Daniel, I think you need to go to https://github.com/glenn20/micropython/tree/espnow-g20-8266 , click on the green code button and either clone or download the .zip file. I think you have to then build this. At https://www.eevblog.com/forum/beginners/micro-controller-mesh-network-micro-python-circui...

More searching and I think this sorts my requirements:

This project look interesting as I want to be able to reliably load-shed if my main power inverter fails, or else the standby inverter would be damaged. One of the many tutorials I read seemed to suggest that when the ESPs are configured as peer to peer that you couldn't then switch to WiFi operatio...

Changing to a 13v5 to 3V3 1A SMPS has sorted the re-boot issues.

Putting another 470uF on the output of the LM317N only slightly reduced the 80ms dips. There must be a high peak current draw somewhere.

Now I can see how long the link stays up.

Finally got the oscilloscope on the job. On the "faulty" unit the supply voltage dips from 3.0V to close to 2.5V every 80ms. I guess one of these dips gets close to the point where the ESP8266 re-boots. I am using a LM317N off a 5V supply with 470uF on the output. If the ESP8266 draws more than 100m...

Before I launch into a resilient WiFi implementation I would like to understand what is happening in my current setup. I am running a simple socket server on a ESP8266. It appears that when the link drops-out is that the ESP8266 re-boots automagically. Nothing in the code does a machine.reset(). So,...

Problem sorted.

Make certain that you are modifying the file that you are actually running on the device ... and not another one with a "similar" file name.

Apologies for wasting your time.

Well, putting the resistors to 3V3 correctly made no change.

If I read the file back on WebREPL I see the current changes but it appears that after doing a hard reset that that is not the file running on the device.

I try re-flashing the firmware or another ESP-01S

I made a wrong assumption ... I just made a spelling change in the server script and it did NOT update on the device. I now see those extra 3K3 resistors I put in are not going to 3V3 but to my reset button ;( However, I had this "problem" before I put them in. Thank you for your effort thus far, I'...

Oops, yes the code is changed on the device at each change. I check by getting the file back.

Is there some issue with handling the socket that I am not aware of?
