Setting slave connection interval (same as GAP PPCP?)

[sam]

Hi,

I'm wondering if the slave connection interval range is the same as the GAP peripheral preferred connection parameters i.e. does it make sense to do the following (GAP connection parameters have been set before):

ble_gap_conn_params_t    gapConnParams;
sd_ble_gap_ppcp_get(&gapConnParams);

p_advertising->slave_conn_int.min_conn_interval = gapConnParams.min_conn_interval;
p_advertising->slave_conn_int.max_conn_interval = gapConnParams.max_conn_interval;

Thanks

Hi,

The sd_ble_gap_ppcp_get(...) is used to get the peripheral Preferred Connection Parameters.

When you set it like this:

gap_conn_params.min_conn_interval = MIN_CONN_INTERVAL;
gap_conn_params.max_conn_interval = MAX_CONN_INTERVAL;
gap_conn_params.slave_latency     = SLAVE_LATENCY;
gap_conn_params.conn_sup_timeout  = CONN_SUP_TIMEOUT;

err_code = sd_ble_gap_ppcp_set(&gap_conn_params);
APP_ERROR_CHECK(err_code);

You can later use the function sd_ble_gap_ppcp_get(...) to get the parameters(gap_conn_params) that the softdevice is currently set to use.

The connection interval range is normally not part of the advertising or scan response packet.

What example in the SDK are you looking at?
