Hi,

In [https://www.universal-robots.com/how-tos-and-faqs/how-to/ur-how-tos/real-time-data-exchange-rtde-guide-22229/](https://www.universal-robots.com/how-tos-and-faqs/how-to/ur-how-tos/real-time-data-exchange-rtde-guide-22229/)

the RTDE\_DATA\_PACKAGE frame do not contains recipe\_id in version 1 of the protocol. This is not explained.

Bye
