I'm having this exactly same problem...
Tomorrow I'll plug an LCD display to see what my xbee is receiving because it's
not a TX_STATUS package.

it's not a defect, it's a documentation and error on example code. You HAVE to
set frame_id > 0 or you don't receive an ACK from receiver.

Tx16Request defaults to frame id 1 (#define DEFAULT_FRAME_ID 1), which sends
an ACK, so this would never occur unless you explicitly set the frame id to 0.

I am experiencing the same problem. I am using the Series 2 xbee modules (ZNET
2.5 coordinator and end points in API mode). The packets (sent by the end
point) are received by the coordinator but the coordinator does not send an
ACK. I have not explicitly set the frame ID, I went through all of my code and
your code and see that what you have mentioned above is in fact correct (about
the defined DEFAULT_FRAME_ID 1).
I also went barebones back to your example and the packet sent by the end point
is this:
7E 00 24 95 00 7D 33 A2 00 40 2C 7C E1 00 01 02 00 01 00 7D 33 A2 00 40 2C 7C
E1 4E 4F 44 45 31 00 00 00 02 03 C1 05 10 1E 1A
Indeed the 5th byte is 00, which is the frame ID. There is definitely a bug
here.

I have now tried to hard program the frameID into XBeeRequest as follows, but I
still get the frameId as 00?
XBeeRequest::XBeeRequest(uint8_t apiId, uint8_t frameId) {
_apiId = apiId;
_frameId = 1;
}
I have now reverted this change, so would appreciate knowing what the
documentation error might be? I really need this to work for me.
Cheers guys.

There are a couple issues here. First, this issue concerns Series 1. The
series 1 code won't work for series 2. Second issue, the packet you provided
is API ID 0x95 (4th byte). This is ZNET_IO_NODE_IDENTIFIER_RESPONSE, so not a
TX request.

Delving further into it and realising my error, I looked at the UART on the TX
and it is in fact correct:
7E 00 10 10 01 00 00 00 00 00 00 00 00 FF FE 00 00 06 06 E5
which is a TX request to the Coordinator (0x00000000, 0x00000000) (FFFE) with
FrameID = 1 (ACK requested)
The UART at the RX end outputs the RX PACKET:
7E 00 0E 90 00 7D 33 A2 00 40 2C 7C E1 33 A5 01 06 06 0C
which looks correct and suggests that it has sent the ack (01 before the 06 06
payload).
The problem is that the end point times out waiting for the response from the
Coordinator (UART is silent), no matter how long I set the ReadPacket timeout.
Is there a setting somewhere that I needed to enable/disable to get this ACK?
Is it possible that I have a hardware problem?
I couldn't find any hint in the digi manual as the ACK should be at the MAC
level. Am now completely lost.
I very much appreciate your help and hard work.

I am experiencing very similar problems.
The two XBee v2 modules communicate and data is flowing from tx to the remote
rx modules. The communication on the transmitter side when viewed on the UART
is:
7E 00 29 10 01 ...
And on the the recieving side:
7E 00 29 90 00 ...
According to the documentation if frameID is 1 then ACK should be sent, but
none recieved. I increased the timeout from 500 in the sample code to 2000 with
no success. Is there anything need to be done in order to get the ACK back?
