The XBee 3 BLU device offers a configurable setting, BP (Bluetooth® Power), which allows you to control the transmit power used for Bluetooth® advertisement messages. Adjusting this setting can help optimize energy consumption depending on your application’s needs. Lowering the transmit power reduces energy usage but may also shorten the Bluetooth® advertisement range. The available power levels of the BP (Bluetooth® Power) setting are:

  • -20 dBm

  • -10 dBm

  • 0 dBm

  • 8 dBm (default)

By selecting a lower transmit power (e.g., -20 dBm or -10 dBm), you can save energy, especially in applications where Bluetooth® advertisement range is less critical. Conversely, higher power settings (0 dBm or 8 dBm) provide a stronger signal but at the cost of increased power consumption.
