» 3G 09: Getting RSSI and network info

This example shows how to get RSSI level and network info

Required Materials

1 x Waspmote
1 x battery
1 x 3G + GPS module
1 x GPRS/3G antenna
1 x SIM card

Notes

- 3G module must be powered with a battery
- When 3G is in use, interrupts can't be used
- This exampe can be executed in Waspmote v12 and Waspmote v15
