Both the Meadow development board and production module have an onboard ceramic chip antenna and a U.FL connector for an external antenna for the 2.4GHz WiFi and Bluetooth radio. Additionally, there is an antenna switch for switching between the two; by default, the chip antenna is selected, and you must use the Meadow.OS device API to switch to the external antenna.

Determining the Currently Selected Antenna

The current antenna in use is available via the device’s CurrentAntenna property. For example, the following code will write which antenna is currently in use to the console output:

Console.WriteLine($"Current antenna in use: {Device.CurrentAntenna}");

Switching the Antenna

Likewise, switching the antenna is also available via the device. Use the SetAntenna() method to change the current antenna:

Device.SetAntenna(AntennaType.External);
