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 ESP32’s WiFi and Blue tooth be used at the same time?

No, the WiFi LoRa 32 don’t have an external PSRAM.

What development methods does it support?

-Ar duino;

-Micro Python;

-Platform.io;

-Espressif IDE.

We strongly recommend using Arduino. We 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”
