Re: Controlling LoRa radio with IOIO

[Jerry Howard]

Thanks for the advice.  We may very well go with the route of communicating 
with arduino over USB.  
Regards,  Jerry

Re: Controlling LoRa radio with IOIO

[Ytai Ben-Tsvi]

I don't know specifically about this radio, but indeed SPI is possible.
Usually, unless the device has some weird timing requirements, there should
be no problem. You should be able to translate the Arduino-based library to
Java.
Alternatively, you can leave the Arduino in the loop and use the Android as
display only. In this case, what I would do is have the Arduino present the
data that needs to be displayed over UART or I2C and consume it via a IOIO.
Another option is not to use the IOIO and use one of the Arduino boards
that can talk to Android over USB or add a Bluetooth shield to the Arduino.
