Hardware communication module with Wi-Fi and Bluetooth, connected to GPS trackers via RS-232 or RS-485 to extend device functionality.
The SIGMA module is supplied with a universal base firmware
AT-MODEM. This firmware allows control of the module using AT commands and enables the implementation of various functions:
- scanning Wi-Fi networks and Bluetooth devices;
- connecting to various Wi-Fi access points for data exchange;
- operating as an access point for other Wi-Fi devices;
- reading the input line status;
- controlling the output line.
When operating with
AT-MODEMfirmware, the SIGMA module is not a standalone device.
Its operating mode is defined by the navigation terminal or any other controlling device by sending the required AT commands.
