ble_app_uart_c example sd_ble_gap_disconnec function failure

[azjo]

Hi, I am running ble_app_uart_c example with a PCA10056 DK board. I modified the example to accept command from uart. Everything look OK. But when I tried to command the host to disconnect from peripheral by the following code:

err_code = sd_ble_gap_disconnect(conn_handle,
BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION);
iAPP_ERROR_CHECK(err_code);

I got the following error:

<error> nrf_ble_gq: SD GATT procedure (1) failed on connection handle 0 with error: 0x00000008.
<error> app: Fatal error

Then the device got reset.

Any idea how to fix the issue? Thanks.

Hi.

sd_ble_gap_disconnect() returning with err_code 08:

NRF_ERROR_INVALID_STATE - Disconnection in progress or link has not beeen established.

Which implies that you aren't actually in an active connection when the disconnection call is made. Could you verify that you are in a connection at the time you make a call to disconnect?

Br,
Joakim

Hi Jookim,

I have verified that a connection has been established and I saw the central device and peripheral device could send and receive data bidirectionally. If no disconnect command was issued. The connection was running OK.

Thanks for your help.
