I 'm using a free account in order to test and evaluate the features and performance of the service.
From my device, using TCP socket I’m sending a single variable by using the RESTful API that is explained on the documentation.
I’m posting the variable without issues every 10s , and I found that after 100 successful uploads the server closes the communication .
I got this conclussion by sniffing the traffic from Wireshark, I got on my upload #100 a FIN-ACK request from server.
It sound to me to a free account limitation, but I didn’t find any reference of this, I already checked that at a cadence of 10s I’m still under the limit of 0.5M…
Do you know any limitation of data posting per minute, or hour ?
Did someone find same issue than me?
Hi this is not a limitation. The recommended use is to close the tcp and open it again. The server closes the socket automatically after a while to make sure it doesn’t leave open sockets.
@SantiOmron by default Ubidots in the same connection TCP allow only 100 Request, after the 100 requests are made, the connection is closed, this is because some devices have problems leaving the TCP connection without release memory.
Btw for the free accounts the maximum allowed is 6 req/sec.
Hi Gustavo!
Thanks a lot for your valuable answer, it clarifies everything on my case.
I’ll need to take care of that on my TCP client , managing the socket close-open from time to time .
