-----------------------------------------------------------------simple_peripheral.c （初始化）

// After the connection is formed, the peripheral waits until the central
// device asks for its preferred connection parameters
#define DEFAULT_ENABLE_UPDATE_REQUEST GAPROLE_LINK_PARAM_UPDATE_WAIT_REMOTE_PARAMS

注意：需要特别注意DEFAULT_ENABLE_UPDATE_REQUEST。需要在其定义处修改成GAPROLE_LINK_PARAM_UPDATE_INITIATE_BOTH_PARAMS。这样双方都可以启动连接参数更新过程

uint8_t enableUpdateRequest = DEFAULT_ENABLE_UPDATE_REQUEST;
uint16_t desiredMinInterval = DEFAULT_DESIRED_MIN_CONN_INTERVAL;
uint16_t desiredMaxInterval = DEFAULT_DESIRED_MAX_CONN_INTERVAL;
uint16_t desiredSlaveLatency = DEFAULT_DESIRED_SLAVE_LATENCY;

uint16_t desiredConnTimeout = DEFAULT_DESIRED_CONN_TIMEOUT;

GAPRole_SetParameter(GAPROLE_PARAM_UPDATE_ENABLE, sizeof(uint8_t), &enableUpdateRequest);
GAPRole_SetParameter(GAPROLE_MIN_CONN_INTERVAL, sizeof(uint16_t), &desiredMinInterval);
GAPRole_SetParameter(GAPROLE_MAX_CONN_INTERVAL, sizeof(uint16_t), &desiredMaxInterval);
GAPRole_SetParameter(GAPROLE_SLAVE_LATENCY, sizeof(uint16_t), &desiredSlaveLatency);
GAPRole_SetParameter(GAPROLE_TIMEOUT_MULTIPLIER, sizeof(uint16_t), &desiredConnTimeout);
