Also OK on android 11. A bit smaller program to type less.... 

> I meant no typing was needed at all if the code was already on the hub, but thanks anyway! 😄 I was not on sharpest yesterday. Of course: one...

Seen the same on a block program where the first block has "x":0 and "Y":0 no other block has a negative position. example program ```python # pybricks blocks

Laurens, I ran your test programs with varying data lengths [above](https://github.com/pybricks/support/issues/1454#issuecomment-1952557784) with a TechnicHub as sender and a SpikeHub as observer. Both run Firmware v3.4.0b2. Removed the instantiation of the...

As promised.... (more or less) My PC rebooted involuntary, so no final measurement, the hubs are still sending and observing. At least six hours in this run without a problem.

Maybe a strange hit here..... The transmitting techhub with the small test program above, running disconnected from the PC, started to complain about low-battery. So long pressed the button, to...

I wanted to change the program in the technichub and noticed it got stuck in half an hour. At that time the large program also ran. Now: At the moment...
