BN-880 GPS Orientation

[wmyhal]

Im using the Tinygpsplusplus library on an ESP32
Currrently my BN-880 points north with wires on the right side of unit.

Is there a way to change the orientation so that north (0 deg) is on another side of unit?

Add 180 degrees to the compass reading it produces ?

[wmyhal]

Sorry im very good at this math.
Can you tell me how I add the 180 deg to it?
There must be a formula

[jremington]

Compass_reading = Compass_reading + 180;
if (Compass_reading > 360) Compass_reading = Compass_reading - 360;

[wmyhal]

That you
Ill give it a try

[wmyhal]

@jremington

Compass_reading = Compass_reading + 180;
if (Compass_reading > 360) Compass_reading = Compass_reading - 360;

Thanks guys
Works Perfect

One more question.
I am totaly new to programing a gps. My question is:
Do I need to calibrate the compass on the bn-880?

[Wiky5]

well, I'd suggest you read the documentation on it. Usually you can find most relevant information on the summary.

Do I need to calibrate the compass on the bn-880?

Yes, if it does not produce the expected headings, while you turn slowly around.
