CH582M从机连接参数更新失败和服务时间较长要如何解决？

这个发现速度慢的根本原因,是整个发现过程中的连接间隔比较长,

上面的错误是连接间隔更改失败, 根本原因是 代码在初始化时候给连接间隔限制了一个较小的范围,,

实际上你可以修改为更大的范围,如(代码来自 CH583EVT_v1.1EVTEXAMBLEBLE_UART ):

void Peripheral_Init( )
{
Peripheral_TaskID = TMOS_ProcessEventRegister( Peripheral_ProcessEvent );

// Setup the GAP Peripheral Role Profile
{
uint8 initial_advertising_enable = TRUE;
uint16 desired_min_interval = 6;
uint16 desired_max_interval = 1000;

// Set the GAP Role Parameters
GAPRole_SetParameter( GAPROLE_ADVERT_ENABLED, sizeof( uint8 ), &initial_advertising_enable );
GAPRole_SetParameter( GAPROLE_SCAN_RSP_DATA, sizeof ( scanRspData ), scanRspData );
GAPRole_SetParameter( GAPROLE_ADVERT_DATA, sizeof( advertData ), advertData );
GAPRole_SetParameter( GAPROLE_MIN_CONN_INTERVAL, sizeof( uint16 ), &desired_min_interval );
GAPRole_SetParameter( GAPROLE_MAX_CONN_INTERVAL, sizeof( uint16 ), &desired_max_interval );
}
后面从机可以根据实际的应用需求,再去请求主机更新需要的连接参数

if ( events & SBP_PARAM_UPDATE_EVT )
{
// Send connect param update request
GAPRole_PeripheralConnParamUpdateReq( peripheralConnList.connHandle,
DEFAULT_DESIRED_MIN_CONN_INTERVAL,
DEFAULT_DESIRED_MAX_CONN_INTERVAL,
DEFAULT_DESIRED_SLAVE_LATENCY,
DEFAULT_DESIRED_CONN_TIMEOUT,
Peripheral_TaskID);


// GAPRole_PeripheralConnParamUpdateReq( peripheralConnList.connHandle,
// 10,
// 20,
// 0,
// 400,
// Peripheral_TaskID);
