BLE connect device but don't have connect handle

[MapleBay]

When I am in BLE_GAP_CONNECTED event, the connection handle is empty?

This is log:

[17:54:15.251]input←◆<info> app: Received BLE event: 16
<info> app: Connected.
<info> app: Connection handle: 0x0
<info> app: Connected to device with handle: 0x0000

<info> app: Received BLE event: 35

[17:54:55.269]input←◆<info> app: Received BLE event: 17
<info> app: Disconnected, reason 34.

In connect event, I can't get the connect handle. Why?

Thanks response.

Hello,

What do you mean by "In connect event, I can't get the connect handle."?

[17:54:15.251]input←◆<info> app: Received BLE event: 16
<info> app: Connected.
<info> app: Connection handle: 0x0
<info> app: Connected to device with handle: 0x0000

According to this log, it seems like you got the connection handle. It is 0x0000, isn't it?

Best regards,

Hello,

Yes, but I think it shouldn't be 0x0000, because I use this handle to disconnect it will return error 0x3002.

Hello,

0x3002 is BLE_ERROR_INVALID_CONN_HANDLE, so I understand that you would think that. 

Where do you try to disconnect? Could it be that you are trying to do that in the disconnected event? If so, it would already have been disconnected. 

If it is not in the BLE_GAP_EVT_DISCONNECTED event, from where are you trying to call sd_ble_gap_disconnect?

Hello,

I open a serial port to control my app, than I call sd_ble_gap_disconnect() after BLE_GAP_EVT_CONNECT event. So I sure I am in the connection.

Can you please .zip and upload the application that you are using so that I can have a look? Will I be able to reproduce this using an nRF52840DK?

I use the pca10059 with nRF52840 dongle.

The command is :">SD:Connect=3_1122334455f6", "3" is type, "1122334455f6" is address. And ">SD:Disconnect".

Ok, I don't have time to look into it now at the end of the day, but try printing, or debugging the value of m_connection_handle right before you call sd_ble_gap_disconnect(), and see if it is still 0x0000.
