Can't get GPS module working

[SYN-Vaibhav-Ranbhare]

I have a GPS module installed in a GrovePI, using the RPISER port. (Raspberry Pi 3).

using ser = serial.Serial('dev/ttyAMA0',9600, timeout=0 ) # open serial port. ... GPS.inp = ser.readline() print(GPS.inp)
Result
b''
b''

Using following config setting.
dtoverlay=pi3-diable-bt
enable_uart=1
core_freq=250

I am having this problem as well in July. A solution would be nice.

On a Pi3, or Pi3B+ some configuration is needed.

Step 1:
in /boot/config.txt, add at the end of the file:
dtoverlay=pi3-miniuart-bt
dtoverlay=pi3-disable-bt
enable_uart=1

Step 2:
in /boot/cmdline.txt remove :
console=ttyAMA0,115200 console=tty1
and add:
plymouth.ignore-serial-consoles

Step 3:
reboot.
