If you change the baud (velocidade) to 9600 you should then see data in the serial window.
Then in EmonESP you need to change this line to 9600:
EmonESP/src.ino at master · openenergymonitor/EmonESP · GitHub
and re-compile and upload the EmonESP firmware to the EmonESP module
Or use the pre-compiled sketch that you (@TrystanLea ) provided that I gave the link to.
Thanks, but a silly question… how to upload this .bin file into emonESP using IDE?
@TrystanLea will tell you. I do not have an ESP8266.
I dont remember doing that, can you remind me of the forum post?
Umm…
I’m not surprised you don’t remember it, it was Glyn.

Ah, I have a feeling you have to do something to put those devices into boot mode.
[edit] yep GitHub - openenergymonitor/EmonESP: ESP8266 WIFI serial to emoncms link
[edit2] - can you not just do it OTA?
Hi, thanks for your support! Yes, you were right, I needed to press and hold GPIO0 button and press reset: It enters on bootload mode and finally the upload worked. The problem now is that the emonESP_xxxx wifi network is up but it’s not possible to connect to it. I tried different devices and re flashed the the emonESP but no success… Any idea, please?
Thanks,
borpin

Any error messages?
MarcioPaiva:
Any idea, please?
Sorry not from me - @TrystanLea @glyn.hudson can you help?
borpin:
Any error messages?
No. The device keeps trying to to connect forever… but no error messages…
borpin:
Sorry not from me
No problem at all… Sorry for all the hassle…
Everything seems to be ok…
@TrystanLea any idea, please? The bin file is not working…
Hi,
I have an emonESP with a firmware set to 9600 baud rate because I have the 3-phase sketch on my EmonTx. When I try to connect to the emonESP for the first time to start the config, the device keeps trying to connect to the emonESP_xxxx network with no success:
I’ve tried other devices, I re-flashed a lot of times with different tools. The server is starting as you can see below:
But when I flash the emonESP with a firmware set to 115200 baud rate this problem does not happen.
I don’t know what else I could do.
Thanks,
@Robert.Wall I have already compiled a new firmware with 9600 bps… same problem… and when I keep the 115200 bps it works…
@glyn.hudson
I pointed @MarcioPaiva towards your pre-compiled 9600 baud file for the ESP8266 - I think it’s that which won’t connect.
@MarcioPaiva
Can you try downloading the source file for your ESP and change the baud rate to 9600, compile and upload that?
It has worked in the past, for two users at least, I think.
We shall have to wait and see what Glyn says. I’m sorry you are having all this trouble.
