@subutux I've updated the text. Do you think it is ok?

yup! thanks!

@subutux it is mentioned as stated above that you need it, it is just skipping all the info that are in datasheets and are not stricly necessary to make the gateway

Well, I for one would like to know why we need to step-down from 5v to 3.3v. Just a simple statement that the LNA version requires more power that only the 5v can deliver on the pi.
@mfalkvidd Yeah I would mention it there. It mentions to use a regulator but not why.. I've read that line & was like, why? That's when I've started a search in the forums here.

@gohan said in Building a Raspberry Pi Gateway:

yes, the 3.3v can't supply enough current. I am using some small adapters that have the AMS1117 and some capacitors that allow for a quick swap of radio modules when you need test them

Ok. Maybe this should be mentioned in the documentation page.

@Roberto-Mo-Ca If you are using the nrf24 PA/LNA version you need to use a 5V->3.3V regulator otherwise you can connect to the 3.3v pin.

But why do we need to convert down from 5v to 3.3v? The pi does supply 3.3 on some pins.. Is this because the PA/LNA uses more mA?

@martinhjelmare As soon as i have the time (and clean up my code because it was a hack) i'll create a pull request. i've mine also at 0.02 and my (pi zero) CPU is now at around 8-10%.

Hi,

I've also tested your pymysensors version with tcp gateway. I've had an excessive cpu usage on my pi Zero (actually, a constant 100%). After some debugging I've found that I've had to add a sleep of 0.2 to the while loop of the top socket readout. My cpu usage returned normal.

What I've also encountered is that when the tcp gateway looses connection, pymysensors still thinks it's connected. I've buildin an active check by requesting the gateway version every 10 seconds.

Would you like me to make a pull request ?
