Can't send commands with XCTU in API mode using XB24-Z7

Hello,

I don’t understand why sending API commands or data doesn’t work.

I use following parts/firmware:

2 XBEE Modems: XB24-Z7 CIT-004.
firmware Coordinator: 2164
firmware Router: 2364

First of all, I’ve got this frame:

7E 00 0F 10 01 00 13 A2 00 40 68 72 E9 00 00 00 00 31 05

7E start delimiter
00 0F length
10 API Command Frame id for transmit request
01 frame id
00 13 A2 00 64-bit address of Coordinator high
40 68 72 E9 64-bit address of Coordinator low
00 00 16-bit address of Coordinator
00 Broadcast radius max, has to be 0
00 Options must be 0x00
31 data bit 0x31 for ‘1’
05 Checksum

When sendig the frame via ARM7 µC to Din ofXBee I can receive the char on Coordinator`s XCTU (or with HTerm)

But when typing this command in the Router´s Assemble Packet or direct in the HTerm Input section no char is transmitted.

When I try to send in the opposite direction from Coordinator to Router the following frame:

7E 00 0F 10 01 00 13 A2 00 40 68 73 D4 CE 26 00 00 31 2A

(instead of 64-bit and 16-bit address of Coordinator now the addresses of Router and the checksum changed)

no char transmitted, nither to XCTU nor to HTerm.

When working in AT mode I succeded with
+++
ATCH
and
+++
ATD5 0 (or 1 respectively)

But sending the correspondig frame for the CH Request
7E 00 10 17 01 00 13 A2 00 40 68 72 E9 00 00 00 00 4D 59 89
doesn´t work.

Please can someone help!

Thanks a lot!

The frame what you are sending is incorrect. i.e.,
7E 00 10 17 01 00 13 A2 00 40 68 72 E9 00 00 00 00 4D 59 89
Use the following frame maker link to build the frame, http://ftp1.digi.com/support/utilities/digi_apiframes2.htm
Provide the required values and then hit “Build Packet”.
