If your 4G LTE module doesn‟t come with SIM card slot, you can insert the SIM card into the SIM
card slot on board.
If your 4G LTE module already has SIM card slot, you can insert the SIM card into either SIM card
slot: the one on 4G LTE module or the one on PiGear Nano board.
Remarks: connecting two SIM cards to both SIM card slots will not work.
PiGear Nano uses GPIO-6 to control the power supply to the 4G LTE module, and uses GPIO-7 to
reset the module. If you install the software for PiGear Nano, the daemon.sh script will automatically
configure GPIO-6 and GPIO-7 to enable the 4G LTE module (if present). If you want to use it without
installing the software, you will need to set GPIO-6 to HIGH and GPIO-7 to LOW with these two
commands:
Remarks: you will then need to wait 5~10 seconds before running the
“lsusb” command to
see the 4G LTE module gets recongized.
When 4G LTE module is used in a remote site, and network is lost due to any reason, you may want
to reset the 4G LTE module or even make a full power cycle to get it work again. You can set GPIO-7
to HIGH to reset the 4G LT
E module, if it still doesn‟t work properly. You can set GPIO-6 to LOW to
cut the power for 4G LTE module, and then set GPIO-6 back to HIGH to power the 4G LTE module
again. This can also be done by a program running in the background, who checks the network with
a fixed inteval and will reset/power cycle the 4G module when the network is not good.
