No packet ACK on Coordinator

[garvamel]

Hello!
I'm connecting 2 Xbees with the examples Series2_Rx_Nss and Series2_Tx. Communication is working great, but I never get a positive ACK on the coordinator. On the end device, the delivery status returns "succesful". The relevant excerpt from the Series2_Rx example is:

      // got something
           
      if (xbee.getResponse().getApiId() == ZB_RX_RESPONSE) {
        // got a zb rx packet
        
        // now fill our zb rx class
        xbee.getResponse().getZBRxResponse(rx);
      
        nss.println("Got an rx packet!");
            
        if (rx.getOption() == ZB_PACKET_ACKNOWLEDGED) {
            // the sender got an ACK
            nss.println("Sender got and ACK");
        } else {
          nss.println("Sender didn't get an ACK");
        }

Which always prints "Sender didn't get an ACK". Any insight on this is much appreciated.

Thank you all in advance!

I'm an idiot for posting right before finding my mistake. The ACK validation had to be done against 0x41 and not 0x01 (ZB_PACKET_ACKNOWLEDGED). Because the message came from an End Device directly. Closed!
