L76 - How to use EASY Technology?

With EASY function enabled, the L76 will calculate and predict orbit information automatically up to 3 days to speed up positioning. The EASY function is enabled by default in L76.

After 3 days, what should I do to keep the information inside L76 up-to-date for EASY function?

My application need to put the L76 into backup mode frequently for power saving. How to know if EASY function is ready or not?

Hi Kiku,

1.Module need 5 mins at least to download predict orbit data from satellites after getting fixed.
After 3 days, please wait for 5 mins after module gets fixed, module will save new predict orbit information automatically.
2. EASY is enabled by default, and should be working when pin 6 V_BCKP(backup power) is on always and NMEA output frequency should be 1Hz.

Hi Sammy,

Instead of counting the number of days after position get fixed, can I use “Packet Type: 869 PMTK_EASY_ENABLE” to check the EASY function status? If EASY function is enabled and is not finished, wait until EASY function has finished before entering backup mode.

Hi Kiku,

Yes, you could use MTK869 command to check EASY status.
To query if EASY is enabled or disabled, use
$PMTK869,029
If EASY is disabled, the receiver returns
$PMTK869,2,0,0
37
If EASY is enabled and is not finished yet, the receiver may returns
$PMTK869,2,1,02A
If EASY is enabled and is finished 1-day extension, the receiver may returns
$PMTK869,2,1,1
2B
If EASY is enabled and is finished 2-day extension, the receiver may returns
$PMTK869,2,1,228
If EASY is enabled and is finished 3-day extension, the receiver may returns
$PMTK869,2,1,3
