@christophe-cluzel Yes, I got the same problem, I have been 3days to find out the solution, but no result.
I configure the RFM69 with ESP8266 as a gateway and Promini as a node.
The pin connections same with yours.
I realy need help to solve the problem
@christophe-cluzel Good luck. Using NRF24 & mysensors library, make IoT project is easy to be implemented. Thanks for mysensors team that have been developed this great library.
In the previous project, we have tested the range of NRF24. In the open-space, the 100m range can be easily achieved. If it is not enough, there are many modules of NRF24+PA+LNA that can have range for more than 1km.
My concern is the use of frequency at crowded 2.4GHz.
In my previous work, I installed my NRF24-based lamp controllers in an exhibition. In that place, the commitee provided a free wifi services. Before opening of the exhibition, we have tested the lamps controllers and working properly. However, during exhibition, the controller was not working. I suspected that this was due to no available channel at 2.4GHz band at that exhibition place. So, if there an option, I want to avoid the use of 2.4GHz band.
So, I still hope to use RFM69. May be someone have used this RFM69 module, and can share the pin connections and #define configuration in the arduino sketch.
Thanks
