T-Beam

Is this bug report about any UI component firmware like InkHUD or Meshtatic UI (MUI)?

• Meshtastic UI aka MUI colorTFT
• InkHUD ePaper
• OLED slide UI on any display

Firmware Version

2.7.15.567b8ea

Description

LiliGo T-Beam consumes 89+% of the heap just after start if WIFI/MQTT is enabled. I tried to reflash with full erase (as some report suggests) and reset node db but it does not have any visible impact.

Some tests (measure done after start with emty nodedb):

1. Device with WIFI disabled: 61% of the HEAP in use
2. Device with WIFI enabled but MQTT disabled: 85%
3. Device with both WIFI and MQTT enabled: 93% (nodes are fetched from MQTT)

I'm not sure if it is expected behavior, so I decided to report. Also, I found that PSRAM is not in use at all.
