Re: BLE + Deep Sleep?
Thank you for the interesting link. Now I would like to know what exactly happens regarding retransmissions and akknowledge when sending to all know peers, like esp_now_send(NULL, data, len); /* send to all known peers */ Will there be retransmissions? In what sequence (when multiple peers are not r...

Re: BLE + Deep Sleep?
Yes, it may be a good option, but no, it is not acknowledged.ESP-NOW may be a good option as it is connection-less and acknowledged.
It is not difficult to program an acknowledgement if you want to have that.

Re: How to check Arduino version?
EDIT: I posted a message yesterday about ESP_ARDUINO_VERSION_MAJOR not being defined any more in 2.0.4
The massage was wrong, somehow I managed to screw things up...
There is no problem with these version related macros.
Sorry for spreading false news

Re: ESP-NOW: how to identify devices after boot?
Sorry I don't have example code neither, but I do have code of a project that uses a similar functionality to configure and play an 'orchestra' of esp32 'instruments', so you might find a couple of hints grepping through the code. But be warned: the code is long quite complicated, chaotic, experimen...

Re: 1.0.5-rc2 ESPNOW: Peer channel is not equal to the home channel, send fail!
Yes your post helped me a lot. Using WIFI_SECOND_CHAN_NONE did the trick. I can switch the channel without error messages now. I had tried a long time to switch to channel 4. This channel looks best on a WiFi analysing app. The connection was very slow and there was a lot of data corruption. So I fi...
