Moteino rf95 Examples

[jcozzy]

Hey everyone!

I just received 2 Moteino RFM95's and tried the Radiohead client and server examples using latest Arduino IDE with the Arduino Uno as the board selected.  See following video:

The only change to the examples I made was the #define FREQUENCY 915 line due to concern of default values.  I do not even get serial output for these codes.

Any suggestions?

Hi jcozzy!

Hmmm, did you try the library from my RadioHead link on the LoRa guide page, or did you get the latest RadioHead?

Thanks for the reply, I think it was the latest Radiohead, I tried the Radiohead version 1.83 from the link you provided and got this error on both client and server, respectively (I will try some editing):

The Reliable_Datagram versions compile, but they also give no serial.  I see this warnng in the code: "Ensure serial flash is not interfering with radio communication on SPI bus"

Might that be an issue?

Make sure there is only 1 version of RadioHead installed on your system. If you have two you will get those errors.
You may have one installed manually in your arduino/libraries folder (or two conflicting libs) or you may have a manual version installed and one from the Library manager.
