Re: Android App connection error

Working now! To recap, On the phone , Mobile (Cellular) Data needs to be OFF GPS position : Even if Google Maps shows a position inside a building, the phone needs a clear view of the sky.

Re: Android App connection error

I tried a co-worker's Android (Version 8.0) and the App is working fine (Accurate position and DOA value showing).

Android App connection error

I'm able to connect wirelessly to my tinkerbooard to play with the compass but the KerberosSDR app always shows my position in New Zealand (I'm in Canada) :lol:

Also, enabling the DOA results in a 'Error occurred for udating DOA value.'

Re: 90 deg and Sample Size

:?: Hum...playing with the sample size boxe I do see a change, If I leave it at the defaulted 15 the Compass is very fast and point in many directions and at 5 is moving more slowly and less prone to wrong readings.

Re: Share your results

This is the calculation i've used:
Freq of 925MHz @ 1/1 = 32.4cm x 0.3535 = 11.45cm

From this drawing, between antennas 4 and 2 I have 22.90cm (2x 11.45cm)

Using dipole antennas on a 50x50cm ground plane.

90 deg and Sample Size

Can someone explain the "Calibrate 90 deg" button under the DOA Estimation tab.

Also, under the same tab, the "Sample Size" box is missing from the web page.

Thanks all!
