无法在调制解调器上接收Flash（Class 0）SMS

我正在使用SIM800调制解调器（Dinstar）进行AT命令，在STK 发送简短消息之后，我无法获得STK命令的响应。

使用手机时，该过程如下：

启动STK应用程序
通过STK菜单导航到我想要
输入数据（电话号码，金额）的
选项确认选择然后，手机显示（加载...），然后5秒钟后，STK应用显示一条消息，告知用户操作是否成功。

我的问题是在使用调制解调器时，我看不到消息通知用户操作是否成功。以下是每个结果与每个结果一起使用的AT命令：

此后，即使在很长一段时间后也没有从调制解调器发送。 +STKPCI在我看来发送简短消息发送了简短的消息。我也不知道什么 0101038154F5000410E18B8FBAC72115E05B54866E5C667593 是指在文档中，这应该是SMS TPDU，但我无法解码/parse/parse IT。我需要能够发送STK SMS，而无需一遍又一遍地浏览菜单。

仅供参考，我正在通过TCP插座而不是串行连接连接到调制解调器，我正在使用的调制解调器是Dinstar UC2000-VE。

编辑：使用AT命令 AT+STKSMS = 0 ，我能够在手机上接收总结，但是网关侧没有显示任何内容。当我使用手机时，我能够在音调说明操作是否成功后看到确认消息。

编辑2：我正在添加另一个简单的示例，该示例不需要用户输入，而是机密代码：获取用户平衡，同样的问题执行我可以看到加载...消息...消息，但是在使用手机时什么也没有返回加载后，我可以看到我的平衡。 Here are the AT commands executed:

原文

I am experiencing with AT commands using a sim800 modem (Dinstar), I am unable to get the response of the STK command after STK send short message.

When using my phone, the process goes as follows:

Start the STK app
Navigate through the STK menu to the option I want
Input data (phone number, amount)
Confirm the choice
The phone then shows (Loading...), then after 5 seconds, the STK app shows a message informing the user if the operation was successful or not.

My problem is while using the modem, I am not able to see the message informing the user if the operation was successful or not.
Here are the AT commands used with the result of each one:

at+stktrs=00,01

After this, nothing is sent from the modem even after a long time.
the +STKPCI SEND SHORT MESSAGE in my opinion sends the Short message. I also do not know what 0101038154F5000410E18B8FBAC72115E05B54866E5C667593 means, in the docs, this should be the SMS tpdu but I am not able to decode/parse it. I need to be able to send the STK SMS without browsing through the menu over and over again.

FYI, I am connecting to the modem via a TCP socket and not a serial connection, the modem I'm using is a Dinstar UC2000-VE.

EDIT: After using the at command AT+STKSMS=0, I am able to receive the topup on my phone, but nothing is shown on the gateway side. When I am using the phone, I am able to see a confirmation message after the tone stating if the operation was successful or not.

EDIT 2: I am adding another simple example which requires no user input but the confidential code: getting user balance, same problem the request is executed I am able to see the loading... message but nothing is returned after, while using the phone I am able to see my balance after the loading... message. Here are the AT commands executed:

彻底研究了这一点。我找到了一种按预期工作的解决方案，但有些怪异。

在发送STK短消息并接收播放音调STKPCI

at+stksms=0
OK
+STKPCI: 2
+STKPCI: 0,PLAY TONE

发送AT+STKTRS = 10后，似乎获得了显示文本STKPCI，根据手册，STKTRS '10'=主动sim会终止。

现在看起来像这样：

at+stksms=0
OK
+STKPCI: 2
+STKPCI: 0,PLAY TONE
at+stktrs=10
OK
+STKPCI: 0,DISPLAY TEXT,129,046F7005726174696F6E200563686F7505653A20566575696C6C657A207205657373617965722E

显示文本是操作的结果，但是我不太明白为什么发送 +stkpci：2之后我需要关闭会话，这是根据手册含义< em> 2没有其他命令（会话结束）

After thoroughly looking into this. I found a solution that is working as expected but a little bit weird.

After sending the STK short message and receiving the play tone STKPCI

at+stksms=0
OK
+STKPCI: 2
+STKPCI: 0,PLAY TONE

Sending an AT+STKTRS=10 seems to get the DISPLAY TEXT STKPCI, according to the manual, STKTRS '10' = Proactive SIM session terminated by the user.

Now it looks something like this:

at+stksms=0
OK
+STKPCI: 2
+STKPCI: 0,PLAY TONE
at+stktrs=10
OK
+STKPCI: 0,DISPLAY TEXT,129,046F7005726174696F6E200563686F7505653A20566575696C6C657A207205657373617965722E

The display text is the result of the operation, but I don't quite understand why do I need to close the session after the +STKPCI:2 is sent, which according to the manual means 2 No other command (end of session)
