[参考译文] CC2340R5-Q1：总线传输速度对连接监视器的影响

您好、TI

我在连接监视器项目中看到了这段代码：(__LW_AT__sdk：simplelink_lowpower_f3_sdk_7_40_00_64：project、connection_monitor_LP_EM_CC2340R5_freertos_ticlang）

    // With a 100ms connection interval we will skip 3 channels into the future (in each connection event we can monitor 1 channel)
    // This is mainly done to ensure that even a very slow bus is able to send the connection information in time
    // In time: before the Central/Peripheral already go past the channel that we chose to listen on
    // If Central/Peripheral are already past this point, we will have to wait numChannels*connInterval until we catch the
    // connection once again
    chanSkip = (uint16_t)((BUS_LATENCY_IN_MS/connInterval) + 1);

    // Catch anchor point n+2 connection intervals in the future
    ubCMConnInfo.ArrayOfConnInfo[i].scanDuration = (uint16_t)(connInterval*(chanSkip + 1));

    // DeltaTime is the distance between the current time and time we received the data for the new connection.
    deltaTime = uble_timeDelta(currTime, reqTime);

    // Figure out how many connection events have passed since the last anchor point
    if (deltaTime > connInterval * BLE_TO_RAT)
    {
      chanSkip += (uint16_t) (deltaTime / (connInterval * BLE_TO_RAT) + 1);
    }

    ubCMConnInfo.ArrayOfConnInfo[i].currentChan = setNextDataChan(sessionId, chanSkip); //jump some [ms] channels into the future

此处说明了两点。

1.这主要是为了确保即使是非常慢的总线也能够及时发送连接信息。

2.如果中心/外围设备已经超过此点、我们将必须等待 numChannels*connInterval、直到我们再次接通连接。

我想、如果我通过 LIN 传输连接参数(至少40ms、拆分成多个数据包以10ms 的传输间隔)、很可能我已经错过了目标通道。  但等待时间超过 numChannels*connInterval 之后、我仍然没有 RSSI 事件。 我需要调整哪些参数？

此致
