 Some of the key capabilities of Portenta's Machine Control onboard Wi-Fi® module are the following:
 
 - **Wireless connectivity**: The onboard Wi-Fi® module supports IEEE 802.11b/g/n Wi-Fi® standards, enabling devices to establish reliable and high-speed wireless connections to access the Internet and communicate with other devices.
 - **Secure communication**: The onboard module incorporates various security protocols such as WEP, WPA, WPA2, and WPA3, ensuring robust data encryption and protection against unauthorized access during wireless communication.
-- **Antenna connector**: Portenta Machine Control devices feature an onboard vertical SMA antenna connector (5-1814832-2) specifically matched for the onboard Wi-Fi® module RF requirements.

 To enable Bluetooth® communication on the Portenta Machine Control, you can use the [ArduinoBLE library](https://github.com/arduino-libraries/ArduinoBLE). Let's use an example code demonstrating some of the capabilities of Poternta's Machine Control Bluetooth® module. Here is an example of how to use the `ArduinoBLE` library to create a temperature monitor application:
