Regarding sparkfun’s guide, I think that may be related to the use the LED.
We did test this in the past.. and I just tested now, it does work. The Pi can see the pin go high
On a Pi 4 i connected the TP pin from the SARA-R5 to GPIO21 on the PI.
I created a python script to see when this goes high;
import RPi.GPIO as GPIO GPIO.setmode(GPIO.BCM) GPIO.setup(21, GPIO.IN) while True: if GPIO.input(21): print (" high!")
I then configured the below commands on the SARA-R5
AT+UTIMEIND=1 AT+UTIME=1,1 AT+UGPS=1,4,67
The python script was able to see the pin go high every second.
