About

I am mainly here for the Bluetooth.

Most repeated is about deprecated BlueZ tools:

hciattach, hciconfig, hcitool, hcidump, rfcomm, sdptool, ciptool, and gatttool were deprecated by the BlueZ project in 2017. If you are following a tutorial that uses them, there is a chance that it might be out of date


Python Linux BLE Client example: https://stackoverflow.com/a/63751113/7721752


To get Bluetooth debug information on Linux:

  • Are you able to connect to the device using bluetoothctl?
  • Does service bluetooth status show errors?

When running your script have separate terminals open with the following running to get more debug information:

  • bluetootctl
  • journalctl -f -u bluetooth
  • sudo busctl monitor org.bluez
  • sudo btmon
