• • • 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 Bluetooth be used at the same time?

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

    • What development methods does it support?

      -Arduino;

      -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”
