High power when connected and Sleeping

[mraposo1]

When Going into Sleep, I see peaks of 12mA every 30ms (see image)
I'm assuming I can adjust that changing the connection interval settings.
I have my Connection intervals set as:

#define CONN_INTERVAL_DEFAULT (uint16_t)(MSEC_TO_UNITS(500, UNIT_1_25_MS))
#define CONN_INTERVAL_MIN (uint16_t)(MSEC_TO_UNITS(500, UNIT_1_25_MS))
#define CONN_INTERVAL_MAX (uint16_t)(MSEC_TO_UNITS(600, UNIT_1_25_MS)) 

And I think I looked at all issues in the Devzone about it without any luck.

Could you help me please?

Hi,

It is difficult to recognize the power profile as the time resolution is not good, but it looks like the device is advertising and not in a connected state. Can you verify that? If so, you have to adjust the advertising interval instead. You can increase the advertising interval by increasing the value of APP_ADV_INTERVAL in most BLE peripheral examples.

Here is what I tried inside on_ble_gap_evt_connected:

ble_gap_conn_params_t ConnParams;

ConnParams.min_conn_interval = 0xF0;
ConnParams.max_conn_interval = 0xF0;
ConnParams.conn_sup_timeout = 0x200;

if (p_gap_evt->conn_handle != 0)
{
err_code = sd_ble_gap_conn_param_update(p_gap_evt->conn_handle, &ConnParams);
APP_ERROR_CHECK(err_code);
}

But p_gap_evt->conn_handle is always 0. 
How is that even possible?

You are right, the conn_handle should not be 0 when you have a connected event. Can you upload the rest of your code to provide more context? Which SDK version are you using?
