Which is better: RFM69 or NRF24L01+?
-
Sorry for so basic question --- But I think you needed to adapt the gateway, in order to run both radios together (mix of RFM69 and nRF24L01+ nodes) ?
-
@rvendrame yes I running 2 serial gateways on my Domoticz controller.
-
I agree with you too. RFM is very good quality and @tbowmo GW will be sooo great! atsam is little beast and our GW will be much much powerful! Like some people I prefer not using wifi for GW (security question for me), usb is much more secure I think. And for radio, RFM is a killer!
-
@rvendrame I give all my nodes static ID's and this is working for me in Domoticz
-
If you were starting from scratch, would you still put both radio types in your system, or would you put all of one type only?
-
@rvendrame I will only go for the RFM69. When I start playing with the Mysensor project Hek only had only support for the NRF24l01+. Once they port the library over to support the RFM69 I stop using the NRF24L01+. Luckly I don't have big installation on the NRF24 radio.

@Francois darn, by now i can wire the nrf from memory. Now to learn new wiring....
The power consumption in idle is still something to consider -

According to JeeLabs, " The RFM69 draws 0.1 µA in sleep mode." Say, isn't that lower than for the NRF24L01+?
Or, by "idle," were you referring to something else?

@NeverDie I mean in reality... people here measured 30uA compared to 3uA in similar nrf setup. could be the result of many things, might be just a kink that has to be ironed in the software.

I haven't measured it myself, so I'm very open to everybody's data. Hopefully more people will post results of their own measurements and a pattern will emerge suggesting what's truth.

Hi,
Anyone got the Ethernet gateway going with RFM69? I am struggling and I am not sure, but I think there are a few issues in the V1.5 for RFM69.
@NeverDie, a 78mm piece of wire works well for antenna.
*Edit - Sorry, this is assuming 915MHz. See https://www.easycalculation.com/physics/electromagnetism/antenna-wavelength.php and choose quater wavelength -

Does it make any difference what the wire diameter is? I'm assuming the thicker the better?

@NeverDie Probably, but I don't think you should stress too much. The power is not "that" high.
See http://ham.stackexchange.com/questions/140/good-wire-for-wire-antenna for what seems like valid response.

Right, I'm just not t sure how to account for the "skin effect".
