Arduino Due

[edgargdl]

Hello ! i am having trouble for the past weeks trying to make this arduino Due work.

i have cut the jumper to make it work on 3.3 and I have manually wired from hardware serials to pin 10 and 11 ( cross wired Tx to Tx and Tx to Tx )

I can create a loop back between my hardware serials so I am sure the fue it’s sending the AT commands ( I am sending AT and the command to turn the light blue off of the network to test is it ever reaches the SIM module, but it never happens.

I was just adding the jumper on the top to the hardware serials but as that did not work I ended up wiring everything externally but same issues.

My approach now is thinking if I need to set up some sort of baud rate that matches the velocity of the hardware serial, but I made some loop backs and I can see that baud rate does need to match so I have everything to 19200 and I assume it should work like that.

i have also tried the auto baud rate setting it to 0, but that also did not work

I can not find a way to make the shield read my commands from the due, Hope you can help me I might post this in many channels as I am not sure where you are reading these days.

thanks a lot in advance
