Hi @jpwhitney.
Had you had any luck using it with 900HP?

No, it seems like it should work, but I haven't had a chance to look into it in depth.

This library is still more low level than would be ideal for my purposes. It'd be great to have a function where I could send a string from one Arduino to another by passing in the string and the 2nd Arduino's address and then have a confirmation that the signal was received successfully and accurately. But unfortunately such a function doesn't seem to exist in this library and I do not currently have the knowledge to create one.

Are you trying to do a similar thing?

I'm in the same boat I've had no luck getting this to work with the 900HP
