CC2640 - 送GATT notification msg 2字元會error

您好

我想cc2640走BT透過SimpleProfile_SetParameter()送data到pc tool讀取，

但我發現當送2個字元時會失敗，而其它長度的值都成功，以下測試說明：

SimpleProfile_SetParameter(SIMPLEPROFILE_CHAR6, 1, "a");    // pc端能正常讀到"a"

SimpleProfile_SetParameter(SIMPLEPROFILE_CHAR6, 2, "ab");  // pc端讀不到

SimpleProfile_SetParameter(SIMPLEPROFILE_CHAR6, 3, "abc"); // pc端正常讀到"abc"

SimpleProfile_SetParameter(SIMPLEPROFILE_CHAR6, 4, "abcd"); // pc端正常讀到"abcd"

一路往下追：

    --> GATTServApp_ProcessCharCfg() //simpleProfileChar6 have data "ab"

    --> gattServApp_SendNotiInd() //pAttr->pValue have data "ab"

    --> GATT_Notification() //&noti, noti.pValue have data "ab"

    --> gattIndNoti() //msg->pIndNoti->handleValueNoti.pValue = "ab"

    --> sendWaitMatchCS()// 無法往下追了

是否有idea??
