DFU over BLE using SMP failing when device is in Error state

Question

We are using the CAF Power Manager module and CAF Simple Management Protocol module. The DFU over SMP works like a charm using the nrf connect app when the device is in a normal state (all module report MODULE_STATE_READY). However, if a module report a MODULE_STATE_ERROR and the CAF PM module switch into the error state, the DFU fails, even if the CONFIG_CAF_POWER_MANAGER_ERROR_TIMEOUT is not yet reached. It seems that the SMP module fails to allocate the necessary buffers used for communication: net_buf: net_buf_alloc():1259: Failed to get free buffer mcumgr_smp: smp_bt_chr_write: failed net_buf alloc for SMP packet Is there a way to use DFU over SMP even from an application Error state ?
