Well, I think I found the issue. On line #3365 in
plugins/huawei/mm-broadband-modem-huawei.c, I found this:
static char *gps_startup[] = {
"^WPDOM=0",
"^WPDST=1",
"^WPDFR=65535,30",
"^WPDGP",
NULL
};
http://cgit.freedesktop.org/ModemManager/ModemManager/tree/plugins/huawei/mm-broadband-modem-huawei.c?id=1.4.0
So, I guess I need to change this, unless there is a way to do this at
runtime?
