SMP server with can not connect

[binhla]

Dear all,

I am testing the SMP server example with NRF52832DK.

I have changed CONFIG_MCUMGR_SMP_BT=y

The device is advertising with Zephyr name. But mobile app cannot connet to it.

Here is log on the soc.

Hi,

The disconnect reason 13 indicate that the phone disconnected for some reason (Remote User Terminated Connection). Which phone are you using, and which mobile app? Can you test with nRF Connect for Mobile, and upload the log from that here it it does not work?

Dears,

Thank you for your prompt response.

The issue is solved. My mobile phone must forget the bluetooth connection with the device.

Best regards.
