Vanger 1:76498fdfbecf 1 /* This is an example program which reads in the 3-axis acceleration, pressure, and temperature data from
Vanger 1:76498fdfbecf 2 * a FRDM-FXS-MULTI sensor board. It then uses an MTSAS SocketModem Shield board to send the read data over
mchowla 4:81c6b9d73cb1 3 * a cellular connection to Aeris AerCloud using an MQTT client protocol.
