yes @jeremypoulter, i is refering to the Wifi relay.
I followed the instructions, but the LED does not flash again, it is always on.
when I received the relay wifi, I made a copy of memory. (For security).
i used this command.
Oh dear, it sounds like there may be a problem with the 2nd wifi relay, @Martin_Harizanov should be able to help you debug further.
Can you check and see if both of your wifi relays are running the same firmware version?
Is your older wifi relay connected to the same network you are trying to connect the new unit to? Have you tried connecting to a different wifi network just to test?
Hello,
Is the LED constantly on withut any blinks?
Can you post what is available on the serial output?
And yes - pressing and holding the button for 3 seconds puts the device in AP mode.
Also - copying FW from one device to another isn’t a good idea, I suspect this is what lead to bricking yours.
I don’t get it, I personally flashed and tested that board for ~30 minutes. What do you mean by that, it stopped working after you modified the firmware, or was it dead on arrival?
The firmware won’t work if copied from one board to another, you shouldn’t do that.
You cannot re-flash the board once you have damaged the flash configuration area by uploading third party firmware. The firmware has tamper detection and it kicks in. I program that area specific to each board, so it knows the firmware it runs is genuine. That’s why you cannot copy one boards firmware onto another, the firmware will know and enter safe mode.
I suggest you send back the board, I will re-configure it and ship it back.
ok, now I understand everything, I lost a lot of time with this.
I do not understand why you gave me recover files if it was not valid, I’ve lost a lot of valuable time trying to fix it.
I will send you the board for you re-configure it.
@glyn.hudson please, you have to change the method of recovery of the wifi relay. this does not work.
Can I use the alternative firmware to repair the board?
The recovery firmware I sent was custom tailored to your board and an effort from my side to help you resolve the issue remotely. I have no idea why it didn’t work for you, but lets appreciate the hours I spent trying to help you remotely.
I think @pychu sending the relay to me directly is best option, you send a replacement, then I include the repaired board in a next batch delivery to you. How does that sound?
Am I reading this correctly in that even if I have backed up my original firmware using esptool, I will not be able to restore it again after loading any other firmware (even on the same board)?
@glyn.hudson if this is the case, it would be good to make this clear in the wiki. I had backed up my current firmware intending to do a bit of messing around customising it, but don’t want to risk losing the already highly functional original firmware it came with. Especially since the open source version is many commits behind my oem version.
