Re: Sonoff Touch with ESP8285 and Micropython

At least it is smaller ;)

Have you got plans to fill the 2x 1,5 mm gap? Or is the part too small to fit into the mounting frame?

Re: WiPy v1.8.7 ( JAn&Feb) - SD reading issue

The was a change regarding the used FAT library and filesystem mount points. The maintainers should be aware of this but you can also file an issue on github.

Re: hiding python code on the board

To think that kind of security is easily implemented in an open source and hacker friendly environment is a false conclusion. It might be possible, but not well supported, because it is not designed into this platforms as it is on those Roberthh did outline. To be constructive... The intent you fors...

Re: Sonoff Touch with ESP8285 and Micropython

The ESP8266 boots up with 26 MHz oscillator and then has a 74880 for the initial boot messages (maybe internal osci?). Then after switching to 40 MHz this becomes the better supported 115200 baud.

So i'd guess that there is this 2880 multiplier, which might help!?

To proof kfrickes thesis, rename the AP ssid to something new and definitively unknown before and try again.
Of course this is the better way!

Re: connecting to open wifi access point?

I am just trying to lead to some details which might help us to identify resolve this issue... I presume this cache is in memory? I get the same results when attempting to connect after a reset or a power cycle No, the cache is in flash memory of your ESP board/module. I'd suggest you try to manuall...

Re: connecting to open wifi access point?

The ESP vendor API caches the SSID and password up to 5 different WiFi connections without further notice. It seems to do this in the way that when connecting with no (or an empty) password it simply (and quietly) looks up the last credential from the mentioned cache. Maybe you have the SSID in this...

Re: connecting to open wifi access point?

I did have a look at the sources (esp8266/modnetwork.c) and do not see any possible reason for that behavior. In both cases an empty string is passed to the underlying SDK method (wifi_station_set_config). A quick online search did yield some issues with the ESP SDK toolchain wich has had such issue...
