To set up this application, complete the following steps:
Connect the WB50NBT (Device name: WB50 SPP-Socket) with another Bluetooth device using SPP (Serial
Port Profile).
Connect another network device to the WB50NBT on port 3000. For example, to connect a Linux machine
to the WB50, enter the following command, where xx.xx.xx.xx is the IP address of the WB50:
nc xx.xx.xx.xx 3000
Figure 5: SPP to Wi-Fi bridging structure
As soon as the WB50NBT has established both of these connections, data coming into either interface is echoed
out from the opposite interface. See the WB50 smartBASIC Extensions guide and the WB50NBT Reference Guide
for more information. These documents are available from the Documentation tab of the Laird
