U1177A红外蓝牙连接失败和U1232A万用表

我最近买了一台带U1177A红外蓝牙模块的U1232A。
我能够将U1177A模块连接到我的Android设备和PC，但DMM仍然在我的Android设备上显示为“Meter not connected”，并且PC日志记录软件无法检测到DMM。
所以不用说它没有显示Android Meter或Logging App上的读数。
然而，当我处于设置模式时，我能够确认DMM能够与BT模块“对话”。
当U1177A处于设置模式时，在PC上，我可以看到并更改默认设置：+连接U1177A> ati？+ + F / W VERSION：v4.378 + +连接U1177A> ati1 + ATG = 900，ENABLE ENTER
睡眠模式;
启用UART唤醒+ + ATH = 1，DISCOVERABLE + + ATK = 0，一个停止位+ + ATL = 1，波特率为9600+ + ATM = 0，无PARITY_BIT + + ATN = U1177A，本地名称+ + ATP = 1234，PIN码+
+ ATQ = 1，从不发送结果代码+当我在DMM上将刻度盘更改为不同的测量值时，它也会显示：+连接U1177A> * 2 + + * 3 + + * 2 + + * 1 + + * 0 + + *

U1177A> atib？+ + 0012-6f-2c3089> atb？+所以我知道DMM正在向BT模块发送IR信息。
我还缺少什么？



     以下为原文

  I recently bought a U1232A with the U1177A IR-Bluetooth module. I am able to get the U1177A module to connect to my android device and PC, but the DMM still shows as "Meter not connected" on my Android device and the PC logging software fails to detect the DMM. So needless to say it is not showing the readings on the Android Meter or Logging App. I am however able to confirm that the DMM is able to "talk" to the BT module when I am in setup mode.

While the U1177A is in setup mode, on the PC, I can see and change the default settings:

+Connect U1177A>ati?+
+F/W VERSION: v4.378+

+Connect U1177A>ati1
+ATG=900, ENABLE ENTER SLEEP MODE; ENABLE UART TO WAKE UP+
+ATH=1, DISCOVERABLE+
+ATK=0, ONE STOP BIT+
+ATL=1, BAUD RATE is 9600+
+ATM=0, NONE PARITY_BIT+
+ATN=U1177A, LOCAL NAME+
+ATP=1234, PIN CODE+  
+ATQ=1, NEVER SEND RESULT CODE+  

It also shows when I change the dial to a different measurement on the DMM:

+Connect U1177A>*2+
+*3+
+*2+
+*1+
+*0+
+*1+

When I keep hitting the TrigHold button, it would show the following:

+Connect U1177A>*1+
+"010013612000200"+
+"010008412000200"+
+"010005712000200"+
+"010008012000200"+
+"010003712000200"+

+Connect U1177A>atib?+
+0012-6f-2c3089>atb?+


So I do know the DMM is sending IR info to the BT module.

What else am I missing?
