hi Chris,
i had tried that use ublox center in windows and it get lock within 1
minute,(first time), but when it goes on my lisa/m2.0, it is another
story. the GPS is very hard to get locked, up to 10~20 minutes to get
locked on my balcony. in the field it takes more than 2 minutes. i
dont know what causes this.
