Can the onboard 2.4GHz antenna be replaced?

The 2.4GHz antenna is a spring antenna, and there is no additional interface on the board for 2.4GHz wireless signals.

Can WiFi and Bluetooth be used at the same time?

No, Heltec V3 don’t have an external PSRAM, if your application need use Bluetooth and Wi-Fi at the same time, you can look into this product: Heltec Wireless Bridge.

What development methods does it support?

1. Arduino; 2. Micro Python; 3. Platform.io; 4. Espressif IDE; We strongly recommend using Arduino. We have complete technical support and provide complete LoRaWAN code for ESP32 Arduino framework.

Meshtastic screen has a digital front-end issue?

It’s caused by the meshtastic setting. Changing the default screen to SSD1306 can solve the problem. The specific steps are as follows: “Radio configuration”→”Display”→”Override OLED auto-detect”→”SSD1306”

It does not indicate device damage. Please disregard this phenomenon. The LORA ERROR occurs because it is running the factory default LORA testing program and cannot find another device running the same program.
