@NeverDie Yes, you are correct - it is based on ATMega1284P. So not relevant
My point is that I'd rather stick to the datasheet rather than overclock, but that's just me. And yes I realise that Moteino is overclocking, but the size, voltage and flash are really appealing to me.
@DirkB19 Think you will get another advantage by changing as well - must be a lot easier to monitor the MQTT messages when topic clearly shows the difference.
@Yveaux I have 34 of 80k RAM used for this sketch, so 128 bytes looks like "a bit more".
You can not use progmem with ESP and mysensors now because PSTR redefined as PSTR(x) (x) so all strings are really in RAM
@scalz
in the second test i used that getting started code to test the radio modules with a library other than mysensors. and they worked. (That code is not mine, i suppose it use the maniacbug library).
So i did investigate to find the differences between mysensors and that library. Only after replacing, in mysensors, the enablefeatures with that code, i got the communication gw-node.
