It’s been a while since the last time I can pick up the Mono for a test.
When I powered it up, the first thing that I saw was that the GPS reverted to the original code, going back to 9600. I couldn’t resolve this issue. I flash it with the code and save the config (which was the step that I have been missing when I first started) it works at 115200 baud rate, communicating with the I2C board. Then I power it off and if I power it on soon after, no problems. It works. But if it waits for a couple of days, it reverts back to 9600 baud and needs to be re-flashed. If anyone has some useful advice on this I would love to listen.
After re-flashing it and getting the GPS to work, took it up. These days it is very windy and I don’t want to test it in strong wind but I didn’t have an option as this is my only available time. Before the flight, you will see the baro kicking in as I holding it, moving it up and down.
During the flight the baro&GPS combination were activated multiple times. First one minute or so, I am trying to trim the unit to get it to stabilize a little bit. The first baro&GPS activation was at 2:10 minute mark and the unit lost altitude pretty fast, causing me to de-activate them right away. The second activation is at 3 minute mark and a couple of more times after that. You can hear the fan adjusting to compensate when I activate it. However, this test was more challenging than my first one last a couple of weeks ago, as the unit slowly lost altitude this time, with the fan kicking in and out in a rough manner. I didn’t change the settings, but that day there was no wind at all. I believe this is the difference. The sensor is affected by the wind. So, I will need to cover the controller and test it again, to see if it fixes that problem.
When it comes to GPS, I kinda felt some added stability when I activated it but the unit still moved slovly with the wind. So, I will have to make some PID changes on that. I was able to connect to the FC via Bluetooth and my phone, which will make it very convenient to test in the field with various settings.
I would appreciate any tested valuable methodology on how to set the PID for GPS and Baro, as I have never tried those before.
