Hi, at the moment I try to understand how XBee works. I have one XBee connected to the computer and one is wired just to send back (in transparent mode) everything it recieves (hard-wire connection between DIN and DOUT). This is how far I got: I put the XBee coordinator (connected to my computer) in transparent mode. Now everything I type into my terminal ist coming back. So long it works fine. Next step: I put my computer-connected coordinator in API mode (1). The remote XBee stays in transparent mode. Now I send this package via terminal to my coordinator (all hex): 7E 00 16 //lenght 10 //send data 01 00 00 00 00 00 00 FF FF // to every XBee in my network FF FE 00 00 54 78 44 61 74 61 30 41 // my data to be sent C3 // checksum but… nothing happens. (Of course I tried to modify my API package). Where is my mistake? Sebastian ---

Hello Sebastian, Frame type 0x10 is not supported in XBee Series 1 (802.15.4), that frame type is for XBee Series 2 (ZigBee). Find here an API frame generator. The API frames to send in Series 1 are 0x00 and 0x01. If that is not the problem, please be more explicit on what module, firmware and version are you referring to (use X-CTU for reading settings). Best regards, ---

Yes! That’s it. Thanks a lot.
