Supported cipher-suites on the ESP8266

The latest updates to certbot from Let's Encrypt have presented a problem for my micropython-powered esp8266 due to the incompatibility of cipher suites, which now supports the recommended set listed here: https://wiki.mozilla.org/Security/Server_Side_TLS#Intermediate_compatibility_.28default.29 Aft...

How to workaround the file system becoming corrupt by interrupted file IO

I have a little IoT device that stores key/value pairs in the file system. The device will read/write to this store at regular intervals through the day. I have noticed that if the power is interrupted during this IO, the file system becomes corrupt (in the same way as described here: https://forum....

Re: How to know the IP address

I am now going to use https://github.com/nickovs/slimDNS - this allows me to connect to my device with a friendly name, rather than trying to figure out what the IP address is (as long as the host's device/router supports mDNS).

Over the air firmware updates

Hi,

For my WiFi-connect IoT project, I am freezing my python code in the firmware and flashing it to the device. I do this to alleviate RAM issues.

Best practise for setting up a device with static files

Hi, I have a Wemos D1 Mini that broadcasts a little webserver. All of my Python files are frozen and combined with the firmware, which makes it super easy (and efficient) to setup a device. However, the HTML files need to be copied over manually, which means setting up the WebREPL temporarily to per...

How to know the IP address

Hi, I'm using MicroPython on a Wemos D1 Mini to power a little IoT device. When it is first powered, it will power-up its WiFi access point for the user to connect it to their home WiFi network. I have some questions about what IP address the user should use both when connecting to the access point,...
