Hi all , I am working with gsm , gprs and xbee modules on Udoo, but not able to establish a serial communication between the devices, following are the modules i am using with udoo. 1. GPRS-GSM Quadband module for Arduino. 2. Digi International Xbee S1 ( Series 1). Tested the devices separately and was successfully able to establish serial communication with arduino due board. But not able to do the same on udoo's arduino due side.. If these modules work on arduino due board their must be no issue on working with udoo's arduino due side ??? right.... I Tried with all serial ports on udoo's arduino due side( tx n rx, tx3 n rx3, tx2 n rx2 , tx1 n rx1).. Any one hve worked with any of the modules on udoo, let me know and plz suggest solutions.... thank you,,
