need to change Xbee config on the fly

Wireless & IoT

Hello all,

I have a simple project where arduino is connected with a Xbee module (AT mode).

what I need to do is change parameters of xbee via arduino. for example let’s say I want to change PAN ID

i have tried following following things but to no avail

Serial.print ("+++");
delay(100);                               // different values from 10 to 500ms
Serial.println ("ATID 3");
delay(100);                               // different values from 10 to 500ms
Serial.println("ATWR");
delay(100);                               // different values from 10 to 500ms

Would highly appreciate if some one could provide me with a working code.

cheers

you can change settings in the XBee on the fly by either

  1. use the AT commands with the +++ escape. Read about that in their manual. Essentially, via the serial port, you pause 1 second, send +++ with no CR, then wait for the OK. This is like the Hayes modem protocol THen you send one of the many AT commands. Your code lacks the delay before +++ called guard time in the XBee manual.

As I recall, it’s ATID=3. Try it using a PC terminal program and serial port connection.

  1. Implement the complicated binary API mode for the XBee. This is more flexible if you want to do complicated things. For one, you can send AT commands to a remote radio.

Of course, you know that Digi’s XCTU utility can configure the XBees as you wish.

thank you Stevech. I’ll give it a shot
