Problem with Ublox M8N SPI Interface, Please help

Posted by looke on July 27, 2016 at 7:47pm

Hi all

I have a problem when I try to use the SPI interface of M8N.

I read the ublox doc and it shows that "By default, all ports are configured for UBX and NMEA

protocol..."

However, U-center shows that the protocol on SPI is none.

So I tried to set the protocol but I got a notACK message from M8N. And the protocol on SPI remains none.

Then I connected the D_SEL pin of M8N to GND to enable the SPI port as the datasheet said. And attached M8N to Arduino SPI pins. Send some NEMA messages but all I got from M8N were unavailable bytes such as 0xED 0xFF...

Does anyone know how to config/use the SPI port of M8N?

Many thanks

    Hi Looke,

    I tried to connect m8n to raspberry with SPI, I have got the same problem you had. Do you solve it?

    Best regard,

    Robert
