PIC-WEB-BOX deployed as TCPIP <--> UART bridge

[ejphendriks@outlook.com]

I managed to get the Demo projects up and running.

As a next step I want to create a "TCP <--> UART" bridge that does not use the HTTP / Web server.
I want to strip the project down to just a basic transparent "TCP <--> UART" bridge?

Is there someone that has already done something like that?

What I want to create as a starting point:
- PIC-WEB-BOX acts as a TCP Server and listens for incoming connection.
- It should accepts only one incoming TCP/IP connection.
- When a connection is established it should act as a transparent bridge between TCP and UART.

What would be the best starting point for such a project ?

Hi Erwin, that board came with microchip libraries? (well, i think the answer is a rotund YES, but i ask just in case), you must congigure TCPIPConfig.h file for achieve your app.

Thnx Alfredosky,

I just figured that out by myself

I disabled every service using the TCPConfig utility and compiled the project again. Got 1 error:

Error - could not find definition of symbol 'You_cannot_call_the_SPIFlashInit_function_without_defining_SPIFLASH_CS_TRIS_in_HardwareProfile_h_first' in file 'Object\MPFS2.o'.
Errors    : 1

Will try again without the SPI...

I have a few questions about the TCP Config utility

On the first tab it offers the option Serial to Ethernet bridge (not TCP but Ethernet )



And on the following tab is speaks about UART_2_TCP_BRIDGE



Are these actually the same service?

And how can I specify a port number for the UART_2_TCP_BRIDGE?

I assume this UART_2_TCP_BRIDGE is bi-directional once a socket is open... Correct?

What do I need to select in the TCP Config tool to create a TCP Server (with a listen port) <--> UART ?

Any guidance would be very much appreciated because I can't find much about this in the documenation...

Thanks in advance

And finally I figured out that the TCP port number is 9761.

Now I can connect to the PIC-WEB-BOX from putty and that allows communication from the TCP side to UART side. So not in both directions...

Shouldn't that be possible ?
