BUG in activating network interfaces

I think there is a bug in activating sta/ap interfaces. When running the script below, ap_if.active() wil continuously print False. However the bug will only appear with sta_if configured with SSID and pasword for your modem/router and with ap_active deactivated on start of the script. If ap_if.acti...

Re: OTA Firmware update with pure uPy script possible?

Think that is a ESP32 only feature... Arduino has OTA updates on ESP8266: https://arduino-esp8266.readthedocs.io/en/latest/ota_updates/readme.html But I don't know if that will replace the complete firmware or only the user code? The ESP8266 has FOTA (Firmware Over The Air) build in since day one. ...

Re: Build how to?!?

I think the whole build procedure with 'open-esp-sdk' for the esp8266 should be updated. 1. It uses SDK-2.1.0 which is from 2017, so almost 3 years old. Even the latest version 3.0.0 will not be updated anymore. Espressif will only supply bugfixes for 3.0.0. 2. Also Espressif advise to use the 'ESP8...

Re: How to move from pyboard to PCB ?

Have a look at KiCad https://kicad-pcb.org/

With KiCad you can make a schematic diagram and convert it to a PCB.
Some manufacturers can use the kicad file directly otherwise you have to export it as a Gerber file.
There are plenty of youtube examples how to use KiCad

Re: Can build and flash, doesn't boot

I had the same error when I tried to flash a esp-07 which had 1Mbyte flash while I expected that is was a 4Mbyte device like most esp12-F's.

Re: Working with ESP8266 (ESP-07S)

This is the Micropython forum. Your code is C.

But your problem is that you should use the GPIOxx names as pin and not the physical pins of the board.

Unfortunately this is an ESP32-only feature and not currently documented. https://github.com/micropython/micropyt ... rtc.c#L128
That is not true. It is implemented (and undocumented) for esp8266 too.

Re: How Should WiFi Passwords be securely stored on micropython device?

So you should prevent this by cutting off the pins that connect to tx/rx, fill your device (especially also the flash memory) with epoxy etc. What exactly do you mean with "epoxy" etc. ? I never heard about this term in this kind of area. I mean like 2 component epoxide glue. I have to say! This is...
