Expanding ESP32 connectivity beyond Wi-Fi and BLE
We have already explored ESP32 Wi-Fi and BLE capabilities. While the built-in Wi-Fi and BLE capabilities of the ESP32 offer robust connectivity options, there are scenarios where these technologies alone may not suffice:
- Remote and disconnected areas: In remote or rural areas with limited Wi-Fi infrastructure, establishing a reliable internet connection can be challenging. Here, cellular communication comes to the rescue.
- Long-range communication: While Wi-Fi and BLE are suitable for short-range communication, they may not be ideal for applications requiring long-range connectivity.
- Contactless and close proximity interaction: In scenarios where physical contact or proximity is not feasible, NFC presents an excellent option.
In each of these scenarios, the ESP32, when combined with additional communication modules, can overcome the limitations of Wi-Fi and BLE and enable connectivity in diverse and challenging...
