I know you are experienced but could you check if the data is coming till xbee module using virtual port simulator
or you cable is reversed
---------- Post added at 23:17 ---------- Previous post was at 23:17 ----------
try to check the baud rate of both the modules toooo
According to you i have to change destination and source address..If I remember correctly, to use Xbee modules are serial replacement, you need to set each module so that local DL/DH matches remote SL/SH.
In configuration both pan id are 0You have to configurethe XBEE's on the same PAN and then program one like a coordinator (i.e.) and the other only change the Network address to 2, that's the easiest way
According to you i have to change destination and source address..
at present destination and source address all are same 0000
When operating in transparent mode, the modules act as a serial line replacement. All UART data
received through the DIN pin is queued up for RF transmission. When RF data is received, the data
is sent out through the DOUT pin. The module configuration parameters are configured using the
AT command mode interface.
Data is buffered in the serial receive buffer until one of the following causes the data to be
packetized and transmitted:
• No serial characters are received for the amount of time determined by the RO (Packetization
Timeout) parameter. If RO = 0, packetization begins when a character is received.
• The Command Mode Sequence (GT + CC + GT) is received. Any character buffered in the
serial receive buffer before the sequence is transmitted.
• The maximum number of characters that will fit in an RF packet is received
RF modules that contain the following firmware versions will support Transparent Mode:
20xx (AT coordinator), 22xx (AT router), and 28xx (AT end device).
The Test / Query button is used to test the selected COM port and PC settings. If the settings and COM port are correct, you will receive a response similar to the one depicted in Figure 4 below.
I assume you have the baud rate, word size, etc correct (garbage data is a classic symptom of incorrect baud rate) ? if it is OK could you be sending characters faster than the receiver can process them and you are getting data overruns etc?
