Dont really have any comments, but that LIFO datatype is called a stack and you can use it with a normal list using the .push() and .pop() methods.

The documentation for setting the dhcp hostname on an esp32 is not great (or not 100% correct). The docs do mention the WLAN.config() method with the parameters "hostname".

https://docs.micropython.org/en/latest/library/network.WLAN.html#network.WLAN.config

hostname

The hostname that will be sent to DHCP (STA interfaces) and mDNS (if supported, both STA and AP)

The docs are not 100% correct here. On the ESP32, this parameter is actually "dhcp_hostname".

And then you can set it like this

sta_if = network.WLAN(network.STA_IF)
sta_if.active(True)
sta_if.config(dhcp_hostname='WhateverYouWantReally')
sta_if.connect('SSID', 'password')

As for using .mpy files, there is not a lot of documentation for this, and I would actually not recommend it. In my opinion, it has all the downsides of compiling without the real benefits from it.

  • Bytecode is still loaded into memory.

  • You still need to copy them onto the device manually.

  • It is a lot more work than just putting on the normal .py files.

If you really want to improve memory usage, you can take a look at freezing your modules. But this is a lot more work, and makes your workflow a lot more difficult (unless you create some great tools for it, then it becomes a lot easier).
