[Solved] NEW Arduino UNO WiFi board

Hi there,

I was able to read and write to virtual pins with the examples posted above.

But I have a problem reading a time input widget from the app. I get back only 4 characters from the ciao read function. If i test the get command with the browser I get a lot more of data.

Has someone the same problem and has a solution?

Thanks in advance!

@ffutsi start a new thread in the “Help with my Project” category but provide all the information we need to be able to help you (hardware, software, iOS / Android, sketch etc).

Is there any indication yet IF/WHEN the Uno WiFi will be fully adopted by Blynk?

I too have had some success using the Ciao methods above, but I too am seeing substantial delays when writing values to Blynk, sometimes greater than 15 seconds. (I call my Blynk routine via SimpleTimer, and I’m only pushing two values every 500ms, so I know it’s not an issue with flooding.)

Any delays more than 1-2 seconds make this construct totally unusable for my applications. Would love to have full Blynk functionality for this board. Any info is appreciated!

Any update to this? I have a system I’ve designed with the Uno Wifi, and will be commercializing it soon. Would love to be able to integrate Blynk into the product offering, but I don’t know if adding full Blynk compatibility for the Uno Wifi is even on your roadmap…?


@vshymanskyy would be correct person to tag here :slight_smile:.


Thanks Dmitriy.

Vhymanskyy, any idea if native Blynk compatibility for the Uno WiFi will happen in the near future?

No, we don’t support this board. Anyway we really welcome any community members willing to work on supporting this board.

Thanks. I realize there is no current support, I was asking if there are any plans to support it in the future? I guess the answer to that is no?

I suppose if you contact them on the business side, they might be able to work something out.

Thanks Gunner, not a bad idea. Probably easier/cheaper to just switch to a different MCU though.

Anyone know of an Arduino-based board with onboard WiFi and multiple Analog inputs that is natively Blynk compatible?

We started with Arduino Uno with esp8266 attached, but that turns into a bulky solution with the external 3.3V power regulator, 3v->5v logic shifter, and mini breadboard.

Have also used the WemosD1 R2 with onboard WiFi, but our system requires multiple analog sensors that run on 5V logic, so an external 5V regulator and logic shifter is needed in this case too (plus the Wemos D1 only has one Analog pin).

That’s why Uno Wifi seemed like the perfect solution (Wifi on board, 5V, multiple Analog pins)…it just isn’t fully Blynk compatible.

Any suggestions?

Most of the off-the-shelf boards are really meant as development boards, thus too few or too many options depending on target market.

So unless you are literally out of your garage, when going to a commercialized product it might be better to roll your own circuit with the MCU, WiFi and any logic shifting integrated into a smaller customised layout.

Perhaps hire this guy to make it for you :wink:

Oh yes, absolutely. We’re just not that far along yet. We are merely looking for a easy to replicate prototype to widen our field testing, which is why we’re still looking for off the shelf options.

I’ve seen an Arduino Mega board with integrated ESP (attached to serial port) on one board. They are not very cheap (think 25 bucks), but they look like a nice board to develop stuff on. It’s this: http://www.ebay.com/itm/222305385421 thing

You can set the connections with jumpers. E.g. wether USB<> Serial is attached to Arduino or ESP or something else. I’m hoping I’ll receive this soon for testing. Looks likes a very nice all-in-one solution for developing. Only thing missing is an Ethernet port integrated :wink:

Check this one…

ATmega2560 R3 Mega WiFi ESP8266 (8 Mb de memoria), USB-TTL CH340G. Compatible para Arduino Mega, NodeMCU, WeMos ESP8266
(from AliExpress Android)

Yeah, I found that too, but allas, I don’t have a CC, so I cannot buy at Ali :frowning:

I’m using Blink on a wemos D1 mini with no problems. I would like to use Blynk on my Arduino Uno board with w51000 shield for Wifi connection, seems to a bit harder to do. Any help doing this would be great! Thanks!


That looks like a very interesting board. When you receive it, will you please report back and let us know how well it’s working with Blynk?


Good find, even cheaper! Have you used one, any idea how well it works with Blynk?

I’ll definitely report back. I’d like this for my main domotic system. I had all sorts of loose wires in there from ethernet and wifi and so on :smiley:

This saves a lot mess.

The DigiStump Oak can be utilized with the Arduino IDE. It has the WiFi you want and DigiStump has a Blynk library included with the Oak Arduino libraries.
The current level of the firmware has stabilized the WiFi connection and mine has been sending me Temp + Humidity data via Blynk for about 15 days since I last updated everything.
DigiStump has both 3.3v Relay shield and a level Shifter 3.3 to 5V shield to facillitate interfacing to 5 V devices. The Oak accepts 5 V in and provides Vin and 3.3V Vcc outputs.
DigiSTump Oak or cruise the Wiki or the forums: [Forums]

I have used virtual pins, read analog in, virtual LEDs for status etc in controlling a Hi Fi remotely via Android app. The Oak is 1/3 the size of the UNO but the shifter shield in a bit larger than the Oak.
Other shields are available.
Certainly meets many of your needs as a rapid functional prototype candidate. Fairly cheap too.
