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.

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.

There is another phenomenon. After a period of time after I connect to the device, the device will automatically disconnect and the feedback code is 19 (BLE_HCI_REMOTE_USER_TERMINATED_CONNECTION). However, this problem did not occur when I used SD_API_V5 before. My scanning parameters and connection The parameters are the same as before.
