Problem seen with a MC7304 modem and a roaming SIM card. Status in org.ofono.NetworkRegistration properties ends up in "registered" instead of roaming. Both AT command and qmicli indicates we are roaming. What's happening is the following: 1) first QMI_NAS_SS_INFO_IND indicating we are registered contains a QMI_NAS_RESULT_ROAMING_STATUS parameter. Parameter inside says we are roaming and qmimidem driver correctly reports status NETWORK_REGISTRATION_STATUS_ROAMING. 2) other QMI_NAS_SS_INFO_IND arrive, saying we are registered without QMI_NAS_RESULT_ROAMING_STATUS parameter. Driver reports NETWORK_REGISTRATION_STATUS_REGISTERED.

I have also seen (on MC7430, with a roaming SIM card): - first notification indicating status QMI_NAS_REGISTRATION_STATE_SEARCHING and roaming ON - following notifications indicating status QMI_NAS_REGISTRATION_STATE_REGISTERED and no roaming notification So we must handle roaming information even when not registered. |
