LilyGO T-Deck Pro — 4G vs Voice version? Any firmware updates on touch lag?
Hey everyone, I'm about to pull the trigger on a T-Deck Pro and I'd love some advice from people who actually own one before I order.
My use case:
- Meshtastic off-grid messaging
- MQTT publishing via cellular (no Wi-Fi dependency)
- Connecting an M5Stack ENV III sensor (temperature, humidity, pressure via I2C/Qwiic)
- Programming with VS Code + PlatformIO (Arduino framework)
My main question: 4G (A7682E) or Voice (PCM5102A)?
The 4G version makes sense for my use case since I want to publish MQTT data directly over cellular without relying on any LoRa repeater or mesh node. But I've read that in the 4G version, audio is handled entirely by the A7682E modem rather than the ESP32-S3 — does this cause any real-world limitations I should be aware of?
Second question: touch screen lag — has it improved?
I've seen several reports of the touchscreen having a 5–6 second response delay. I know there was a community fix (T-Deck-Plus-TouchFix_241203.bin) but that seems to be for the T-Deck Plus, not the Pro. Has anyone confirmed whether this affects the T-Deck Pro as well? Is there a specific firmware version or patch that addresses it?
Third question: Meshtastic firmware status
I noticed the Meshtastic docs list the T-Deck Pro as supported, but has anyone actually been running it day-to-day? Any known issues with the current firmware build on the Pro specifically?
Any real-world experience is hugely appreciated — reviews online are pretty sparse for this device. Thanks!
