RFM69HCW fails to initialise

Hi, I recently bought 2 Adafruit RFM69HCW LoRa modules for a project.

I have followed the Adafruit tutorial on setting these modules up. I connected them to a genuine Arduino Uno and used the RadioHead library as described in the tutorial. I have also connected an appropriate antenna for the frequency. Both modules give the same error on the init() call, returning “LoRa radio init failed” message. I have double checked the soldering and the connections to the Uno without success.

I have looked on Googled for an answer but only find people with similar problems and no solution.

Can anyone suggest what the problem may be?

Thanks Ernie

The RFM69 modules aren’t LoRa modules. The RFM9x modules are LoRa.

Hi, Thanks for the feedback. That might explain my problem. The numbers are so similar.

Thanks again

Ernie

Not only the numbers, but the frequency they work with is also similar. I also always have to check twice to get the correct ones.

But you might want to just use these modules. This really depends if you need LoRa or just an efficient form of radio transmission.
