如何调整蓝牙传输输出功率

I use DA14682 chip，and i use DA1468x_DSPS_v_1.160.2 SDK

help me please~

The document（DA14682_BA_FS.book） is say : 0 dBm transmit output power and -94 dBm receiver sensitivity (BLE)

How do I set the Bluetooth transmit power in the program?

I didn't find any function in the SDK to set the transmit output power.

I want to increase the Bluetooth transmit power to use it at a greater distance.

If I can't increase the Bluetooth usage distance by adjusting the Bluetooth transmit power, what methods can I use to increase the Bluetooth usage range?

thanks very much！

Hi,

The DA1468x family uses a fixed RF output power of 0dBm. You can add an RF front end to extend the range as demonstrated in our range extender reference designs://www.xmece.com/products/connectivity/bluetooth-low-energy/smartbond-reference-designs/range-extender
