WHID_TestSuite.ino is a testing suite, based on the existing one from FONA library, that allows to test if the SIM800L works properly.

SIM800 will boot and you can type ? To see the commands available. TODO: Finish to add k command and all other possible unit-tests to check WHID Elite's functionalities. E.g. spy, askTX, askRX, etc...
