Daughter Board connections got loose!

I've already noticed that my GPS light won't come on at times last week, so I re-seat the daughter board and solder up the power pins.  Today, my heli did some sudden 90 degree yaw turns.  I later looked at the tlog, and there were no mx,my,mz data.  I then looked at the live tuning data and confirmed that some of the 12 pins connections to my daughter board was loose.

I removed the daughter board from the APM2 and bend the data pins a little and put it back in.  Let's see if it hold.

  • Wesley, the sudden yaw turns, were they to the south?

    I'm wondering if, when the magnetometer lost comms with the Atmega, did the code know there was a failure and then ignore the mag completely?  Or did it see a value of 0 for the mag, assume you had suddenly rotated to face the north, and thus respond by trying to move back to the original heading (anything other than north).  I would consider that a bug.  If the mag fails mid-flight, the code should immediately stop looking at the mag heading, and just do the yaw dead-reckoning as best it can.

  • You know you were supposed to solder those locating pins because they provide power and ground not supplied by that connector right?

    Wow, I just realized you posted in both threads. All I can say is solder the pins before you crash. I mean you posted April 21st and explained why you didn't solder after we told someone else they must be soldered, then you noticed your GPS didn't work, and then you now had this issue.  Solder the pins before you get hurt or crash the Heli into someone! Does "Captain Obvious" need to visit on this one?
