@lunarok about power emission .. I test it in my house .. WiFi is different .. but in 2.4Ghz is problem with signal mirroring .. receiver detect more signal , all are same but little delayed .. then receiver not receive signal correct .. in free area there are not mirroring signal then with low output power can get long distance .. and low power consumption..
but in Built up area is better to use 868Mhz or 433Mhz .. there is also mirroring but less then 2.4Ghz .
I can test only nRF24L01+ with nRF905 or CC1101 .. but in fact .. in CC1101 or nRF905 is possible to set lower transmission speed then get longer distance ..
best regards..
or not ???
Yes, I get it from presentation messages, but like you say a little redundant
So, if I can send it once in setup, like this it's better for the controller, not too much work for nothing, just take care of the message send by setup and it's done.
