Error: [hci0]: can't init hci: can't up device: connection timed out is coming when checking the image list

[Dileep Kumar]

when trying to check the image list using smp server sample, the error cant init hci is coming. i disabled the mass storage device functionality foe the reason of error coming as failed to connect to peer after 10s.

Disable the Mass Storage feature on the Interface MCU, so that it does not interfere:

$ JLinkExe 
J-Link>MSDDisable
Probe configured successfully.
J-Link>SetHWFC Force
New configuration applies immediately.
J-Link>exit

Finally now iam not able to see the image list also.please suggest the solution for device firmware upgrade using BLE through NRF5340 SMP server

Hello,

Implementing the BLE DFU support for an application has been pointed out in two of your other tickets by my colleague. I recommend you follow that guide for adding OTA DFU support.

Hello,

How are you trying to transfer the image—are you trying using a mobile application or from the PC? In the guide pointed out, you specifically need to follow the DFU over Bluetooth section, not the serial DFU part. Refer to the FOTA section. Which SDK version are you using here?

Kind Regards,

Hello,

Yes, the Mcumgr tool on Linux allows BLE updates; for this, you can follow the zephyr Mcumgr guide. Do you have any logs from the nRF side?

Kind Regards,
