Hi All,
I am new to the arduino forum. I have couple of questions with ethenet shield (w5100). I am using Xbee (for zigbee) on the top of ethernet shield. I am able to send ethernet (UDP/IP)data through xbee wirelessly.
Here is my problem. This is working like a charm when I am using STATIC IP address. But when I configure my arduino as DHCP it is not working anymore.
The library for DHCP is here...http://gkaindl.com/software/arduino-ethernet/dhcp
If I use methods from xbee.h and ethernetDHCP.h simultaneously it hangs arduino.
Is there anybody here who has use DHCP with ethernet shield with Xbee?
I am using arduino Duemilanove(who has one serial) and Xbee PRO series 2 and ethernet shield Wiznet W5100.
Here is a some part of my code which is working fine. But When I use xbee methods like
XBeeAddress64 addr64 = XBeeAddress64(0x0013a200, 0x407a94e0);
ZBTxRequest zbTx = ZBTxRequest(addr64, payload, sizeof(payload));
ZBTxRequest zbTx1 = ZBTxRequest(addr64, payload1, sizeof(payload1)); (This 3 line of code is at the beginning of void setup{ })
it just hangs.
