GPS

Antaris4 receiver from U-BLOX, uses /dev/ser2 :

The vdev-flexgps checked UBX buffer limit (0x100=256 bytes) is too low for the RXM-RAW message (max size: 8+16*24+6=398bytes). Here is an example of an error message for the 13 visible satellites (0x140=320=8+13*24)

GSM

GSM/GPRS modem Cinterion AC 75] on /dev/serfpga2.

pppd for QNX-SH4 is missing. It should be possible to receive the RTCM messages for RTK or submit the current location and GSM CID/LAC (AT+CREG=2,AT^MONI,AT^MONP,AT^SMONG) over GPRS to a tracking server.

NDR

Started with:

To init the raw GPS data output it may be possible to use /dev/ndr/cmd (format unknown), or just push the raw UbloxRAW commands directly to /dev/ser2.

The debug interface may be used for logging raw data in ASCII hexdump form:
