Programming Arduino via xbee

Hello,

here my Hardware first:
Arduino UNO R3
Arduino XBee Zigbee Shield (the old one from Arduino)
Xbee Series 1

I have a connection from the PC to the Arduin over Xbee and can receive Seriell Data from the Uno.
But i can't programming the Arduino, after upload a sketch i receive this message:

Der Sketch verwendet 7.990 Bytes (24%) des Programmspeicherplatzes. Das Maximum sind 32.256 Bytes.
Globale Variablen verwenden 495 Bytes (24%) des dynamischen Speichers, 1.553 Bytes für lokale Variablen verbleiben. Das Maximum sind 2.048 Bytes.

any ideas what is wrong?

Hello,

I think I found the problem, i need the DTR line for the Arduino.
My solution i to send the DTR Signal by an i/o pin to arduino.
But i need a level shiffter for the Xbee out put to the Arduino Reset.

Can i use the CTS level shiffter on the Arduino Xbee Shield by connect DI0 to CTS?

Regards Thomas

Hi thomas

Did you solve hte problem. Actually I am having the same problem. I am trying to upload the code on the Arduino board using Xbee but the uploading is taking forever and I am getting the same sync error what you posted in your post.

Please help me and guide me.

sincerely

Sometimes the upload does not work because there is something connected to the serial pins (TX and RX) during the upload. I had that problem with my Arduino Nano. If your using a shield it may be better to disconnect it during the upload.
