Next, wire up a BME280 to your board. If you'd like to avoid soldering directly to the FONA shield, you can pick up some shield stacking headers and some jumper cables.
Attach Antennas and Battery
A battery and GSM antenna is required to use the Cellular module. If you want to use GPS as well, a passive GPS antenna is also required
Check polarity for the battery!
Snap the uFL connector on, it will click when placed properly
All of the above are REQUIRED! Flaky behavior is often a low battery, no SIM, no GSM antenna, etc!
You must insert a SIM card to do anything but the most basic tests. The shield and GPS does work without a SIM but of course you cannot send or receive texts, calls, etc!
- If you have not yet inserted a SIM card into your FONA, follow the instructions on this page and come back to this guide when you're done.
