Hi, I'm trying to make work the RFM69HW (433MHZ) modules in two Arduinos UNO.
I'm connecting to SPI ping in the uno board as is showing in this picture:
I'm using this library GitHub - LowPowerLab/RFM69: RFM69 library for RFM69W, RFM69HW, RFM69CW, RFM69HCW (semtech SX1231, SX1231H) with the examples; Gateway and Node
In each code I've uncommented the option
#define IS_RFM69HW
And I set the frequency to "433MHZ"
I uploaded each sketch to each Arduino UNO, but the message is not receiving for the Gateway. I can see in the serial monitor the sending message, and an error (not sended).
I tried the connections but all seems to be fine. I'm wrong with some thing?
Can I communicate two Arduinos as I'm doing?
I'll appreciate any information.
