Hey

So I've replaced the esp01 for esp01s and it works flawlessly. Thanks for your help. Just need to find a use for the old units now.

Will get an esp01s WiFi module from the UK. If it works I'll bulk buy for the project. Can't thank you enough for the help. I'll test the voltage tomorrow

I'll test it tomorrow. I might just grab some esp01s units. However most sellers.are not in the UK.

So I need to get some.esp01s WiFi boards to use my relays?

See photo.

I can does reading tomorrow. It has esp01s printed on the rear of the relay if that helps

Possible. However I wanted to use this relay due to the size. Which sucks!

Balls! Powered from arud and it's booted.

Just a question. Why does it work from the programmer without the link out? Why is it then needed?

I'll try powering from my arudino.

Not sure if it is 1mb. And no I haven't booted away from the relay. As I don't have a 3.3 psu

I sure do.

Really want to get this to work. But im on the verge of giving up. A lot of information online is different from one page to another.

Ok all soldered. Still not connecting to my network ;(

Yes I do. I have a standard ftdi programmer. I will send over a photo to.orrow if you don't mind. By soldering those pins does that mean it's in bootloader mode 247? I thought these where the pins I shorted to flash the firmware.

When I disconnect it from the programmer I don't have anything connected to the unit no serial info. As I said it works fine when connected to the programmer. I am able to connect via the IP address. When disconnected from the programmer it doesn't appear on my network.

Im really not getting this. My unit has been flashed with firmware. Just doesn't connect.to WiFi after I disconnect it from the usb programmer and just apply power.

Placed a 10k resistor between vcc and Ch Eng and getting the same.problem. any ideas

OK just to check Solder VCC to CH-ENG then power up

Sorry being thick today.

Ok cool. so just solder those two terminals. Then power up? or do i need to connect GPIO0 to something also on boot uo?

Thank you. How can I do this while connected to the Relay board?

looking into the further and look like i need to boot into "boot from flash mode" how do i go about this? Am i guessing the USB programmer goes into boot from flash as default?

I will do when i get home. All i did was plug the esp-01 into the yellow connector of the relay.

Hi, I am having issues with a ESP-01 connected to a relay. When the ESP-01 is connected to my USB programmer the device connects to my network. When i connect the ESP-01 to the relay and power the relay the ESP-01 turns on but doesn't connect to my network. The ESP-01 flashed fine and ESP easy was s...
