Hi Libelium,
I am not that sure about how OTAP work still. The sample code even in the waspmote, the code should be uploaded to the end device, am i right?
Do I need to upload any code to my coordinator?

I have tried scanning, the result I got was

Code:

Total Nodes: 0 - Time elapsed: 10s

May I know which part of it is wrong?

Using X-CTU, make sure your Gateway is configured to use API=1 and your waspmotes to use API=2. Also make sure that they use the same channel and have the same PAN ID. Then make sure these match up with what you have set in your xbee.conf file.

Hi Fab4,
I still encounter the same problem after I changed the API.

I have a question about the PAN ID. It says that, the PAN ID is 0xFFFF, so I need to use the first 4 digit or the last 4 digit for my PAN ID.

My channel is C, does it matter that i put C instead of 12?

I have a question about the SD card too. Do I need to insert the SD card? Insert into my end device or coordinator?

tyvm!

Hi,

First of all you must make sure taht allt your XBee modules have the same configuration. In case you use XBee ZB modules, you must keep in mind that routers and end devices connect to the coordinator, so it is not that easy to connect all of them together. Are you sure about this first step?

Best regards
