CC2538DK: CC2538DK

Part Number: CC2538DK


I know from datasheet that minimum tx power is -24 db which is equal to set the txpower register to 0x00.

I have done it in contiki by contiki function but still nodes can hear each other from the distance of almost 20 meters.

However, I need to reduce the tx power to almost 1 meter or less than that.

I tried to wrap the board with non-static plastic to reduce the tx power, it is reduced drastically (around 25 cm), but I face packet loss. even without that (wrapping) I have packet loss which is not suitable for my protocol.

I am doing my research in a place that there is no WiFi to interfere the signals, but still packet loss is bothering.

Could you please suggest me how I can do it?

It is very important and urgent for me.

Thanks so much in advance.
