» 900HP 12: Set power level

This program shows how to set the power level * of the XBee module. Possible values: * PL = 0 --> +7 dBm, (5 mW) * PL = 1 --> +15 dBm, (32 mW) * PL = 2 --> +18 dBm, (63 mW) * PL = 3 --> +21 dBm, (125 mW) * PL = 4 --> +24 dBm, (250 mW)

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
