I ran around the message board and google to figure out this problem. no avail.
- I have to move the device to a new COM port every time I boot it up
- When the GPRS shield starts up it spits out YYYYYYY like for other people
- After spitting out the Ys it does NOT proceed any further.
I have used a few different sketches that pass soft serial data, all produce the same error.
I have an arduino UNO R3 and the GPRS shield 1.4 from seeed
