Thanks for the feedback, very much appreciated 👍

Interesting, thanks for the info 👍 powering it from the Pico would be much more convenient

@@tinkertechtrove2910 Mine worked etting the 3.3v from pico too, however I have to connect the 3.3v after the pico start running, It does not work if it is already connected to the power when pico starts to runnig. Not sure why. I will try get the 3.3v from some pin after 1 sec pico is running by turning this pin to high.

Glad your enjoying the uploads 🙂 good luck with your ESP01s. Making a WiFi extender would definitely be an interesting project, or maybe even a mesh network from several nodes spread around

@@tinkertechtrove2910 Worried you have something place inside my brain, maybe a pico relying information haha but also was thinking of a Mesh Network, considering I have 4 of them to play with (just £12!) Hey do you know in your video if you version is EPS01 or ESP01s? I don't really know the difference myself, I teach just software on youtube with Godot, I'm hoping to interface pico or arduino with it though for some entertaining situations

I'm really sorry Tim, I have just one last question, I LOVE that this channel so far is raspberry pi pico, I think it's gonna be huge and 100% the right direction to go. But will you feature Arduinos in the future? Even if it's only how to interface with a Pico in some way, it's exciting for me.

Of course, the Arduino is also an excellent board. I have used it with Grbl for DIY CnC projects, probably going to be doing some uploads around that at some point.

Thanks for the feedback, I am trying to improve that. 👍

So long as you use a voltage regulator, buck converter, or something else to make sure the voltage is 3.3v then it should be fine. I will be exploring ESP01 low power modes soon as well.

@@tinkertechtrove2910 Ok thanks Tim. I am new to electronics. The battery pack works well, tried using a usb power bank which turns off after a few seconds. I guess the pico is not drawing enough power. The bluetooth module only works when when pico is connected to my notebook. If I can get the EPS01 powered by battery I will be there ! Thanks again Tim.

I have not tried, would be interesting though

Do you know if we add a script to ESP01 like the example in the video, which I did, the original firmware is deleted? BCS I spent 2 days just trying to send an AT command to get the OK back but I had no success. That is why I tried the approach of the video. I tried to see some videos on how to install a firmware, but it seems very complicated. I think, when we add some script in the esp, the firmware stops working, BCS it only runs the script

@@alexdominguess Yes it wipes it out. You will have to download again and reflash.

That's probably possible, though I have not tried. You can use an Arduino as well, there are tutorials for that online

Seems you have some data in the buffer (rxData) that can not be decoded using utf-8. You could try waiting a bit before reading data as the ESP-01 sends some binary on startup, or better yet check out part 2 for a much better way to do this ukposts.info/have/v-deo/ro-FoZWAnpiDpZc.html

@@tinkertechtrove2910 Thanks. I love your video. These videos are extremely helpful. Best wishes.

Damn I didn't see this comment, I just posted it myself, I'd LOVE to see this.

same problem :(

Yep

Yes but the ESP8266 is smaller and cheaper, especially as an ESP-01, which is probably the cheapest ESP-Anything that you can buy that's not just a bare chip. I also suspect that the ESP32 uses more power also, although theoretically (with the right firmware), you'd get access to the latter's Bluetooth functionality also. The new ESP32-C3 is intended to be a new-and-improved replacement for the ESP8266 and has already started to be made incorporated into ESP01-compatible boards, so that's another potential path to Pico Wi-Fi happiness. And as of a few days ago, there's the Pico W which provides similar functionality, but may not be widely and reliably available for a few months.

Trying to mine with an RP2040 is not useful, unless you want to be able to show your children in 10 years how you're just about to complete mining your first rupee's worth of BTC.

Make sure the TX of the ESP01 connects to the RX on the Pico and RX of the ESP01 connects to the TX on the Pico, if this dont work try another ESP01, you can also check the ESP01 is working as per the video above.

@@lambert0259 I tried this but I get lots of small squares filling up the shell screen. No characters. Any thoughts? Everything is plugged as it should (inc tx (esp) -> rx (pico) & rx (esp) -> tx (pico)

@@frankjimenez9407 the baud rate from the ESP01 is usually 115200 baud if the baud rate on the pico is set to anything else you will get garbage on the screen, hope this helps

@@lambert0259 yeah, I set the same baud rate. I tested it before using the esp01 usb adapter (like the video) and works as it should in the Arduino Serial Monitor. But when connected to Pico, I do not see anything but gibberish.

@@frankjimenez9407 if the ESP01 is working correctly( try it in the Arduino IDE monitor to confirm) the only other thing is try the other UART on the pico UART1 pins gp4(tx) and gp5(rx). these devices need quit a bit of power as indicated in the video. not enough power causes brownout, (reseting).
