AQ6 w/ DIMU : mag-cal. & follow me ?

[Crizz]

I dont get connected at 115 kBaud, tried everything, only at 57.6 kbaud i got a connect - and loose it after 2 seconds again.

That´s because the modules come preconfigured at 57k for APM.
But there´s a handy tool for an easy setup: http://ardupilot.com/downloads/?did=89

problem with changing gps-locks between 2d and 3d solved : antenna is bad !

Got a replacement from Dkue40 for testings and worked perfect, guess my antenna has too much current draw when it get warm of bad solderwork at the intgerated amplifier that causes the problem. Even with only dipole , 3d lock stayed continously ( though it took nearly 3 times longer to get 3d fix - with well working active gps-antenna, 3d lock was announced within 3-4 seconds after 2d lock)

Considering all of this i can only advice to keep a "u.FL.-cable " and making a dipole like described in the manual for AQ M4 - it´s a very simple and affordable tool to check if the antenna is bad instead of keeping a replacement on stock, though it doesnt give you a statement of the antennas voltage supply, this has to be measured manually, but guess in almost every case it will be a bad antenna that causes the problem and not a faulty uBlox-module.

Glad you found the problem, Chris!
Those u.fl connectors and wire don´t take much tear&wear. I once bent the thin pin in the plug with similar results...
