连接间隔数据传输慢速

亲爱的对话框

我使用下面的代码在DA14583上改变了连接间隔

struct gapc_param_update_cmd * req = ke_msg_alloc（gapc_param_update_cmd，task_gapc，task_app，gapc_param_update_cmd）;

//填写参数结构
req->操作= gapc_update_params;
if（do_fast）{
req-> params.intv_min = ms_to_doubleslots（10）;// n * 1.25ms
req-> params.intv_max = ms_to_doubleslots（20）;// n * 1.25ms
req-> params.time_out = ms_to_timerUnits（1250）;// n * 10ms

}
别的
{
req-> params.intv_min = ms_to_doubleslots（150）;// n * 1.25ms
req-> params.intv_max = ms_to_doubleslots（200）;// n * 1.25ms
req-> params.time_out = ms_to_timerUnits（6000）;// n * 10ms
}
req-> params.latency = 0;// conn事件跳过
KE_MSG_SEND（REQ）;

Now when I set the parameters to the slow values i.e 150,200,6000 and then through an iOS app write to around 4 bytes to a BLE characteristic, on the 14583, the data is received after around 4 seconds by the 14583. Is there a special mechanism to maintain the data transfer speed when we increase the connection interval or is this the expected behaviour.
