change connection interval

[kk]

Hi,every one!

As far as i konw, the original connection interval that ios sets is about 50ms, that is a little too fast for me, so i want to change the connection interval after connection.

and my code is(i do it after connection):

memset(&gap_conn_params2, 0, sizeof(mynewparams));	
mynewparams.min_conn_interval = MIN_CONN_INTERVAL;
mynewparams.max_conn_interval = MAX_CONN_INTERVAL;
mynewparams.slave_latency     = SLAVE_LATENCY;
mynewparams.conn_sup_timeout  = CONN_SUP_TIMEOUT;
ble_conn_params_change_conn_params(&mynewparams);

and then i found out the following problems: 1.if MIN_CONN_INTERVAL > 50ms, the connection will disconnect automatically 2.if MIN_CONN_INTERVAL < 50ms, seems the connection interval does not change becaues the current comsumption does not change

so how to explain this?

to make it right, are there something also should be done on smart phone or just modify the device is enough?

thank you for your wachting!

Have you followed the guidelines given on page 22 in this apple document? developer.apple.com/.../bluetoothdesignguidelines.pdf That should explain how you should select your connection parameters for an IOS device
