Hi There,
I have a pi4 that I am trying to get a ublox 7m GPS module working on via the UART GPIO15 pins.
I am stumped regarding the primary and secondary UART serial connections. Apparently on the pi4 they are different (with a miniuart) to the earlier ones
There are a few overlay options one can specify in the config.txt file I have tried a few already, resulting in ttyAMA0, ttyAMA1, ttyS0, but I still cannot get any of this data into signal k after aliasing the device and setting a connection in the serial dialog.
in my config.txt I have the following
dtoverlay=disable-bt
dtparam=spi=on
enable_uart=1
core_freq=250
dtoverlay=uart5,ctsrts
these values come from the https://www.raspberrypi.org/documentatio...ring-uarts
documentation. But I still cant work it out. Has anyone else had to deal with this?
The easy option is aparently to go and get a USB GPS dongle. But I had this ublox NEO 7m by duinotech. It has an onboard antenna but also an sma to run an external antenna. I have previously read the nmea gps messages in sudo cat /dev/(serial port). but not through to signal k.
The module and guts of connecting this device I found in this video https://youtu.be/N8fH0nc9v9Q but i did not run the python scripts as I wish to use it with OP.
An help would be appreciated.
Thanks
