Heltec Wireless Tracker 433 MHz - stuck with gpsEcoMode after first fix

[dnodar8-cell]

Firmware V2.4.3.2 version from 2026.04.22
Heltec freezes after first fix if gpsEcoMode is activated : screen black, retro light on, user button not responding (only reset button works)
Same with or without Display EcoMode ON or OFF
Tried with battery + connection to a usb power source (in case of low power issue)
Tried with gpsEcoMode not activated, tracker works (but battery last only a few hours)

Model
HTIT-Tracker (HELTEC)
433~510mhz

0.96"80x160 TFT

Hi, GPS ecoMode is still in development

on this specific board the GPS off turns off also the screen

so to turn on the screen press once the user button and it should turn on again , but as is still in development I recommend avoiding if this inst the expected results as behavior for you

as for the battery usage, use a bigger one ... esp32 + gps uses like 100mA more or less

In my case, user button does nothing when the board hangs, I will disable gpsEcoMode for now.
Thanks for your reply and congrats for the amazing work anyway !
