Re: Issue connecting sockets to some websites
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 ...

Re: Issue connecting sockets to some websites
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 -...

Issue connecting sockets to some websites
Hi, I'm using a fresh install of esp8266-1m-20210418-v1.15.bin on a ESP-01 with 1MB flash and I'm having some issues opening sockets to some websites. 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...

Re: Unable to upload files to ESP01
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.

Unable to upload files to ESP01
Hi, I've flashed an ESP01 with the latest version of MicroPython using esptool.py. I can now connect to it using rshell and Thonny, and can also use the REPL. 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...

Number of arguments for `micropython.schedule`
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...
