I promised myself that I wouldn't take my FR apart again until it was
time to install the GTA04 board so I won't have pics of what I did this
weekend, but I can share some other info.

Very helpful. Can you provide schematics as a attachment to list, or as
a link?

I'm struggling to understand what you've done, but ity sounds like something
I'd be very please to have.

Dusting off a very old thread...
I have both of my sensors working and good gps performance now.
This weekend I opened the position settings->satellite details dialog in
SHR as well as my phone and tried a few things. I was seeing serious
signal loss as soon as I connected the SCL line from t
Given the performance degradation in GPS lock cause by high SD drive
strength and the i2c being on flying leads right next to the antenna I
certainly wouldn't rule it out.

Hi
You can try to add a series resistor to the signals or reducing the drive
strength of the driver.
The frequency of the signals are not that important but rather the rise
time.
This is usually not a problem om i2c but who knows.

Hi,
Ferrite beads aid with removing VHF-SHF feedback and/or uncontrolled
oscillation mainly. I cannot see why they would be of use on a (500khz?)
I2C bus. At that frequency they would have minimal effect.

With the i2c devices removed, I get TTFF of around 1 minute in
shr-core. It sounds like putting ferrite beads on SDA and SCL might
help reduce EMI, so I will try that when I get a chance.

Hi Ben
Not sure this is relevent to you, but I now have the fastest GPS fix I've ever
had on the freerunner.
QTMoko v35 and I put this in /etc/default/gpsd:-
START_DAEMON="true"
GPSD_OPTIONS=""
DEVICES="/dev/ttySAC1"
USBAUTO="false"
G
For months now I have had poor performance with my Freerunner's GPS.
The GPS problems did not seem to coincide with the two times I have
opened my Freerunner to add I2C sensors. I have an infrared thermometer
and a barometer.
Lately I have missed the GPS enough to look into the issue more.
