disabling the GPS PPS about diy-tracker HOT 9 OPEN

from diy-tracker.

I just realized that the OGN receiver automatically change the RF frequency center to the Australia region (915Mhz) based on my location. that's why the receiver can not listen to the device. First, I though it was the gps problem. Now I have to find out how to change the center frequency back to 868.3MHz

I'm in Indonesia, and planning to use 868MHz instead of Australia region freq

OK, in the OGN receiver you need to set the FreqPlan=1; in the RF section like this:

RF:
{ FreqPlan = 1;
} ;

in the OGN-Tracker code, I have to think yet, how to do it best.
Is 868MHz the official band for Indonesia ?

BTW: to exclude the PPS code from the ESP32 OGN-Tracker comment out the line in the hal.h

#define WITH_GPS_PPS

from diy-tracker.

OK, to force a given frequency plan in the OGN Tracker please do the following:
in proc.cpp remove the like:

  RF_FreqPlan.setPlan(Position->Latitude, Position->Longitude);     // set the frequency plan according to the GPS position

In rf.cpp change the line:

RF_FreqPlan.setPlan(0); // 1 = Europe/Africa, 2 = USA/CA, 3 = Australia and South America

to:

RF_FreqPlan.setPlan(1);

Yes, in Indonesia we are using 868mhz.

thank you pjalocha, will try it to set the fixed freqplan

i have added the parameter FreqPlan to the STM32 and ESP32 OGN-Tracker so that you can override the automatic setting based on the location. For 868MHz send this to the console:

$POGNS,FreqPlan=1

the parameters are stored in the flash thus the Tracker remembers them after a reset or re-power.

thank you pjalocha. I will try it
