I’m using three those trackers and work well but when trying to change GPS searching from default GPS only to GPS+Galileo+Glonas then got “Wrong parameter” response. I’m running current firmware 1.6.7 but same situation was in 1.6.4 as well.
The reason to change setting is speed-up fixing possition. Currently GPS fix tooks approx 60 second. I hope switching to use GPS+Galileo+Glonas can speed up fix to few seconds instead of minute or two.
Have you any hint for me, pls?
