Is your .bin file for an ESP32?

Wwafa_ath Is your .bin file for an ESP32?

AbdullahOP•10/22/24, 5:26 PM

The file names BlynkNCP_uno_r4_wifi.flash.bin

https://docs.arduino.cc/tutorials/uno-r4-wifi/esp32-upload/#hardware--software-needed

https://github.com/Blynk-Technologies/Blynk-NCP-Driver/issues/7

Here they explain it but I don't know python nor platformIO can you help me please

Once you login to your Blynk dashboard (web version). Please check in the left pane where you'll find

Hi, I found this interesting project in github called "Auto Jobs Applier AI Hawk" It automates the job application process using AI, making it easier to apply to multiple jobs with less manual effort. It can help you streamline your job search and save a lot of time.

If you’re actively looking for jobs or just want to speed up the application process, i think you should give it a try

I did everything written but still the same error

I have an arduino uno R4 wifi board. I want blynk ncp to work on it, but this error always appears and I don’t know what the solution is. Please help me.

wafa_ath•10/23/24, 5:30 PM

If u did as they say it may be a path problem ,
Chek if the Blynk.NCP library is installed in the correct folder. It should be located in the libraries folder of your Arduino IDE directory (typically Documents/Arduino/libraries). And run the IDE as administrator

Umesh Lokhande•10/24/24, 2:28 PM

Let's break down the issue into smaller steps. Have you succeeded to control and monitor Arduino Uno R4 Board from a Blynk dashboard (without Blynk.NCP)? Also, could you please tell us, why you think Blynk NCP library can solve your problem? If it's just about OTA, you wish to achieve because it's possible to update firmware, means changing wifi ssid and password without using Blynk.NCP via OTA. Please provide more background details.

AbdullahOP•10/24/24, 8:17 PM

Frankly, I have not tried running the board on the Blynk platform only without Blynk NCP, and the reason I chose this library is the (find device nearby) feature, as it makes it easy for the user to change the Wi-Fi network with easy and quick steps.

AbdullahOP•10/24/24, 8:24 PM

I have tried esp32 before on blynk edgnt and the process was successful but the esp32 ADC is not accurate in reading so I had to add ADS1115 but that is the reason there are many parts in the project so I bought the arduino uno R4 wifi because it is accurate in readings and has 5V and contains wifi but it cannot be linked to the blynk edgnt library but rather it is linked to blynk ncp and now it is stuck in linking the arduino uno R4 to this library (blynk ncp)

Umesh Lokhande•10/25/24, 7:49 AM

Ok, I get your point. But as a frequent user of Blynk. I'd like to inform you Blynk.NCP is a relatively new feature. And, I'm not happy with its documentation and git repo. Don't expect things to come easy if you're early user. No doubt the feature is cool for retro-fitted and co-processor scenarios.

Still it worth using

#include <WiFiS3.h>

#include <WiFiS3.h>

library with Arduino R4 and make things working with Blynk.Air (OTA). Meanwhile, you can try and follow this https://github.com/Blynk-Technologies/Blynk-NCP-Example-Arduino

I was using a loop and writing all byte of eeprom to 0

maybe check that your loop is doing the correct thing at each iteration

wafa_ath•10/26/24, 6:47 AM

I noticed that during this office hours , when we touched on embedded AI, both Mr. Ming and Umesh didn’t seem particularly excited about . It made me wonder – is embedded AI truly a transformative trend, or is it just hype that everyone’s following?
What does everyone think? Are we just equipping devices with AI tools for specific tasks, or are we witnessing a shift where embedded systems and AI converge into a new design philosophy, and as embedded systems field is it really worth the time, effort, and resources to dive into it fully?

Umesh Lokhande•10/26/24, 7:45 AM

If i recall correctly the question to Ming was more on the device side. And the application area was Edge AI. I don't see AI as hype but gradually evolving field in different areas from edge devices to Embedded IDE's like Embeetle, PCB CAD softwares. I feel the investment of time in learning AI makes a lot of sense if one knows the exact problem they are trying to solve. I'm excited to hear about AI with FreeRTOS in the upcoming Engineering Hour by @ZacckOsiemo
