CC2640R2F: CC2640R2F 修改MTU 从机判断修改成功标志

请问：我的手机APP 是主机。 板子是从机。 主机主动修改MTU为251字节，从机怎么判断修改MTU成功？ 

Kevin Qiu1：

修改成功后会在串口打印MTU size信息

static uint8_t SimplePeripheral_processGATTMsg(gattMsgEvent_t *pMsg)
{if (pMsg->method == ATT_FLOW_CTRL_VIOLATED_EVENT){// ATT request-response or indication-confirmation flow control is// violated. All subsequent ATT requests or indications will be dropped.// The app is informed in case it wants to drop the connection.// Display the opcode of the message that caused the violation.Display_printf(dispHandle, SP_ROW_STATUS_1, 0, "FC Violated: %d", pMsg->msg.flowCtrlEvt.opcode);}else if (pMsg->method == ATT_MTU_UPDATED_EVENT){// MTU size updatedDisplay_printf(dispHandle, SP_ROW_STATUS_1, 0, "MTU Size: %d", pMsg->msg.mtuEvt.MTU);}// Free message payload. Needed only for ATT Protocol messagesGATT_bm_free(&pMsg->msg, pMsg->method);// It's safe to free the incoming messagereturn (TRUE);
}

你好，请问这个函数是在主机端还是从机端？  我现在是从机端判断。
