» 3G 21: Uploading files to a FTPS server from Waspmote’s SD

This example shows how to upload a file to a FTPS server from Waspmote's SD card

Required Materials

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

Notes

- 3G module must be powered with a battery
- When 3G is in use, interrupts can't be used
- 8.3 codification for name of the files
- Be sure that the name and the path are correct
- The 3G+ GPS module doesn’t support FTPS server with certificate authentication. An explicit FTPS server without certificate authentication must be used with these functions
- This example can be executed in Waspmote v12 and Waspmote v15
