Hi dear,
i have tried to follow your procedure,
but what is the correct espRecovery sketch?
is this:
/*
* EspRecovery.ino
*
* This example works as a serial bridge between microntroller and wifi module
* (esp8266). It's very useful when upload firmware updates to the wifi module.
* It must be used only on boards where the connection between micontroller and
* wifi module is over serial, not spi.
*
* Note: this is a port of EspRecovery of the Arduino Uno WiFi Dev Ed Library.
*
* Circuit:
* - Arduino STAR OTTO or Uno WiFi Developer Edition
*

/*

#if defined(ARDUINO_STM32_STAR_OTTO) // Arduino STAR OTTO

#include <WiFiLink.h>

#endif
Serial.begin(BR);
SerialWiFi.begin(BR);
}
void loop()
{
while (Serial.available()) {
char inChar = Serial.read();
SerialWiFi.write(inChar);
}
while (SerialWiFi.available()) {
char inChar = SerialWiFi.read();
Serial.write(inChar);
}
}
How can install your firmware 1.0.0? by the normal procedure i have not your version choice, and i can not upload it.
kind regards

hey, sorry for the delay, iâm in vacation.
Be sure youâre doing all command line with Administrator rigth.
Step 1 install Python
Step 2 install the Wifilink Library in arduino
Step 3 only this way
Burn the firmware using EspRecoveryThis procedure is reccomended for all Operating System and it is usable only via Serial.
- First you must upload the EspRecovery sketch on your Arduino UNO WiFi:
- Plug in the Arduino UNO WiFi to PC.
- Open the Arduino.org IDE, you can download it here.
- Select the correspondent port and board.
- Upload the ESPRecovery sketch from File>Examples>Arduino UNO WiFI> Tools menu of Arduino IDE:
- Enter the board in bootloader mode:
- Unplug the Arduino UNO WiFi.
- Plug again the board to PC pressing the ESP B/L button.
- Open your terminal as Administrator.
- Download the ESPtool, you can download from here or you can use the command:
sudo pip install esptool
orpip install esptoolin windows
- Test the esptool, for example, inserting the below command to read the MAC address:
- python esptool.py -p your port -b baudrate read_mac
- Set the baudrate at 9600.
For linux user, for example, the port will be /dev/ttyACM0:
sudo python esptool.py -p /dev/ttyACM0 -b 9600 read_mac_
> For Mac user, for example, the port will be /dev/tty.usbmodem1411:
sudo python esptool.py -p /dev/tty.usbmodem1411 -b 9600 read_mac
For Windows user:
esptool.py -p COM30 -b 9600 read_mac
- If it will appear on terminal your MAC, then continue the procedure:
ConnectingâŚ
MAC: 18:fe:34:10:e2:85
> 7) Use this command to write the firmware but PAY ATTENTION to set the correct path and insert your correspondent port:
sudo python esptool.py -p /dev/ttyACM0 -b 9600 write_flash -ff 80m -fm qio -fs 32m 0x00000 20151223/boot_v1.4.bin_rep 0x1000 20151223/user1.bin 0x3FC000 20151223/esp_init_data_default.bin_rep 0x3FE000 20151223/blank.bin
For Windows user:
for example in case that the tools is in \Users\XXXX\Desktop\esptool\esptool\ folder and the COM is 30:
esptool.py -p COM30 -b 9600 write_flash -ff 80m -fm qio -fs 32m 0x00000 Windows example:
C:\Users\XXXX\Documents\Arduino\tools\ArduinoFirmwareWiFiLink\UnoWiFi\tool\bin\esptool-windows -p COM4: -b 9600 write_flash -ff 80m -fm qio -fs 32m 0x000000 C:\Users\XXXX\Documents\Arduino\tools\ArduinoFirmwareWiFiLink\ArduinoFirmwareWiFiLink-UNO_WIFI_DEV_ED-1.0.0.bin 0x300000 C:\Users\XXXX\Documents\Arduino\tools\ArduinoFirmwareWiFiLink\ArduinoFirmwareWiFiLink-WEB_PANEL-1.0.0.bin
8) Wait some minutes that the process ends.

Thank you for your explanation. I have no experience with MacOSX but its the only computer I have for now, so I have this problem:
I installed Python, I open terminal, I download EspTool over PIP but when I try to run its, it doesnât find it. I get this error:
Gonzalos-MacBook-Pro:~ espagnol01$ sudo python esptool.py -p /dev/cu.usbmodem1441 -b 9600 read_mac
python: can't open file 'esptool.py': [Errno 2] No such file or directory
But if I do sudo esptool.py -h I get this:
Gonzalos-MacBook-Pro:~ espagnol01$ sudo esptool.py -h
usage: esptool [-h] [--chip {auto,esp8266,esp32}] [--port PORT] [--baud BAUD]

What to do after esptool.py is finished
--no-stub Disable launching the flasher stub, only talk to ROM
bootloader. Some features will not be available.
So I know its a silly/noob problem like im in the wrong directory or something but I would really appreciate your help. Thank you very much for your time.
I fix it. I had to use for example:
sudo esptool.py -p /dev/cu.usbmodem1441 -b 9600 read_mac
instead of:
sudo python esptool.py -p /dev/cu.usbmodem1441 -b 9600 read_mac
I don´t know if its a version syntax related issue or what. Im a noob but it worked. Thanks!

I manage to to all this and to update the firmware to the latest one (20161121). But now im having problems to set up the Blynk app. With hardware should I use? Thanks.
@espagnol01 I donât have this hardware but as itâs an Uno (with an ESP shield) then you should select Uno in Blynk.
I have one quick question. When I run this command; âsudo esptool.py -p /dev/tty.usbmodem1441 -b 9600 read_macâ
I got this output:

Is this correct? Im I doing something wrong? If it hard reset itself, it means I have to disconnect and connect again in b/l pressing the button to run the next command? Thanks for your time.
This is the output after all:

This it look ok? Thank you for your time.â
Edit: After the flashing I canât upload any sketch to the board. I only get:
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 1 of 10: not in sync: resp=0x00
Any solution?
Looks ok, you asked to see the MAC and it gave you the MAC.
What does b/l mean?
boot loaderâŚmaybe?

the link in my previous comment earned me a âPopular Linkâ badge. For some months now, the link is obsolete and redirects to my new Uno WiFi Serial1 library and to my version of WiFi Link for any Arduino + esp8266.
And today I added a Blynk example to Uno WiFi Serial1 library and a Blynk example to WiFi Link library. Elegant and simple, Blynk
