I have downloaded Arduino IDE 1.8.5 so I can use my Arduino Uno R3 WiFi board I have also updated to the latest version of Blynk i have followed all the instructions posted by
Still struggling to to connect to the net
I donât see any Blynk-related problem here.
@oldvolt the GitHub you linked to has this instruction:
AT+UART_DEF=115200,8,1,0,0 - setting of the default baud rate
Blynk sketch when using super slow Arduino and ESP shield system needs to be 9600 baud. So change the AT command to 9600.
@oldvolt why do you use AT firmware and not WiFi Link? scroll to next chapter in the Uno WiFi Dev Ed Serial1 doc
If Serial1 is being used by Blynk as a WiFi shield to a super slow Arduino like an Uno then the baud needs throttling down to 9600.
It has nothing to do with Blynk. The WiFiEsp library works on Uno WiFi over itâs hardware Serial1 at 115200. With one small modification in the library. But here the WiFiEsp library doesnât see the firmware at all. (I am the author of the Uno WiFi Dev Ed Serial1 library).
OP mixes things and who knows what he has in the esp8266. I recommended to him in other thread that he should install WiFi Link.
both. because the library implements the uart bridge chip that connects the Atmega to esp8266 on Uno WiFi board, in Wiki of the project is everything about Uno WiFi Developer Edition
@Juraj fortunately I donât use anything nearly as complex as the Uno WiFi 
From what I can make out itâs a case of users not following the instructions in the docs, like Blynk, and your library fixes some of the shortcomings of the hardware, right?
The library opens full potential of that great board. I experimented with esp serial modules with spi connected Wemos, but Uno WiFi is the best choice. Everything is connected on board. The additional serial keeps Serial0 free for USB flashing and Serial Monitor The Serial1 is fast enough (230 400 baud). You can reset and program the esp from atmega and reset and program atmega from esp. If you want you can open a direct connection from esp to Serial0 of the Atmega and bypass Serial1. All this with software without touching the board.
Whatâs the best available price (and url) for this great board?
Price was around 40 âŹ/$. Now out of stock everywhere. Should be again on stock in some weeks, but I do not know if it will be the Developer Editon or a new Standard Edition with esp8266 connected over SPI.
Ah so the developer edition is different to the regular Uno WiFi.
I was looking at the $10 âUno WiFiâsâ available from the Far East and hoping they might have the âdeveloper editionâ features.
At $40 and no stock I think itâs a none starter for many users.
Jura and all thanks for the replies
Because of my limited brain I assumed that I had to install all firmware from the links that said I installed Arduino 1.8.5 IDE I also installed WiFi link that came with 1.8.5. and still no luck but I am going to try again with the links from the original post
Is there any way I can set the Arduino UNO Wifi back to factory settings so I can start everything afresh
I must frustrate members with my questions but I like trying to use Arduino and Blynk while listening to my favourite Glasgow football team trying to challenge the elite football clubs in Europe like my team I will never get anywhere near the elite members of Blynk but I do get much enjoyment out of trying
Kind regards and thanks to all

only follow the chapter âUNO WiFi with WiFi Link firmwareâ in Uno WiFi Dev Ed Serial1 github repository page and the links in that chapterâŚ
Here are some Uno WiFi and WiFi Link troubleshooting sessions with girls on arduino forum:

for now only the âDeveloper Editionâ was manufactured. the price is very good compared to original Uno with original WiFi shield.
the Robotdyn Uno + WiFi has esp8266 on board but the only connections are RX/TX configurable with switches. the Mega + WiFi can use Serial3 of Mega. that is usable.
I guess for âmoon landerâ style iOT projects then your library is very useful i.e. when you need access to the dozens of pins on a Mega.
For most projects D1 and D1 Miniâs are probably all that is needed and for a very modest cost.
Still waiting for that Moon Lander widget to become available on IOS, but then Iâd have to fork-out $$$ for one of these boards. Maybe Iâll just stick with the Wemosâs and forget the intergalactic stuff for now.
Pete.
Anyone that can afford iOS can easily afford $40 for a decent development board
