CC1312R: Wi-SUN FAN insufficient Range

Part Number: CC1312R


Hi, I hope everyone is doing fine.

I am trying to develop an smart meter application for which I am planning to use TI Wi-SUN FAN stack with CC1312R series.

I created a BR: border router(ns_br_src example) and RN: router node(ns_coap_node_src example) and able to communicate using spinel python script(controlling the Red led on RN).

The issue is I am unable to achieve communication range more than 100mtr(Method used for range testing is by sending "ping" command from BR to RN).

I am using example provided in TI SDK "simplelink_cc13xx_cc26xx_sdk_6_30_01_03" as it is with "CC1312R7 launchpad".

We are using the launchpad with PCB antenna.

Although I have updated the .syscfg file as follows:

  • Updated the Transmit Power to max --> 14dBm (on BR and RN)
  • Force VDDR --> Checked (on BR and RN)

May be I am missing something small here as Wi-SUN promised range is in kilometers.

It would be great help if someone can guide me to the right path.
