Is there any requirements about hardware ? Wouldn't be surprised if this requires a raspberry or some specific wifi chip, so the raw frames can be sent ?

Re: ESP-Now support for ESP32 (and ESP8266)
Edit: I can find the MAC address of the hotspot but it looks like it doesn't know what to do with the ESP-Now data. As far as I know, the ESP-Now frames are vendor specific frames, and I don't think your wifi hotspot would even understand them. Further more, ESP-Now doesn't require the ESPs to be c...

Re: ESP-Now support for ESP32 (and ESP8266)
Hi, I've got a very first version of my Mesh library. Here are the current features : - Messages are always sent crypted, as broadcast (so we don't have to bind "known" peers) - When a message is received, we check its TTL : if it is more than zero, we resend it so a further node can have a chance o...

Re: ESP-Now support for ESP32 (and ESP8266)
without adding unacceptable power overhead for battery operated sensors which want to turn on the RF for the shortest possible time. That looks like a bit difficult : If the mesh network is only made of battery powered, no nodes will be capable of relaying the messages? If there is "always on" devi...

Re: ESP-Now support for ESP32 (and ESP8266)
I was in fact not adding bcast address on send function, it was my missing part ! That would definitiely be a cool contribution. I've also been looking at the Espressif ESP-MESH capability and thinking about wrapping that in a micropython module as well. Yes, I hope too ;) Have a look at this librar...

Re: ESP-Now support for ESP32 (and ESP8266)
Announces itself with a specific "discovery" message on broadcast (unencrypted) asking for a service name (eg. "broker") and waits for responses for a few seconds Any of my "broker" nodes that receive the message add the new device as an unencrypted peer and responds with an "Announce" response. Hi...
