Updating OTA is amazing

150

Yes, that’s the idea!! :relaxed:

151

Or you can go the httpupdate route like I did and have it check for an update every time it wakes.

152

What’s that like on the battery life?

153

No clue. It is just checking a server to see if the file exists for update then moves on. I imagine it wouldn’t impact it much.

154

Would this work with wemos d1 mini? What about arduino nano with ethernet shield?

155

Certainly works for WeMos D1 Mini. It would be a different library, if one exists, for ethernet “OTA”.

156

Can anyone help me with code and library for ENC28J60 with arduino nano? OTA works great on my WeMos D1 (old version), but for me it will be more important to be able to upload sketch without physically accessing my board that is connected to ethernet.

I am using this code:

@monaco take a look at this very, very, very long page that details updating Arduino’s over a network, not OTA as Arduino’s don’t have “air” access http://www.freetronics.com.au/pages/how-to-upload-a-sketch-to-your-arduino-via-a-network#.V8yBCvl9600

158

A word of caution, it’s very complex. I’ve been trying for a couple days and I gave up, lol. It’s just easier to get a Wemos :wink:

Uf, complicated :slight_frown: From network perspective it is not important if connection is ethernet or wi-fi, so this “air” should not be considered literally :wink: IP address is IP addresss. That’s why there is idea to use this option. But I have no idea what would need to be changed. Probably different library…

160

I just want to say thank you to everyone who contributed to this awesome thread. OTA update + Blynk is working perfectly on my NodeMCU v2 + Arduino IDE 1.6.11 (and esp library 2.3.0)

Just wondering if you had any issues with arduino 16.11? I had issues with going from 16.9 to 16.10 but should i be fine with the new one?

162

Usually it’s full of bugs, so I’d keep a copy of a working version handy, other than that, it’s just a matter of trying, I’m afraid :slight_smile:

163

@Dave1829 haven’t had any issues with it thus far :sunglasses:

I could do my sketch with Blynk and OTA. I used your code by exemple! Thanks Roccod!

165

was your RTC widget OK?

166

I’ll find out this weekend :wink:

167

OMG, I read almost everything but no clue what is happening :rolling_eyes: but if someone provide an instructables with pictures and video would be awesome… Am I expecting too much? :upside_down:

168

@speed57 the secret is to read all, not almost everything. In answer to your question, yes.

Read, read again and then when you have read it again and tried everything tell us everything you have done, all the hardware and software you are using and what results you get.

We might then be able to point you in the right direction.

Thank you guys @Jamin, @Costas , @Lichtsignaal always good projects, sharing codes and support for community :pray:
