[FOSS-GPS] RTKlib begginer's question

[oddpost]

Thanks. I was trying to enable ublox raw data from the gps chip, but got stuck at some point.
1. cat /dev/ttySAC1 gives NMEA without problems 

$GPTXT,01,01,02,u-blox ag - www.u-blox.com*50
$GPTXT,01,01,02,ANTARIS ATR062x HW 80040001*26
$GPTXT,01,01,02,ROM CORE       5.00    Jan 09 2006 12:00:00*76
$GPTXT,01,01,02,LIC 1EBF-BD07-E83D-6BE1-0F7A*50
$GPRMC,,V,,,,,,,,,,N*53
$GPVTG,,,,,,,,,N*30

2. but after set-nmea.py on and enable-raw.py are used, there are no any data 
goes to /dev/ttySAC1 at all.

I cannot understand what exactly i am doing wrong.
Would appreciate your help.

root at om-gta02:~/ubx# ./set-nmea.py off
callback ['CFG-PRT', [{}, {'Baudrate': 9600, 'PortID': 1, 'Flags': 0, 'Mode': 526544, 'In_proto_mask': 7, 'Out_proto_mask': 3}]]
callback ['ACK-ACK', [{'MsgID': 0, 'ClsID': 6}]]
root at om-gta02:~/ubx# ./enable-raw.py
 
Thanks
