull-up to REGN with no
user-accessible button -- USB-C is the only wake path from ship mode.
Guarded by #ifdef I2C_ADDR_BQ25896 so it compiles on all platforms
but only activates on boards with the charger (T-Deck Pro, T5S3).
Files changed:
UITask.h -- _full_poweroff, setFullPowerOff(), isHomeOnShutdownPage()
UITask.cpp -- shutdown page UI, input handling, BATFET write,
PRESS_LABEL cleanup, joystick removal
main.cpp -- 's' key gated on shutdown page (both handlers)
UITask shutdown (already occurs/unchanged):
1. BLE disabled (_serial->disable()).
2. WiFi disconnected + WIFI_OFF.
3. 4G modem shutdown().
4. GPS power cut (PIN_GPS_EN LOW).
5. LoRa radio powerOff() (standby mode).
6. Display turnOff().
TDeckBoard::powerOff() (new):
7. btStop() -- BLE controller stop.
8. Peripheral power OFF (PIN_PERF_POWERON LOW) -- keyboard, BQ27220, sensors.
9. LoRa module power OFF (P_LORA_EN LOW) -- cuts power entirely.
10. Hold LoRa NSS high (prevents SX1262 drawing current from floating CS).
11. esp_deep_sleep_start() -- CPU halts, ~10-40uA.
Wake (reset button or USB power-on):
12. ESP32-S3 cold boots.
13. TDeckBoard::begin() runs: peripheral power ON, I2C init, LoRa power ON, NSS hold released.
14. App starts fresh -- prefs/contacts/messages load from flash.
No LoRa wake during hibernate -- the device is truly off. Only a hardware
reset (reset button) or USB power-on wakes the device.
Incorporates hardware-specific learnings from caveman99's Meshtastic
T-Echo Card support PR (meshtastic/firmware#10267), cross-referenced
against LilyGo's official t_echo_card_config.h pinmap.
Battery (critical):
- Add BATTERY_MEASUREMENT_CONTROL pin P0.31 — gates the resistive
voltage divider feeding AIN0. Without toggling this pin, battery
ADC reads are invalid (floating divider input).
- TechoCardBoard::getBatteryVoltage() now drives P0.31 HIGH before
SAADC read and LOW after to avoid parasitic drain.
Display (critical):
- Add OLED_DISPLAY_OFFSET = 24 for the SSD1315 72×40 panel. The
physical display is mapped at GDDRAM pages 3–7 (rows 24–63);
SETDISPLAYOFFSET and SETMULTIPLEX commands are sent after
display.begin() in target.cpp to shift the visible window.
Power rail (high priority):
- RT9080 3V3 LDO now gets a clean HIGH→LOW→HIGH reset cycle with
100ms dwell in board.begin(), preventing brown-out when LoRa TX
fires at +22 dBm after a soft reset.
