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?

Any updates on this one?

Hi,

Can you please look at my previous post and answer the few questions there? It will hopefully bring us closer to understanding what is going on.

3mA average while connected,

Here are the Connection params:

Hi,

OK, so we see that the connection interval chosen by the central is 0x18 * 1.25 ms = 30 ms, which matches the current spikes. You only call sd_ble_gap_ppcp_set() in the code snippet. Most likely the central ignores / never reads this, so you should also request a connection parameter update if you find the connection parameters unacceptable. You can do this with sd_ble_gap_conn_param_update() directly, or using the connection parameters module which is used in for example the Heart Rate Application example.

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?
