A modification of the MKRNB library which provides an Arduino Client interface for a SARA R4 connected through any Serial interface.
This library mostly follows the MKRNB reference: http://www.arduino.cc/en/Reference/MKRNB
However, all classes must now be initialized with a Modem
.
SoftwareSerial r4(8,9);
Modem modem(r4, 115200, 5, 6);
NBClient client(modem);
