@kajmaj I can only refer back again to what was discussed and was worked out in the example I posted initially. @Bard do you mind assisting in this post?
For sending an array of static values worked by using the below syntax
Now I am curious to know what the actual values of your register bits are at present?
You said:
What then happens if you send [0,0,0,0,1,0,0]
It seems that would/may fulfiill what you want to set ie: bit 4=1 and bit 6=0
