I am using a KEYESTUDIO GPS Module connected to a RPi 3B+. The Keyestudio outputs NMEA 0183 data at 9600 and I have this connected to the Rx pin on RPi (pin 10, GPIO15).
I did have it working and displaying in both OpenCPN and Signal K but following various updates I now can’t get it to display any GPS data.
I have the latest versions of all apps installed.
Running Check System in Settings gives the following warning:
GPIO service running
I have used sudo raspi-config to ensure:
The serial login shell is disabled │
The serial interface is enabled
If I use
I get garbled NMEA data:
GPGGA,1409,N,00127.591140,M,48.0A,3,22,1,14,23,01.04*00
$GPGSV,,29,07,02,264,09,50,072,20*7E
0,09,297,33,32,1GLL,5503.18009,N41923.00$GPRMC,141924.0000127.59117,W,0.68
$GPV,0.085,K,A*2C
However, if I set raspi-config to:
The serial login shell is enabled │
The serial interface is enabled
Running cat /dev/ttyAMA0 gives me a Permission Denied error. Running sudo cat /dev/ttyAMA0 gives me well formed NMEA data:
$GPGGA,143046.00,5503.17983,N,00127.58878,W,1,10,1.07,38.1,M,48.0,M,,*72
$GPGSA,A,3,22,28,21,27,01,30,32,14,08,10,,,1.84,1.07,1.50*0E
… and a Permission Denied message against the gps connection in Signal K.
I have been going around in circles with this so any advice greatly appreciated.
