CC1350: Low Radio Coverage cc1350sensorTag-Contiki 3.0-6LowPan-6lbr

Part Number:CC1350

Dear all,

I did a communication between two devices:

1.slip-radio(Launchpad cc1350)

2.Radio Node(Sensortag cc1350)

3.BBB connected to Slip-radio

I noticed that despite I put nullrdc_driver in the project.conf.h of radio node the radio coverage is only about 4 meters.

How can I do to increase the radio coverage of the systemn until 50 meters?

Are there others parameters to update ?

Any suggestions?

Thank in advance.
