Well, I've had enough of Christmas now and itching to get on with this - I will indeed update the code on the 3 units I have running and let you know if I spot anything - looking forward to being able to make use of this with my router so as to extend the range beyond that of interconnected ESP-01 boards... my goal is in February to take a bunch of boards to Spain with me and leave a functioning network, remotely and reasonably securely accessed by my phone - I'm counting on you :-)

I think that's probably more important than MAC number??

Thanks Scargill.
1. Signal strength issue has been corrected.
2. Some debug display changed, now it will indicate " AP GOOD ...-> "MESH-66032", -61" which means current AP with which ESP is connected with RSSI value (Note, RSSI will be changing after 2 min interval, although at 15 sec, it is just checking either current AP is available or not".[ There is another smart way to get interrupt when AP lost, instead of periodic checking. I am thinking on it]

The connection problem is happening when All devices are started almost at same time and all are trying "to allow to join with him" and "to join with others".

Well, MAC is fine, but when Espressif released the API to change the MAC, it became unstable to use MAC as unique identity. Hence, I am preferring to use the other way to get unique signature of each ESP.

Waiting some more observation/bug before uploading the binary.

[Update]
A random delay from 1 to 60 sec has been introduced at starting before AP association. Expected, links will be stable.
Place nodes with some distance (>10 m ?) for stable linking.

Sadly I can't help with debugging: one of my ESPs is non flashable (v080) and the other is also in 'production'. I'm tempted to cut some traces on the ESP-01 to make it upgradable.

Hopefully I'll be buying more shortly and can help afterwards. Anyone has a reliable souce for cheap and good quality ESP-12?

Thanks!
