XBEE-PRO XB09-DP Firmware version 1002 Hardware version 1B42

In the documention for the TX Status packet (0x8B) (page 33), there are 8 possible return values for the Delivery Status byte.

I have seen only 0 (success) returned, and 1 (undocumented – but it happens when I turn off the remote radio). I tried to self-address a packet (sent it to myself) to see if that would result in a Delivery Status of 0x23 as indicated in the documentation, but 0 (Success) was returned instead.

Example: (self addressed)
