Robotics” value to set the script variable.įollowing screenshot shows the USB devices connected to my Raspberry Pi –įollowing code will help you reset USB devices connected to your Raspberry Pi. If you face issues with the copy paste of the code, you can download it from my GitHub Repo – #. Locate the manufacturer/device name for your device and use that to set the value for “USB_DEV_NAME” variable. You can use the “ lsusb” command on the shell prompt of your Raspberry Pi to list all the USB devices connected to your Raspberry Pi. This script uses a “ USB_DEV_NAME” variable to identify the right device while performing the USB port reset operation. At times the modem was becoming unresponsive especially during the testing, and to deal with this situation I wrote this python script and made it part of the auto port recovery method. I faced similar issues with one of the applications that I was developing with Raspberry Pi and U.S. Most of the times you will end up rebooting your Raspberry Pi to fix the problem. If you are working with the Serial devices connected to the Raspberry Pi, For example, a USB analog modem you may have noticed that sometimes these devices become unresponsive and don’t respond to the issued commands.

This database is meant to act as a temporary place for all incoming data which can then be requested by any backend service. The Node ID and the sensor type are set as primary keys in the database. The SQLite database is overwritten each time new data comes in from the same node. The actual sensor type, sensor value or number of sensor types is not relevant, as the script splits any incoming data, as long as it is formatted correctly. The script splits each data set by commas and makes a dictionary of the data split by colons. In the above example, i is node ID, t is temperature, h is relative humidity and l is light intensity. The letters indicate sensor type, and the numbers indicate sensor value. All incoming data is expected to be terminated by line break (\n or println in Arduino) and in the following format: The Moteino receives data from other Moteinos, each identified by their node IDs. This script is created to read data from a Moteino that’s connected to the Raspberry Pi via USB. The SQLite table is created if it doesn’t exist. This is a Python script that reads all incoming data on the serial port on Raspberry Pi and writes to an SQLite database.
