m1	CAT-M1 bands to use. 0 to not change the bands.

Return values

0	Success.
-EINVAL	The band selection is illegal.

Note: This function needs to be called before mdm_sim7080_start_network(). If networking is already active, the change will not affect the current session. To apply changes, networking has to be restarted. A power cycle may be needed for the modem to forget the last working configuration.; Available NB-IoT and CAT-M1 differ. Refer to SIM7080_LTE_CHANNEL_MASK_NB1 and SIM7080_LTE_CHANNEL_MASK_M1.

◆ mdm_sim7080_set_rat()

int mdm_sim7080_set_rat ( enum sim7080_rat rat )

Set the radio technology.

Parameters

rat	The radio technology.

Return values

0	Success.
-EINVAL	The selected technology is not available.

Note: This function needs to be called before mdm_sim7080_start_network(). If networking is already active, the change will not affect the current session. To apply changes, networking has to be restarted. A power cycle may be needed for the modem to forget the last working configuration.

◆ mdm_sim7080_start_gnss()

int mdm_sim7080_start_gnss ( void )

Starts the modem in gnss operation mode.

Returns: 0 on success. Otherwise <0 is returned.

Note: The modem needs to be booted for this function to work. Concurrent use of network and gnss is not possible.

◆ mdm_sim7080_start_gnss_xtra()

int mdm_sim7080_start_gnss_xtra ( void )

Starts the modem in gnss operation mode with xtra functionality.

Returns: 0 on success. Otherwise <0 is returned.

Note: The modem needs to be booted for this function to work. Concurrent use of network and gnss is not possible.; If enabling xtra functionality fails a normal cold start will be performed.

Warning: On some modem firmware revisions (e.g. 1951B16SIM7080) power cycling the gnss functionality with an xtra file can cause a hangup of the modem. This can be triggered by calling mdm_sim7080_start_gnss_xtra(), then turning off gnss by calling mdm_sim7080_stop_gnss() and then re-enabling gnss by calling mdm_sim7080_start_gnss_xtra() again. In this case the modem will not respond to commands anymore and every call of a modem function will result in a timeout. In this case the whole modem needs to be power cycled by calling mdm_sim7080_power_off() and mdm_sim7080_power_on(). It is advised to power cycle the modem before using the gnss functionality to avoid hangups.

◆ mdm_sim7080_start_network()

int mdm_sim7080_start_network ( void )

Activates the network operation mode of the modem.

Returns: 0 on success. Otherwise <0 is returned.

Note: The modem needs to be booted for this function to work. Concurrent use of network and gnss is not possible.

◆ mdm_sim7080_stop_gnss()

int mdm_sim7080_stop_gnss ( void )

Stops the modem gnss operation mode.

Returns: 0 on success. Otherwise <0 is returned.

◆ mdm_sim7080_stop_network()

int mdm_sim7080_stop_network ( void )

Stops the networking operation mode of the modem.

Returns: 0 on success. Otherwise <0 is returned.
