I use windows 7 with all the drivers installed.
My PC recognise the Arduino Mega 2560 (Com port 20) and show the device as working. When I try to connect, the connection times out with the message:" No heatbeat packets received" The baud rate is correct 115200 as well as the com port. I have tried to connect after the GPS got a lock, it did not help.
Please help
