802 09a: Expansion board TX

This example shows how to use two XBee modules simultaneously in Waspmote using the Expansion board. Two different objects are created in this code, each one is used for each module. One is connected in the standard socket (SOCKET0) and the other one is connected to the Expansion board (SOCKET1)

Required Materials

1 x Waspmote PRO 1 x Battery 1 x MiniUSB wire 2 x XBee-802.15.4 modules (2 emitter) 1 x Expansion Radio Board

Notes

- This example belongs to a two-code example. This is the sending part. - Both XBee modules must be configured with the same network parameters (PANID, channel, encryption mode) - The battery has to be connected. - This example can be executed in Waspmote v12 and Waspmote v15
