I am using two XBee S2C(XB24C family) with ZIGBEE TH Reg function set, and Firmware version 405F.
I have set both of them in API2 and Router role(CE = 0).
I am using Frame type 0x17 along with 64-bit destination address and IS AT command to read ADC1 value off the other XBee successfully.
Now, Even though I have set the following parameters to their minimum values, I am still able to read ADC1 value off the other XBee over 15 meters:
NH = 1, BH = 1, PL = 0, PM = 0 for both XBees.
I know it is an unusual question, but how can I reduce the communication distance to the minimum through Radio Configuration? I don't want to use any shielding technique, but just a solution by making changes to Radio Configuration.
