I'm trying to calibrate my compass offsets using xbees for the communication. Everytime I get the menu in the CLI it cuts off around line r
r - Reset to fa
And when I use c to do compass offsets it streams the numbers for about 15-30 seconds and then stops and the IMU instead of walking red orange green it stays solid green?
Does this mean the IMU has crashed? I can only restart it to get it back and also have to debrick the xbee also because it seems to get corrupted in the process.
I think you likely need to increase the baud rate of the xbee. The CLI menu is displayed all at once so it's a reasonably large amount of text that needs to get through the Xbee in a short period of time. I think what's happening here is that the outboard buffer on the APM is filling up. Sorry, I'm not sure if the APM crashes when the buffer overflows (I hope not)
Personally I've never used the XBee to do configuration although i believe many others have.
I always set the xbees to 115k. Is that the right rate?
When the IMU is in CLI mode (walking leds) and it stops and displays solid green, does that indicate it's crashed?
Also when I pull the battery and restart, (before connecting the blue xbee wire, to avoid bricking it) the blue and red lights flicker until I plug in the blue wire and then the red and blue stay on and I have to debrick it.
The reason I was wanting to do the magneto configuration wirelessly is so I can spin it around without risking pulling out the usb cable. Most people are doing it via usb?
I received at the end of March a HMC5843 - Triple Axis Magnetometer Rev 1.2
Do you know if this has the noise issue resolved? The last one i had to remove the little resistor but this time I soldered it to the IMU and forgot to check first. :-/
Is 1.2 ok? It's the latest version?
The noise issues were resolved within days of that post from Jordi going up saying they'd found a problem. That was months ago and I haven't heard any compliant so I think it's all a-ok. I've personally ordered two mags since that time and they're working beautifully.
Hi Bones :)
The mag output does the turn. I'm not touching the left stick. I can be flying in perfectly calm space and it will twitch to the right and then go back. If I fly circles without touching the yaw stick, it will stay straight so it always recorrects itself.
One thing that I'm not sure about is on my transmitter (JR9503) I can't leave the trim centered on the yaw. If I center it then it slowly turns in that directly just like if I was not using the magnetometer. That part makes sense since it's trimmed in that direction but why does it NEED to be trimmed off center? Does that mean I need to redo my accelerometer offsets? I used CLI on a level surface when I did it and when I turn on the copter, I try to keep it as still as possible because I understand that can cause some error in leveling if you turn on the quad so that it initializes with the copter not stable.
