Sodaq sara sff r410m i2c gps_adr

Hi!

I just changed boards from the AFF R410M to the SFF version. Currently I am trying to get my old software to work on the board. The first thing i’m trying to do is writing configuration to the Ublox receiver in order to enable Galileo and disabling some NMEA sentences. I’ve understood that the two boards use different Ublox receivers (SAM-M8Q for the AFF and EVA-8M for the SFF) and was wondering if there is any difference in how you would communicate with it. For the AFF im using the Wire library to use I2C and writing my byte arrays to address 0x42 like the following:

byte disableGGA[] = {0xB5, 0x62, 0x06, 0x01, 0x08, 0x00, 0xF0, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x01, 0x00, 0x24};
Wire.beginTransmission(0x42);
Wire.write(&disableGGA[0], sizeof(disableGGA));
Wire.endTransmission();

This works well on the AFF but when I try it with the SFF, the program gets stuck after Wire.endTransmission(). Is the SFF using some other I2C address or am I missing something else?

Thanks in advance!
