Adafruit Ultimate GPS cannot get fixed data

Post by zhoucx »

My Adafruit Ultimate GPS is connected with Beaglebone Black. GPS TX -> BBB P9.11 GPS RX -> BBB P9.13 GPS PPS -> BBB P8.4

After I enabled UART4, I use “cat /dev/ttyO4” to check the data
But these data is not fixed. I tried both way, connected Beaglebone Black with computer use USB cable or support Beaglebone Black with 5V directly. Also I tried outside without high building. The LED always keeps blinking every second.
What else should I do to let the GPS get fixed data?
