i'm looking for some help , i already try that way to communicate using i2c but still no respond from gps ublox neo 6m
i attached a picture of result on serial monitor for that code.
u-blox doesn't list a CN-06 device on their website (http://www.u-blox.ch). So provide a link for all the hardware you actually have!
Your adapter board already includes an ATmega328p processor (if I found the correct one, that's why you always must provide links to all hardware and libraries you use). That processor may need some firmware upgrade (Recipe to get Crius GPS + I2C Nav board to work - RC Groups).
i got that link from rctimer official page, the problem was my Crius I2C-GPS NAV Module Navigation Board can't send data .
i already solved this problem used i2c communication with 2 arduino uno.
