Cannot switch multiple Crownstones at once

[RicArch97]

This was a test of switching multiple Crownstones at once. The following Crownstones were tested:

• Plug (Dimming enabled)
• Plug (Dimming disabled)
• Plug (Dimming disabled)
• Plug (Dimming disabled)

Crownstones are switched using their respective switch functions:

• dim_crownstone(id, val) for a Crownstone that can dim
• switch_crownstone(id, on_state) for Crownstone that cannot dim

Following debug logs were found suggesting that the correct data was indeed sent to each Crownstone:

However only 2 of those Crownstones was actually switched each time. The Crownstone that can dim, and 1 of the relay Crownstones.

The multi switch does work correctly with the cloud implementation however.

Hi ricardo, I suspect this is because the python library doesn't wait for a reply yet (@AlexDM0 correct me if i'm wrong), but just sends all commands at once.
All commands before the reply are simply ignored. So for now, you'll have to add a little delay in between commands. If there's a "multiswitch" implementation, you could use that instead of all single switch commands.
