I am trying to get an RFM69HCW working with Pro Micros. I am using 868 MHZ RFM69 modules. The RadioHead Library examples both work well, if I initialise the rf69 with Pro Micro pin 10 for the chip select and Pro Micro pin 3 for DIO0 on the RFM69.

Code: Select all

RH_RF69 rf69(10, 3);

I also try to test exactly the same setup with the LowPowerLab RFM69 library (the node and gateway examples), but I get no transmissions between my units. It took me a while to find this out, but after much reading I think it's ok if I initialise as follows:

Code: Select all

#define RF69_SPI_CS   10
#define RF69_IRQ_PIN  3

The radio is then initialised with:

Code: Select all

RFM69 radio(RF69_SPI_CS, RF69_IRQ_PIN, true);

This setup is not transmitting - the node always receives "nothing" back for its messages. Nothing shows up on the gateway serial monitor (I can call the different functions like i, t, or similar.

I would much appreciate any help in understanding what might be the difference between the two libraries and how to get the radio module working with the LowPowerLab library.
