FOTA over Bluetooth Low Energy

Hello, I have implemented the FOTA function according to the official documentation. Now, I would like to add a switch for enabling and disabling FOTA. Our product is used in automobiles. When the car engine is started, FOTA is prohibited. It is only allowed when the car engine is turned off. Should I call that function to achieve this functionality?

Hello,

BLE DFU/FOTA uses the MCUmgr SMP Bluetooth transport. A common way to enable or disable it at runtime is by dynamically registering or unregistering the SMP Bluetooth GATT service.

You can enable it using smp_bt_register() and disable it with smp_bt_unregister(). To support this, make sure CONFIG_MCUMGR_TRANSPORT_BT_DYNAMIC_SVC_REGISTRATION=y is enabled in your configuration. See the smp_bt.h

Kind Regards,
