I tried to using Novatel GPS OEM617 on Jetson TX1.
So I installed USB driver from http://www.novatel.com/assets/Documents/Downloads/ngpsusbpackage.tar.gz
It seems that the USB driver has been installed well (I’m not sure), because when I type ‘dmesg|grep tty’ then terminal says something to the effect of :
'ngpsser converter now attached to ttyUSB0
ngpsser converter now attached to ttyUSB1
ngpsser converter now attached to ttyUSB2’
And Opening serial port with serial terminal program (I used cutecom and python with pyserial) works very well.
But the problem is: After opening the port, I tried to serial write to or read from Novatel GPS device but it never responded.
And oddly enough, if I open the serial port just when GPS device turned on and finished the boot sequence, serial writing and reading is working well without any problems .
Of course, if I open the serial port except at that time, the opening process looks fine but serial writing/reading is not working.
I also tried that above with Windows and Ubuntu desktop both, but this mess is only on Jetson TX1.
Is this driver problem? or from another?
And how can I handle this USB serial communication problem?
I hope someone could help this matter.
Thanks in advance :)
