PI 3 and Arduino uno: no communcation

[Stef Coene]

Hi,

I attached a nrf24l01 with 5 -> 3,3 V convertor to a PI3 and a Arduino uno.
Running mysgw on the PI shows no error.
The Arduino uno is also starting fine, but it cant' find the PI.

I measured the 3.3V voltage and that's find. I don't see any drops.
I soldered a capacitor on the VCC of both nrf24l01.
Placing the PI and the Arduino closer togeher is also not helping.

What else can I try?

First you need to define a node ID on Arduino. Second, did you put a capacitor near the radio module?

[Stef Coene]

Capacitor is soldered on both modules.

And I thought the Arduino is broadcasting to the GW to request a node ID?

Stef

[gohan]

but it needs a controller to assign the ID, gateway is pretty much dumb

[Stef Coene]

I have Openhab running as controller.

But still, shouldn't I see any communication between the PI and Arduino?

Stef

[gohan]

you should, anyway just add the node id and try with mysensors library from development branch.

You may also try to make a USB gateway with another arduino and see if you see any change. If you have more radio modules try them too. Sometimes it is just a faulty radio module and you loose all that time for nothing

[Stef Coene]

I finally had some time to do some further testing.
Switching to the development branch of MySensors solved my problem.
I have the feeling that the link is not really stable, but at least I can see data coming in.
