FAQ

1.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.

2.Can ESP32’s WiFi and Bluetooth be used at the same time?

No, the WiFi LoRa 32 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.
