Currently only IPv4 is supported. APN is not stored to modem's non-volatile memory. oFono will manage this default APN via it's config storage. When receiving an empty default APN, the value is reset. --- drivers/ubloxmodem/lte.c | 154 ++++++++++++++++++++++++++++++++++++= ++++ drivers/ubloxmodem/ubloxmodem.c | 3 + drivers/ubloxmodem/ubloxmodem.h | 5 ++ 3 files changed, 162 insertions(+) create mode 100644 drivers/ubloxmodem/lte.c diff --git a/drivers/ubloxmodem/lte.c b/drivers/ubloxmodem/lte.c new file mode 100644 index 0000000..43c02d4 --- /dev/null +++ b/drivers/ubloxmodem/lte.c @@ -0,0 +1,154 @@ +/* + * + * oFono - Open Source Telephony + * + * Copyright (C) 2016 Endocode AG.
