Logging Debug Data from IoT Embedded Devices over the GSM Network
Lubomir Valeriev Bogdanov · 2021
The paper discusses a specialized low-power embedded system that records any debug output over the UART interface of IoT devices. The acquired data is buffered locally and sent to a central server over the GSM network, at a predefined period of time. This logging device is battery powered and solar charging is applied to it. Certain parameters of the logger can be configured remotely.
