I recently bought a mosaicHAT. I’m able to connect via Ethernet-over-USB and i can see the Septentrio Interface.
I also connected the HAT via GPIO pins but I cannot receive any NMEA from it.
Neither on https://github.com/septentrio-gnss/mosaicHAT nor on your Q&A I could find a reasonable solution for receiving NMEA from the HAT.
When I try to connect to /dev/ttyAMA0 nothing arrives. So what should i activate on the mosaic to transmit GGAs? Within the WebUI i activated NMEA-GGA-1 sec on COM1,2,3,4 but my connections does not showing up.
Do i have to use another Interface than COMx?
kind regards, Jiargei
I think I found a solution: on the Raspberry Pi 3 there is also a device /dev/serial0 which is the correct port! One strange thing, I cannot make it work with baud rate 115200, I had to decrease it to baud rate 57600 and lower to make it work!
So at least for my Pis:
- Raspberry PI 2: /dev/ttyAMA0:115200
- Raspberry PI 3: /dev/serial0:57600
- Raspberry PI 4: /dev/serial0:57600
