<![CDATA[Need help with Raspberry Pi Gateway]]>I have 4 Nano/NRF24 sensor nodes with NODE-ID's defined in the sketches.
They work just fine with a W5100 MQTT Gateway, all nodes are recognized and messages passed to the MQTT broker. However when I instead use a Raspberry Pi, configured as a MQTT gateway, only one of the nodes seems to be recognized. What do I need to do to have all nodes recognized (two sensor nodes have the same 105 NODE_ID)?

I must say, the power issue is mentioned often enough on MySensors.org that I should have tried that solution a long time ago.
Thanks again.

The RPI is powered from the USB port on my ASUS router (I had powered it from a 2.5 amp USB source in the past with no change in result). However, I had been using the NRF24L01 with the antenna; I changed the radio to a NRF24L01+ and -- success! So it must be a power issue after all. I have used the antenna version on the sensors in the past with no problems. I haven't used capacitors yet, I'll try those soon. But for the moment, I'm back in operation.
Thank you!

How do you power the nrf24 on the rpi? What cap did you use on the radio?
