» 900HP 08a: Complete example TX

This example shows how to send a packet using unicast 64-bit destination address. After sending the packet, Waspmote waits for the response of the receiver and prints all available information

Required Materials

1 x Waspmote
1 x Battery
1 x MicroUSB wire
1 x XBee-PRO 900HP

Notes

- The battery has to be connected.
- This example can be executed in Waspmote v15
