B4R Question ESP8266 OTA updating

[Brad]

I was wondering if B4R supports OTA updates or would I need to use the Arduino IDE.

 

[Cableguy]

can you elaborate on this?

I don't think the board itself can handle OTA Updates...

 

[Brad]

It does support OTA. The official docs describe it but I don't have it handy right now. Here's a link showing examples using Arduino IDE.

 

[Cableguy]

Very interesting... Is that firmware version stable and available?

 

[Brad]

I'm pretty sure it's available as I see several examples but not sure how stable. With this option a requirement for my project I'll be finding out.

 

[Cableguy]

Do keep a separate thread for how to upgrade the firmware. I bet there's a lot of users interested in this as I became too.
As for the question, as f now, no, B4R cannot (yet) do OTA... You should add it to the wishes subforum

 

[Brad]

I will add it to the wish list but in the meantime I guess I'll be going back to using the Arduino IDE for development.

Note that you can program with B4R and deploy with Arduino IDE. Just load the src.ino in Arduino IDE and run it each time.

You can select an invalid port in B4R.

Great to know Erel! I'll post on my results.

After further research it appears that the Arduino method won't work. My modules will be remote so I will need to use the http server OTA method.

One thing in the linked page - "Flash chip size is 2x the size of the sketch."

Kolban explains that you only use 1/2 of the flash. Your OTA upload goes to the unused half and then you switch to it for operation.
