GATT CONN TERMINATE LOCAL HOST occurs when bonding with Android

[sdi_kei]

Hello.

I am developing using nrf52832 (S132 v7.0.1, SDK v17.0.0).

Since I want to bond with Android, I have created a central code that summarizes the functions that I think are necessary by referring to various sample sources.
On Android, a pairing request is displayed, but when I press connect, it becomes GATT CONN TERMINATE LOCAL HOST and I cannot bond.
Does anyone know how to deal with it?

I can't use nRF Sniffer because I don't have two boards.

Best regards.

Hi

Did you add the Nordic UART service as part of your advertiser on Android, as the application scans peripheral devices and connects to a device that advertises with the NUS UUID in its advertisement report. After connecting, the application enables notifications on the device that delivers the Nordic UART Service.

Best regards,

Simon

Hello.

Does that mean I have to register NUS GATT?
It is possible to connect with Android, and I think it is a matter of bonding at that time. So I think GATT has nothing to do with it.

If I need GATT, I have to add it to nRF Connect, but I don't know the data structure. Is there any material that describes the configuration?

Best regards.
