TTFF not calculated (Position not fixed) BUSY


#1

Hi there ,
I was trying get the GPS data (using wp7502) and following is the flow i followed
-> root@swi-mdm9x15:~# gnss start
Success!

-> root@swi-mdm9x15:~# gnss get date
Position not fixed. Try ‘gnss fix’ to fix position

-> root@swi-mdm9x15:~# gnss fix
TTFF not calculated (Position not fixed) BUSY
TTFF not calculated (Position not fixed) BUSY
and with AT commands i have this

–> AT!GPSSATINFO?
Satellites in view: 2 (2019 01 11 4 05:46:52)

  • SV: 1 ELEV: 19 AZI: 309 SNR: 24
  • SV: 18 ELEV: 38 AZI: 281 SNR: 30
    –> AT!GPSSTATUS?
    Current time: 2019 01 11 4 05:48:04

2019 01 11 4 05:45:49 Last Fix Status = FAIL, FAILCODE = 12
2019 01 11 4 05:45:50 Fix Session Status = ACTIVE

Please let me know what is the issue and a solution to overcome this ?

Think you need at least 4 satellites in view to get a fix.
Check your antenna and make sure it has a clear view of the sky.
