This is a work in progress.
- TLS doesn't seem to connect
- interfaces need some work, especially around correct nsapi_error_t codes
A wrapper for client mode.
- TX, RX, and URL buffer sizes defined by template
- blocking interfaces that behave like the regular socket classes
- TCP or TLS mode determined by URL
- no need to create/destroy for each connection
An example:
#include "wic_client.h"
#include "EthernetInterface.h"
int main()
{
enum wic_encoding encoding;
bool fin;
static char buffer[1024];
nsapi_size_or_error_t bytes;
static EthernetInterface eth;
static WIC::Client<sizeof(buffer)> client(eth);
eth.connect();
client.connect("ws://echo.websocket.org/");
client.send("hello world!");
bytes = client.recv(encoding, fin, buffer, 100);
if((bytes >= 0) && (encoding == WIC_ENCODING_UTF8)){
printf("got: %.*s\n", bytes, buffer);
}
client.close();
}There is one configuration item called wic.mss. By default this is
set equal to lwip.tcp-mss. The WIC wrapper uses this value
to ensure that no more than one segment of data is written to send()
at a time. Writing more than one segment will cause LWIP to perform
IP fragmentation.
No support for this mode at this time.
Clone the WIC repository into a directory in your MBED project.
The .mbedignore file is written in such a way that the right sources
will be found by the build system.
