Does anyone know much about the S2B models?

The modem type shows up as XBP24BZ7 in X-CTU.

Low power ones work fine too. Just that I have got a bulk order and they are all the Pro S2B models.

Is the S2B necessarily the "programmable" type do you know? I am wondering if I should send back the ones I have bought and get the "non-programmable" ones.

Hi Jack,

Yes the sketch works fine as soon as I take the XBee off, and I have tried several shields/xbees/arduinos. I am also using external power so I don't think that should be a problem.

Does work in API mode but I am going to have to change alot of code to get that to work - which I would like to avoid!!

Actually one more strange thing is that it seems to work OK (even in AT mode) on a Twenty-Ten but I need it to work on the Eleven's I have bought.

Thanks for your replies!!

Hi thanks for the reply - I should have said that regardless of the code on the arduino the same thing happens.

If I get a new Arduino and Xbee out of the box, configure the XBee to End Device AT and plug it into the Ardunio via shield with external power, the D13 light does the flashing and the sketch won't run.  (Would be the 1 second D13 on/off sketch by default)

So I think it's independent of code and I am using the standard sparkfun XBee shield.

I have seen one other post with the same issue but no solution was given here:

I have just bought a whole bunch of Xbee Pro S2Bs and Freetronics Eleven boards.

When I set up the XBees in AT mode, the Arduino constantly resets.  At least that's what I think it is doing - the D13 LED keeps flashing (3 times in quick succession, once per second) and the sketch won't run.

In API Mode it seems fine, but I want to use AT mode for simplicity - anyone have any ideas why AT mode would be causing the Arduino to reset?
