Optional Wi-Fi (DS1101 and DS1102 only)
The DS1101 and DS1102 can optionally accommodate the WA2000 Wi-Fi/BLE add-on module (letter "W" in the model numbering scheme). Only the Wi-Fi functionality of the WA2000 is supported by the DS1101 and DS1102. The WA2000 superseded the GA1000 Wi-Fi add-on module, which is now obsolete.
The following GPIO lines are used to control the WA2000 (GA1000):

- The "data out" line of the DS1101/2; connects to the "data in" on the WA2000 (GA1000).
- The "data in" line of the DS1101/2; connects to the "data out" on the WA2000 (GA1000).
Wi-Fi data communications are the responsibility of the sock. object. Before such data communications can take place, the Wi-Fi interface must be properly configured. This is jointly achieved by the wln. object and the WLN library.
Note that DS110x devices cannot accommodate the Wi-Fi and PoE options at the same time.
