Pybrics for SPIKE (City, BOOST) and EV3.

[Eco-Beny]

Dear Experts

The students installed PYBRICS on SPIKE, BOOST and CITY. The hubs communicate with each other via Bluetooth. The robot works, the motors turn on as needed...
Now the students want to add an EV3 (with motors and sensors) to this robotto get a more complex solution.

Is this possible within Pybrics?
Or how can this be done?

In Pybricks, the newer hubs use Bluetooth Low Energy and the EV3 uses Bluetooth Classic, so direct Bluetooth communication isn't possible. (Technically, the SPIKE Bluetooth chip is dual-mode capable, but Pybricks doesn't make use of the Bluetooth classic there yet.)

So you will have to get creative. Here are some ideas:

• You could use a computer as a relay for converting messages between the different kinds of hubs.
• If you want to use experimental Pybricks firmware from the nightly builds, you could make a UART crossover cable to connect two sensor ports together.
• Or possibly you could use the BOOST Color/Distance sensor to send infrared commands that could be received by the EV3 IR sensor.

Kids would prefer block programing for EV3....
If I understand correctly (MINDSTORM Legends), the set of Lego Hubs for Pybricks block programming (Spike, Mindstorm, Essential, City, Boost, Technic) will be expanded with EV3.
Is this is already possible if I buy an additional monthly license (9€+VAT).

Is this additional monthly license "uprgarade" of existing Pybricks license (I have it since summer 2024)?

When EV3 is ready, it will be included for everyone. No need for additional licenses if you already have one.
