Nothing is showing up. However, the blue light on the esp is flashing occasionally but no signal whatsoever from the computer.

Did you install the USB driver? Either your board is bad, or your drivers are bad. The ones with ftdi can suffer from fake chips, which then get bricked on purpose by the original ftdi driver. I have several Nodemcu boards, and they flash fine. This is an issue tracker for the core, and not the right place to ask for support.

The Most Easiest Way To Flash ESP8266-01

Please refer to a community forum. Closing per Same situation happened with me, I also purchased a nodemcu board of amica which is not showing on my windows platform. I had same problem but I solved it. My board flashed only flashed once it all about I think what my usb wire works but, pc still doesnt recognize it. So i installed like 1 thousand times drivers from silabs. But pc still doesnt see it and board still flashing. So i try to change my usb wire to another one, and pc recognized it So if yr pc doesnt see com port try ty change the wire.

Thanks to sshocked comment! Wire was the reason. Funniest moment is that I expierenced this problem before and forgot. Afterwards, it worked. Thanks SeppPenner. It's been a while since I've dealt with hardware and forgot about this. I've faced this issue quite a few times before and keep forgetting that some cables don't offer a data connection.

It's now working fine Same problem in the end was the change that does not have to pass data, was a cable for cellular charge, so I lost an hour in search of the solution.Pages: [1]. To test it I've got a second Arduino send periodically a msg but it also echoes any incoming msg.

This works great if I connect the Arduino directly to a computer but if I bridge the serial connection via the second Arduino which is in a tristate only the periodic msg comes through and echoing doesn't work anymore. I can't explain this behavior at all, my actual intend is to control a ESP via the Arduino IDE Serial monitor but this won't work either since I excpect the msgs don't come through to it.

Has anyone encountered such a behaviour? It also happens if I switch the Arduinos jobs Echo code: Quote. Now with Unlimited Eagle board sizes! Why Serial. Hi CrossRoads!

Thanks for your answer, I just changed it but the message doesn't get echoed back either. I just noticed you are putting 5V from the USB connected board into Vin on the 2nd board - that puts 5V into the 2nd board's 5V regulator, which will produce a low voltage to power the board. Try connecting 5V to 5V instead. Quote from: CrossRoads on May 25,pm. Nope, that still didn't fix it. I'm really not worrying about the power supply anyway since my actual goal is to talk to a ESP via the Arduino Serial chip.

However I can't get any data through the Arduino bridge in both ways, I can only receive. The echoing doesn't work and I have no idea why. I'm not sure what the issue is. They work great, the 3. These are, IMO, the good cheap ones - they've got a switch for 5v vs 3. They even include free F-to-F dupont jumpers, not that that's what you need to connect it to an Uno. Not gona work.

Quote from: ltheoret on Jul 05,am.When I look at the properties of the driver, it is showing This driver cannot start code What could be the reason for this.? What OS are you running?

I recommend you make sure you have all updates installed and that you are using the latest version of the driver. You may also need to reboot your computer, or uninstall and then reinstall the VCP drivers. Are you trying to install a customized driver from the manufacture of this product? Please contact with the producer of this product to get the customized driver.

You know what solution could I apply? Replied Feb 08AM. Do you have separate power supply to power the board? Do you mind upload the schematic of this board pdf format preferred. My views are my own and do not necessarily represent the views of Silicon Labs. Replied Feb 08PM. You could also try the ANSW to customer a driver to confirm if this is the issue. Replied Apr 16PM. Thanks, Spurthi. Correct Answer.Now, follow the flashing guidelines available in Readme file according to your ESP edition and set the bin files addresses according to your module memory size.

Now, you should see the home page. Image Courtesy of ElecFreaks. Finally, I think a considered amount of time is needed to explore the other options of this amazing project! The next step is to get the compilation tool-chain xtensa-espelf by executing one of the get. Now, testing the compilation of a simple program is needed also. The following test code can be used.

Image Source: Aliexpress. Many things can be configured before uploading the code to ESP32 like choosing the working mode as a station or an access point and many other things. Do you need to know more about ESP32? Yes it is doable, but there is a need to write a code for ESP to advertise an Access point to make the client connects to.

Thank you very much for this. How do I use this to display my programatically generated debug serial messages from my sketch? Typing in the wifi and COM terminal windows work as expected, but the messages that my sketch sends to the COM terminal is not mirrored in the wifi putty connection. Hi, I tried something like that but I blocked on some limitation. What can I do to make it better? Maybe on IDF? Thanks for your help.

I tried your project on ESP In config. There was a problem when transmitting large amounts of data. The first 12 kB file is transmitted normally. Then, after a pause, the same file is transmitted with errors. The further you gothe more mistakes you make.

Then it stops transmitting even single bytes at all. It looks like the memory is filling up somewhere and not being cleared. Can you help? A very necessary device. Your email address will not be published.

WiFi-UART Serial Bridge Using ESP8266 or ESP32

Note: Telnet connection can be done from a smartphone by using Telnet client application like Termius or any other working application.Mains Voltage is dangerous for you and your computer! Always use a separate power supply. You obviously need a device with ESP They are the most easy to handle version of ESP For other devices you need a power supply with 3. It will kill the chip.

It's recommended to get an assorted bunch of such cables as you may need them to connect sensors, actuators and such for testing. Buy cables with many different colours.

It helps We have seen some strange behaviour from cheap power supplies. If you put a voltmeter on these it shows the correct voltage. Everything looks nice. Use a high quality power supply like MeanWell or similiar.

It should have at least a current of 1 ampere. With some UART cables a wire has to be soldered accordingly. The FTDI might be one of the most faked chips at all. The genuine manufacturer took measurements against these fakes. They will not work correctly at least with Windows. Everything looks fine, apparently flashing worked well.

You can use several different softwares for flashing the ESP. It needs no settings and works just out of the box. ESP Easy is programmed to give information via the serial port, the same port you use for flashing. Of course you need the ESP Easy firmware.

Also unpack the two EXE files. Everything is ready to use on these boards. The ESP usually starts up from the internal flash that contains the firmware. For flashing the ESP it must be set into "flash mode". Said simply this starts another program at bootup, reading the serial port and writing the data into flash memory. The ESP has four inputs that manage the startup behaviour. These setting are necessary to flash the chip!But what do you do if you need to flash new code into the microcontroller?

The solution? By flashing the esp-link firmware into your ESP, you talk directly to the microcontroller over WiFi as if it were connected by a serial cable: the ESP becomes a totally transparent WiFi-serial bridge. Now, with a serial bootloader and an ESP in Wifi-to-serial bridge mode, you can reflash your microcontroller wirelessly, and then telnet in to interact with and debug the system remotely.

And then after that you can simply telnet to the ESP at port 23 and type away, or do anything else you would with a wired serial connection. In addition to the serial bridge code, there is also a REST-based microcontroller-to-internet mode and there is bi-directional MQTT support in the wings.

For the most up-to-date development news, follow the very active development of esp-link in this thread on the esp forums. Not only this, it also makes a RSWiFi bridge for a fraction of a commercial cost — just add a transceiver with direction auto-detection. You could always buy routers and flash them with Openwrt and add a package to be used as serial over IP. Add a box and power supply to your ESP and you will not save that much, if you still want to stay with the same application.

Different applications call for different approaches, of course, but it is not like before the ESP you could not get something on-line for reasonable low cost. Maybe this? Such a board would be truly Kickstarter-worthy. Hackaday, when are we going to get an edit button? You have some of the best minds on the planet reading this blog, surely you can find someone capable of doing a little PHP scripting for you….

Why not just use the ESP itself to run your application?

Can the ESP do it? There is your answer. Myndale I remember seeing some not arduino user so i did not bother remembering where but my best bet is that you can make a simple pcb to connect the 2 together.

Anyone want to help make this happen let me know!!! Thanks for posting! I actually was getting ready to duplicate this capability tonight. Glad I procrastinated and checked hackaday first! Using it on an evaluation board to test out the BNO on a robot.

This will let us evaluate the sensor and monitor data remotely, real-time witout having to write any code for our ultimate target. I believe that most tools on the list are for redirecting physical serial port existing on the system. What is needed is a tool that create a new virtual serial port on the system. I for one avoid links through such websites. I can understand the need to advertise the site, but using url shorteners is usually seen in a bad way spammy in comment threads and when I see one I just avoid clicking on it.While it is popular, there are some works needed to integrate it into your project as the pins are limited and is not beginner friendly.
