Re: [gpsd-users] Changing the GPS update rate with gpsd

[Bernd Büchs]

Hello Deven,

sounds strange, when the Adafruit device has a coin battery it should keep 
this setting otherwise I would consider to replace the battery...

Back to you question you could put "echo ''$PMTK220,100*2F/r/n > /dev/<your 
interface>" in some bash script and start it before gpsd or even "hack" the 
gpsd starting script and put it there, in this case an update of gpsd package 
might overwrite your change...

Kind regards


Bernd
