hi.. have anybody here tried using an mc55 gsm/gprs module? can you please show me how configure it to make it receive udp data packets? i have successfully make it send data to a computer server. but what i want to do is for the server to send data to the module. i believe that the problem is not on the server since i can send data from the server to another computer. is it necessary to create two profiles in the module? one for sending and another for receiving? please help...
