SMP server: Authentication is insufficient

[binhla]

Dear all.

I am testing SMP server example with the nRF52832DK kit.

I did what described here FOTA over BLE.

In step3, the app nRF Connect for Mobile reported failure: Authentication is insufficient.

So there must be something wrong with my app_update.bin file.

I also tried with the app nRF Toolbox get the error too.

Please help.

Best regards.

Hello,

Please make sure CONFIG_MCUMGR_SMP_BT_AUTHEN is disabled in your project .conf files. Otherwise, you have to modify the example to support authentication.

Best regards,

Dears,

Thank you for your prompt response.

The issue is solved after I made these config

# MCU mgr
CONFIG_MCUMGR_SMP_BT=y
CONFIG_MCUMGR_SMP_BT_AUTHEN=n
CONFIG_MCUMGR_SMP_BT_CONN_PARAM_CONTROL=y

# Allow for large Bluetooth data packets.
CONFIG_BT_L2CAP_TX_MTU=498
CONFIG_BT_BUF_ACL_RX_SIZE=502
CONFIG_BT_BUF_ACL_TX_SIZE=502
CONFIG_BT_CTLR_DATA_LENGTH_MAX=251

Best regards.
