No. "Blockly4Thymio" is an application provided by a third party community developer, Okimi. As it has not been maintained for a few years, it is compatible only with the older versions of Aseba (up to version 1.5.5) and of the Thymio firmware (up to version 9). Please note that Thymio robots produced after end 2019 -from series T on- will not be compatible with firmwares older than version 13.
Therefore, we strongly recommend that “Blockly4Thymio” users switch to Blockly and/or Scratch v3, both of which are included in Thymio Suite 2.0.
