BlueShadow 0:37336794ce7e 1 /* This is an example program which reads in the 3-axis acceleration, pressure, and temperature data from
BlueShadow 1:ce1ed2844521 2 * a sensor board. It then uses an MTSAS SocketModem Shield board to send the read data over
BlueShadow 0:37336794ce7e 3 * a cellular connection to Aeris AerCloud using an MQTT client protocol.
