[SOLVED] Nodes not receviving ACK from Pi3 gateway

[olision]

Hi everyone,

I have been running a sensor node with a nrf52832 talking to an Arduino Uno and a NRF24L01+ for the mqtt Gateway without trouble. Recently I wanted to run the Gateway on my Raspberry Pi that is already running Openhab with the Embedded MQTT Broker. I followed the installations and setup guidelines, installing the latest development rep. The test does make a connection to the NRF24L01+ chip as the logs here:

But on the other side, on the debug from my node I have:

I used the configuration line :

./configure --my-transport=rf24 --my-rf24-pa-level=RF24_PA_MAX --my-rf24-ce-pin=26 --my-rf24-cs-pin=24 --my-gateway=mqtt --my-controller-ip-address=127.0.0.1  --my-port=1883  --my-mqtt-publish-topic-prefix=mygateway1-out --my-mqtt-subscribe-topic-prefix=mygateway1-in --my-mqtt-client-id=Gateway

Which is most alike than what I had on my Arduino Uno Gateway.

Did I miss anything to make it works?

Thanks for your help on that matter!

@olision actually, the nodes do receive ack, as indicated by st=OK.

Does the gateway log cover the time when the node sent its messages? In that case, maybe there is another gateway (or a repeater node) that send the acks?

What capacitor(s) are you using for the power on the gateway radio? How is the gateway radio powered?

Thanks for your fast reply,

In my case, there is only one Gateway running on the Pi3 and only one NRF52832 node. I have a 10uf capacitor soldered on the NRF24L01+ and it is powered using the 3.3V form the Raspberry Pi. To make sure it wasn't a faulty radio, it is the same I used on my working Arduino gateway.
I saw in the configure help that there is a --my-rf24-channel=<0-125> option set to 76 by default. Could it be the cause of this communication error?

I'm all ears if you have any recommendation to my setup to make it works!

Finally got some time to work on it. I started back from scratch, installing the openhabian image and configuring it all over. I problably made a mistake somewhere because now it does works well!
