Hi to all

I have Arduino Ethernet and Seeeduino gprs module. When i connect board with gprs shield Ethernet don't run good, and a simple http client communication (Ethernet client example) it remain blocked. if i detach gprs shield , Ethernet run well and data flows from remote web server.
It is possible to resolve this problem, or it is possible to use another gprs shield (or serial module) compliant with Arduino Ethernet ?

Sounds like a pin conflict problem. What pins is the gprs shield using?

Hi

thank you for response

7,8 software serial, 9 on/off switch, but if i use other pins situation is the same. i notice that including "newsoftserial.h" blocks Ethernet library even without gprs board. Now i'm using mega 2560 with Ethernet shield and gprs shiled connected to one of additional serial channel (rx1/tx1) directly to gprs jumper switch by a cabled patch. it run good but sound like a trick...
