An update from my research: According to this Github thread , this issue might be due to the fact that the AXTLS library doesn't support ECDHE ciphers. This makes sense as the site that's failing for me indeed uses the following: nmap --script ssl-enum-ciphers -p 443 www.wikimedia.org Starting Nmap ...

Thanks for your reply. Regarding the two issues: 1) OSError: (-257, 'RECORD_OVERFLOW') I saw in this thread on Github that this was due to a SSL buffer overflow. So as suggested in that thread I rebuilt Micropython with "-DRT_EXTRA=8192" (Note: I'm using a ESP-01 with a 1MB flash size): docker run -...

Just a friendly bump

If someone has some clues on how to address this, please let me know. Thanks!

Here's the basic code: def socket_connect(hostname): addr = socket.getaddrinfo(hostname, 443)[0][-1] s = socket.socket() s.connect(addr) s = ussl.wra...

Thanks for your reply. My flash size is 1MB. I realized I had installed the wrong Micropython binary. I then installed the one for 1MB boards and it's now working as expected.

However, I can't seem to be able to copy files to it. With rshell I get this error: cp client.py /pyboard Copying 'client.py' to '/pyboard/cl...

Hi, The signature of `micropython.schedule()` is `(func, arg)`, i.e. it takes the callback function and a single argument. Is there a technical reason why only a single argument is supported? I have a case where I'd like to pass multiple arguments. I resorted to grouping all the arguments into a tup...
