CC2642R: RTOS: 我無法通過icall_fetchservicemsg()回傳值不會變更

chipset: CC2640R2F

sdk: simplelink_cc13x2_26x2_sdk_2_40_00_81

IDE: IAR8.22.2

您好

我寫了2個藍芽notify function分別為Ble_Send_Task跟Ble_Send_Task_251用來傳送DATA，寫法基本一樣，差異只有藍芽傳送封包長度

現在遇到使用Ble_Send_Task 傳送數據後，disconnect再次連接devic是可以成功的，功能也正常

使用Ble_Send_Task_251後卻不能再次連線，後來發現是在SimplePeripheral_taskFxn 的for loop中ICall_fetchServiceMsg這個fxn回傳值不為ICALL_ERRNO_SUCCESS

導致後面GAP paring也沒辦法

使用Ble_Send_Task_251後ICall_fetchServiceMsg只會回傳ICALL_ERRNO_NOMSG

Please Suggest what could be going wrong.
