Raspberry Pi 3 and Sixfab shield gsm/gprs

I’ve a Raspberry Pi 3 with Sixfab shield gsm/gprs on ttyUSB0. I’ve set APN like hologram. I’ve installed Python SDK . When I execute sudo hologram send “Hello World” I’ve got this: ERROR: modem not detected.

The hologram command line tools will only work with the Nova, they wont work with 3rd party modems / shields such as the sixfab shield you mentioned.

Your options are either to heavily modify the hologram sdk to work with your setup (the hologram SDK is open source so you can fork / modify easily). Or just build your own using AT commands for the modem on the sixfab board.

If you want to get started quickly, best bet is to buy a Nova.
