This is great, #104 asks about using multiple radios, this could assist with that. I'll try to give this a test this week.

Why not a member variable?
edit: I ask about the reason: programming, compiling, resources or design pattern?

[morganrallen]

Agreed, in order to make this work with multiple SX1276 devices at the same time, this would need to be part of the class.

[Rotzbua]

@morganrallen For multiple devices are not multiple spi bus required. So 1 spi will work with 4-7 devices.

[morganrallen]

Oh right, I even commented that on #104

The important part is the interrupt of each device @morganrallen are u working on this now?

[morganrallen]

I'm not actively working on this yet, I hope to get time tomorrow or Saturday

@wero1414 @morganrallen I think a LoRa.setSPI(...) API would be a better fit rather than adding parameters to begin this was discussed with @facchinm. It's not specific to multiple radios. @facchinm's main goal was to get the MKR WAN "dumb" radio example working with this lib: https://github.com/arduino-libraries/MKRWAN/blob/master/examples/DumbModemLoraSender/DumbModemLoraSender.ino

Let me comment on #104 regarding multiple radios.

Closing in favour of #105.
