urequests with ussl causes an OSError #206

Closed Ahmedkalnaggar closed 7 years ago

Ahmedkalnaggar commented 7 years ago

When trying to get or post (to https links) every n amount of seconds using the urequests library it works fine and make around 10-15 successful requests then suddenly it raises an OSError -1 . And The Error points me to line 56 in the urequests code which is: s = ussl.wrap_socket(s, server_hostname=host) Normally I would catch any exception that occurs and try to POST it again or POST another packet. However, if an OSError occurs all the next Requests fails too which forces me to reset the board.

Sorry for the slow response on this... which board and version of MicroPython are you using? It may be that the device is running out of memory and can't create an SSL socket.

@dpgeorge I am working on WiPy 2.0 Board, I think you are right. Friend advised me to use gc.collect() but I don't know when should I use it. Could you confirm that might help ? or there is another better way ?

dpgeorge commented 7 years ago

If you're using a WiPy 2.0 then I suggest you report the issue at https://forum.pycom.io/ because the bug could be in their implementation of the ussl module (urequests in know to work well on other MicroPython platforms).

Closing then.
