I have designed a data logger board based on ATMEGA644 uP and W5500 chipset.
The goal is to measure 8 temperature sensors and send the data to a server, every 1 second.
I get a connection with the server alright but not sure about the way of handling the socket for continuous SEND() commands (sending a packet of 64 bytes every second)…
Data received by the server is not “clean” and has a lot of “nonsense” material addd to it…
I am “new” with the W5500 and any advice will be appreciated…
Thanks
Dan
I hope you refer to ioLibrary_Driver.
Implement the send() function in socket.c in your environment, and call the send() function every 1 second counts.
Hi Becky:
I am glad to see your reply and
I would like to have a "channel " to the Wiznet team because I got stacked in developing a project to a client in which I have to send a packet of data (constant size) of sensors every 1 second!
I have designed a special board for it using the W5500 and got to have a connection with the server but data that I send (small string, once, right now) is received with “milliard” of junk bytes and the data itself appeared few times. I am using the iolibrary routines as is to handle the socket, connect, and send activities.
Is socket can be open “forever”? Keep Alive needed?
Becky hi,
I am sending TCP string to host server (len =0x96). I am getting allot of “garbage” before seeing data on screen.
Before sending the WR pointer is ox00FD, after sending it 0x0093, but must be 0x0193 (0x00FD+0x96).
Is that my reading mistake or sending the hole buffer and wrap around to address 0x0093?
Please respond…
Regards
Dan
