LTE modem

The LTE modem is build in the Patron S167, M267 and M567 units.

The unipi-lte package, which makes the use of an LTE modem available, also includes a virtual serial line for communication with the modem via AT commands. Modem settings could be managed for example, by the minicom program, directly from the unit's Linux console (by SSH access).

In the control SW (Node-RED, etc.) the serial line can be used, for example, to send and receive SMS messages or calls.

Since this is a virtual serial line, communication parameters (baudrate, parity, etc.) can be selected arbitrarily.
