有办法使用单个POST请求发送64 kByte的二进制数据块吗？

嗨，
我正在使用SPWF01SA1模块使用POST请求将数据从我的应用程序发送到中央服务器。
我需要使用单个POST请求传输64 kByte的二进制数据（application / octet-stream），因为我希望目标服务器接收单个传输命令，必须对其进行验证并确认回来以便正确接收。
我已经看到AT + S.HTTPPOST命令对最大长度有限制所以我不能使用它。
然后我将固件升级到版本3.5以尝试命令AT + S.HTTPREQ，构建我自己的POST头并能够在命令后发送数据。
通过这种方式，我设法发送了不到12 kByte的东西。在传输过程中，RTS信号每1024字节升一次，所以我插入一个暂停让缓冲区刷新。无论我在HTTPREQ命令和数据之间等待多长时间（我应该等待吗？）还是在RTS信号之间等待（所有这些信号都保持解除固定时间小于3.5毫秒并且我将暂停时间提高到1秒）：当数据量为11460字节或更多时，数据包将无法到达目的地，而11440字节的数据一切正常。
我目前的测试目的地是posttestserver.com，在那里我发现了几千字节（甚至一个略小于1 MByte）的存储消息，所以我认为这方面没有限制。
当传输失败时，SPWF01SA1没有说什么，我只是没有得到服务器的预期回复。
我还试图将我的单个POST请求拆分为一系列AT + S.HTTPREQ命令（一个用于POST头，一个用于32个字节的数据），但我无法使其工作。因此我认为这种分裂是不可能的。
我的问题：这个模块有没有办法使用单个POST请求发送64 kByte的二进制数据块？
传输大量数据的推荐方法是什么？
谢谢。

Hi,
I'm using a SPWF01SA1 module to send data from my application to a central server using POST requests.
I need to transfer 64 kByte of binary data (application/octet-stream) using a single POST request as I want the destination server to receive a single transfer command which must be validated and confirmed back for correct reception.
I've seen that the command AT+S.HTTPPOST has limitations on maximum length so I cannot use it.
Then I've upgraded the firmware to version 3.5 to try command AT+S.HTTPREQ, build my own POST header and be able to send data after the command.
In this way I've managed to send up to something less than 12 kByte. During transfer, the RTS signal is raised every 1024 byte so I inserted a pause to let the buffer flush. No matter how long I wait between the HTTPREQ command and the data (should I wait?) or between RTS signals (all of which stay deasserted for a fixed time of less than 3.5 ms and I've raised my pause time up to 1 s): when the data amount is 11460 bytes or more the packet won't reach its destination while with 11440 bytes everything works fine.
My current destination for testing is posttestserver.com, where I've found stored messages of several kBytes (even one slightly less than 1 MByte) so I assume that there's not a limitation on that side.
When the transmission fails the SPWF01SA1 doesn't say anything, I simply don't get the expected reply from the server.
I've also tried to split my single POST request into a sequence of AT+S.HTTPREQ commands (one for the POST header and one for just 32 bytes of data) but I couldn't make it work. Hence I assume that this splitting is not possible.
My question: is there a way with this module to send a 64 kByte block of binary data using a single POST request?
What is the recommended way to transfer large amounts of data?
Thank you.
