When registering to an operator ofono uses the old RAT. In the case the modem is not connected to any network, this would use QMI_NAS_NETWORK_RAT_NONE which results in the error OP_DEVICE_UNSUPPORTED. Use QMI_NAS_NETWORK_RAT_NO_CHANGE instead to not define any preference. --- drivers/qmimodem/nas.h | 1 + drivers/qmimodem/network-registration.c | 2 +- 2 files changed, 2 insertions(+), 1 deletion(-) diff --git a/drivers/qmimodem/nas.h b/drivers/qmimodem/nas.h index 09807f83..d2feb464 100644 --- a/drivers/qmimodem/nas.h +++ b/drivers/qmimodem/nas.h @@ -97,6 +97,7 @@ struct qmi_nas_network_rat { } __attribute__((__packed__)) info[0]; } __attribute__((__packed__)); +#define QMI_NAS_NETWORK_RAT_NONE 0x00 #define QMI_NAS_NETWORK_RAT_GSM 0x04 #define QMI_NAS_NETWORK_RAT_UMTS 0x05 #define QMI_NAS_NETWORK_RAT_LTE 0x08 diff --git a/drivers/qmimodem/network-registration.c b/drivers/qmimodem/network-registration.c index 52ad69a6..04de5a5b 100644 --- a/drivers/qmimodem/network-registration.c +++ b/drivers/qmimodem/network-registration.c @@ -356,7 +356,7 @@ static void qmi_register_manual(struct ofono_netreg *netreg, info.mcc = atoi(mcc); info.mnc = atoi(mnc); - info.rat = data->current_rat; + info.rat = QMI_NAS_NETWORK_RAT_NO_CHANGE; qmi_param_append(param, QMI_NAS_PARAM_REGISTER_MANUAL_INFO, sizeof(info), &info); -- 2.13.3
