ESPNow Agora

[ChrisMicro]

For the Arduino framework there is an extremely simple library for ESPNow.
Agora Example

The main advantage is that you do not need to fiddle out the MAC-aderesses and you can just use names instead. The MAC-addresses are invisible to the user because he does not need to know them.
I think a library like Agora could be extremely useful in Micropython. What do you think?

The concept of ESPNOW name resolution might be interesting.
I think the implementation has several poor choices in the name and "protocol" conventions that I do not support to propagate, but that is just my personal standard.

Building a registry service that listens on a broadcast address and provides name/Mac mapping is simple to implement and can coexist using asyncio.
Adding closed groups and security is more complex.

Yes, the terms of "guru" and "follower" seem to be an attempt to get rid of the terms "master" and "slave" even if the examples contain the old naming.

I understand the terminology in the following way:
tribe => network name
guru => master
follower => slave

I saw a demonstration of ESP-Now with the AGORA library and was impressed. No time delay establishing the connection like with WIFI-sockets. It was in the ms range. This enables the usage as wake up sensor devices with low energy consumption.

It would be a pity when the original name of the author with this very good idea would be lost when translating it to Python. But I see it is difficult to establish a new naming.

#Adding closed groups and security is more complex.
You are right. For serious application encryption of the AGORA link would be a must. I do not now, if some algorithms of other projects could be easily adapted.
