Thank you both for your answers, that clears up most of the confusion I had around that subject! For my first prototype I might go with the BM832 and a on board regulator like Nca78 mentionned.

Hi everyone,

I have developped my node on the NRF52832 DK using the MySensors library and now I'm starting to work on making a custom pcb using that chip rather than an Arduino and NRF24l01+. I stopped my choices on 3 chips for now which are: Fanstel BM832, Fanstel BC840M or the Raytac MDBT50Q – 1M (which uses a chip antenna rather than the pcb on the Fanstel ones).
For me, I think the only advantages choosing a nrf52840 over the nrf52832 is the range according to the spec sheets and the possibility to connect a LiPo battery directly without using a voltage regulator. On that later, is it more energy efficient to use the LiPo battery directly than using an external LDO?

Has anyone tried those chips on a MySensor sketch or built their own sensors using those chips? Any other recommendations or one I should go with for my custom PCB?

Thanks for your help making that component choice!

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!

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!

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:

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!
