+### GPRS fiddling
|
|
|
|
|
+
|
|
|
|
|
+I'm still trying to get GPRS to work consistently.
|
|
|
|
|
+
|
|
|
|
|
+Once the system is setup, it seems like it's pretty consistent, but getting `/dev/ttyGPRS` to be
|
|
|
|
|
+consistently tied to the appropriate device is proving difficult...sometimes `/dev/ttyAMA0` works,
|
|
|
|
|
+sometimes it's `/dev/serial0`, sometimes it's `/dev/ttyUSB0`, othertimes it looks like `/dev/ttyUSB2` works.
|
|
|
|
|
+
|
|
|
|
|
+I notice messages of this sort happening most recently which could or could not be related to the the GPRS not working (`/var/log/syslog`):
|
|
|
|
|

|
|
|
|
|
+```
|
|
|
|
|

|
|

|

|
|
|
|
|
+I followed [this](https://raspberrypi.stackexchange.com/questions/39165/how-can-i-stop-the-auto-login-console-and-getty-in-raspbian-8-jessie):
|
|
|
|
|
+
|
|
|
|
|
+```
|
|
|
|
|
+systemctl stop serial-getty@ttyAMA0.service
|
